Gastroenteritis outbreaks associated with Norwalk-like viruses and their investigation by nested RT-PCR. (1/790)

BACKGROUND: Norwalk-like viruses are the most common cause of gastroenteritis outbreaks and sporadic cases of vomiting and diarrhoea. In healthy individuals infection is often mild and short-lived but in debilitated patients infection can be severe. It is essential that the virus laboratory can offer a sensitive and specific test, delivered in a timely manner. METHODS: We have developed a nested reverse transcriptase PCR based on published primers against the RNA polymerase gene and after comparison with electronmicroscopy used the assay to investigate 31 outbreaks of gastroenteritis. These were in diverse situations including nursing homes, small district hospitals, large general hospitals, a ferry ship, hotels, restaurants and staff canteens. RESULTS: A positive diagnosis was made in 30/31 outbreaks investigated giving an overall outbreak positive detection rate of 97%. At an individual patient level there was a positive diagnostic rate of 11.5% in a large hospital environment to 100% in smaller outbreak situations. The average patient positive rate was 34%. In addition we investigated 532 control faecal specimens from adults. Of these 530 were negative and 2 were repeatedly positive. CONCLUSIONS: It is essential that insensitive electronmicroscopy is replaced with the more sensitive reverse transcription PCR assays. These tests should be made available "on call" at weekends and public holidays. It is also important that outbreaks of NLV infection are monitored using sensitive RT-PCR assays so that the laboratory information can be used in ascertaining the spread and duration of the outbreak.  (+info)

Rapid and efficient extraction method for reverse transcription-PCR detection of hepatitis A and Norwalk-like viruses in shellfish. (2/790)

As part of an effort to develop a broadly applicable test for Norwalk-like viruses and hepatitis A virus (HAV) in shellfish, a rapid extraction method that is suitable for use with one-step reverse transcription (RT)-PCR-based detection methods was developed. The method involves virus extraction using a pH 9.5 glycine buffer, polyethylene glycol (PEG) precipitation, Tri-reagent, and purification of viral poly(A) RNA by using magnetic poly(dT) beads. This glycine-PEG-Tri-reagent-poly(dT) method can be performed in less than 8 h on hard-shell clams (Mercenaria mercenaria) and Eastern oysters (Crassostrea virginica) and, when coupled with RT-PCR-based detection, can yield results within 24 h. Observed sensitivities for seeded shellfish extracts are as low as 0.015 PFU of HAV and 22.4 RT-PCR50 units for Norwalk virus. Detection of HAV in live oysters experimentally exposed to contaminated seawater is also demonstrated. An adaptation of this method was used to identify HAV in imported clams (tentatively identified as Ruditapes philippinarum) implicated in an outbreak of food-borne viral illness. All of the required reagents are commercially available. This method should facilitate the implementation of RT-PCR testing of commercial shellfish.  (+info)

Characterization of capsid genes, expressed in the baculovirus system, of three new genetically distinct strains of "Norwalk-like viruses". (3/790)

"Norwalk-like viruses" (NLVs), members of a newly defined genus of the family Caliciviridae, are the most common agents of outbreaks of gastroenteritis in the United States. Two features of NLVs have hindered the development of simple methods for detection and determination of serotype: their genetic diversity and their inability to grow in cell culture. To assess the immune responses of patients involved in outbreaks of gastroenteritis resulting from infection with NLVs, we previously used recombinant-expressed capsid antigens representing four different genetic clusters, but this panel proved insufficient for detection of an immune response in many patients. To extend and further refine this panel, we expressed in baculovirus the capsid genes of three additional genetically distinct viruses, Burwash Landing virus (BLV), White River virus (WRV), and Florida virus. All three expressed proteins assembled into virus-like particles (VLPs) that contained a full-length 64-kDa protein, but both the BLV and WRV VLPs also contained a 58-kDa protein that resulted from deletion of 39 amino acids at the amino terminus. The purified VLPs were used to measure the immune responses in 403 patients involved in 37 outbreaks of acute gastroenteritis. A majority of patients demonstrated a fourfold rise in the titer of immunoglobulin G to the antigen homologous to the outbreak strain, but most seroconverted in response to other genetically distinct antigens as well, suggesting no clear pattern of type-specific immune response. Further study of the antigenicity of the NLVs by use of VLPs should allow us to design new detection systems with either broader reactivity or better specificity and to define the optimum panel of antigens required for routine screening of patient sera.  (+info)

Systemic, mucosal, and heterotypic immune induction in mice inoculated with Venezuelan equine encephalitis replicons expressing Norwalk virus-like particles. (4/790)

Norwalk-like viruses (NLVs) are a diverse group of single-stranded, nonenveloped, positive-polarity RNA viruses and are the leading cause of epidemic acute gastroenteritis in the United States. In this study, the major capsid gene of Norwalk virus, the prototype NLV, has been cloned and expressed in mammalian cells using a Venezuelan equine encephalitis (VEE) replicon expression system. Upon infection of baby hamster kidney (BHK) cells with VEE replicon particles (VRPs), the Norwalk virus capsid proteins self-assemble to generate high titers of Norwalk virus-like particles (VLPs) that are morphologically and antigenically analogous to wild-type Norwalk virus. Mice inoculated subcutaneously with VRPs expressing the Norwalk virus capsid protein (VRP-NV1) developed systemic and mucosal immune responses to Norwalk VLPs, as well as heterotypic antibody responses to the major capsid protein from another genogroup I NLV strain (NCFL) isolated from a recent outbreak. A second Norwalk virus capsid clone (NV2) containing three amino acid codon mutations from the NV1 clone was also expressed using VEE replicons (VRP-NV2), but upon infection of BHK cells failed to confer VLP self-assembly. Mice inoculated with VRP-NV2 elicited reduced systemic and mucosal immune responses to Norwalk VLPs, demonstrating the importance and potential utility of endogenous VLP presentation for maximum immune induction. Inoculation with either VRP-NV1 or VRP-NV2 resulted in serum antibody responses far superior to the induction in mice dosed orally with VLPs that were prepared using the VEE-NV1 replicon construct, a regimen similar to current models for NLV vaccination. Expression of NLV VLPs in mammalian cells offers a powerful approach for the design of novel NLV vaccines, either alone or in combination with current vaccination models.  (+info)

A predominant role for Norwalk-like viruses as agents of epidemic gastroenteritis in Maryland nursing homes for the elderly. (5/790)

Stool specimens from 156 Maryland nursing home residents, who became ill during 20 outbreaks of gastroenteritis from November 1987 through February 1988, were analyzed. All tested negative for astroviruses, enteroviruses, Group A rotaviruses, Sapporo-like caliciviruses, and enteric bacteria (i.e., Salmonella, Clostridium, and Shigella species). Eighty-two (52%) were positive for Norwalk-like viruses (NLVs), members of the family Caliciviridae. Six distinct genetic clusters within genogroups I and II of the NLVs were detected; a genogroup II (GII) virus closely related to the Camberwell virus in the NLV GII/4 genetic cluster was the predominant strain. Serologic evidence of infection with > or = 1 NLV was detected in 61 (56%) of 109 patients tested against 3 NLV antigens (i.e., Norwalk, Hawaii, and Toronto viruses). Sixteen (80%) outbreaks met the definition for an NLV outbreak. Taken together with a retrospective analysis of bacterial gastroenteritis in this same setting, these data support a major role for NLVs as etiologic agents of gastroenteritis in elderly persons.  (+info)

Identification of active-site amino acid residues in the Chiba virus 3C-like protease. (6/790)

The 3C-like protease of the Chiba virus, a Norwalk-like virus, is one of the chymotrypsin-like proteases. To identify active-site amino acid residues in this protease, 37 charged amino acid residues and a putative nucleophile, Cys139, within the GDCG sequence were individually replaced with Ala in the 3BC precursor, followed by expression in Escherichia coli, where the active 3C-like protease would cleave 3BC into 3B (VPg) and 3C (protease). Among 38 Ala mutants, 7 mutants (R8A, H30A, K88A, R89A, D138A, C139A, and H157A) completely or nearly completely lost the proteolytic activity. Cys139 was replaceable only with Ser, suggesting that an SH or OH group in the less bulky side chain was required for the side chain of the residue at position 139. His30, Arg89, and Asp138 could not be replaced with any other amino acids. Although Arg8 was also not replaceable for the 3B/3C cleavage and the 3C/3D cleavage, the N-terminal truncated mutant devoid of Arg8 significantly cleaved 3CD into 3C and 3D (polymerase), indicating that Arg8 itself was not directly involved in the proteolytic cleavage. As for position 88, a positively charged residue was required because the Arg mutant showed significant activity. As deduced by the X-ray structure of the hepatitis A virus 3C protease, Arg8, Lys88, and Arg89 are far away from the active site, and the side chain of Asp138 is directed away from the active site. Therefore, these are not catalytic residues. On the other hand, all of the mutants of His157 in the S1 specificity pocket tended to retain very slight activity, suggesting a decreased level of substrate recognition. These results, together with a sequence alignment with the picornavirus 3C proteases, indicate that His30 and Cys139 are active-site residues, forming a catalytic dyad without a carboxylate directly participating in the proteolysis.  (+info)

Waterborne outbreak of Norwalk-like virus gastroenteritis at a tourist resort, Italy. (7/790)

In July 2000, an outbreak of gastroenteritis occurred at a tourist resort in the Gulf of Taranto in southern Italy. Illness in 344 people, 69 of whom were staff members, met the case definition. Norwalk-like virus (NLV) was found in 22 of 28 stool specimens tested. The source of illness was likely contaminated drinking water, as environmental inspection identified a breakdown in the resort water system and tap water samples were contaminated with fecal bacteria. Attack rates were increased (51.4%) in staff members involved in water sports. Relative risks were significant only for exposure to beach showers and consuming drinks with ice. Although Italy has no surveillance system for nonbacterial gastroenteritis, no outbreak caused by NLV has been described previously in the country.  (+info)

Outbreak of acute gastroenteritis associated with Norwalk-like viruses among British military personnel--Afghanistan, May 2002. (8/790)

In the United States, Norwalk-like viruses (NLVs) cause an estimated 23 million episodes of illness, 50,000 hospitalizations, and 300 deaths each year. NLVs can be transmitted by fecally contaminated food and water and by direct person-to-person contact or through droplets of infected persons. Outbreaks of NLV-associated gastrointestinal illness are common in military settings. During May 13-19, 2002, a total of 29 British soldiers and staff of a field hospital in Afghanistan became acutely ill after a short incubation period with vomiting, diarrhea, and fever. This report summarizes the investigation of this outbreak and underscores the importance of the diagnostic capacity for NLVs.  (+info)

Human noroviruses are the most common cause of acute gastroenteritis worldwide and cause substantial levels of morbidity and mortality. Symptoms usually include acute onset of vomiting, abdominal cramps, and diarrhoea. Noroviruses are often associated with high-profile outbreaks in hospitals, nursing homes, cruise ships, and the military which cause significant economical burden. Noroviruses are also considered to be the most common viral agents of epidemic food-borne and water-borne viral gastroenteritis. Globally noroviruses are the cause of 18 % of all diarrhoeal diseases.. Due to the extreme infectivity of noroviruses, rapid and reliable laboratory diagnosis is critical to guide the control of norovirus outbreaks by choosing the most appropriate intervention and control practices.. GenomEra® Norovirus assay is rapid and easy to use qualitative in vitro diagnostic (IVD) nucleic acid test for the detection and differentiation of norovirus genogroups I and II from raw or unpreserved unformed ...
Presence of Norovirus in food can cause viral gasteroenteritis. Recently, lots of reports relating to Norovirus in food have been published. Special attention must be paid to the raw foods as they are not subjected to further heat treatment. In this study, pegaga, kesum, tauge and ulam raja (popular salad vegetables in Malaysia) were investigated for Norovirus. A total of 32 samples from each type of salad vegetables were purchased from local market and analyzed using One-step RT-PCR (Reverse Transcriptase-Polymerase Chain Reaction) for both genogroups namely Norovirus Genogroup I and Genogroup II. Results showed that tauge had the highest contamination with Norovirus Genogroup I (15.6%) comparing to pegaga (9.4%), kesum (12.5%) and ulam raja (0%). Samples were free from Norovirus Genogroup II. The study showed that raw vegetables are high-risk foods and can be contaminated with Norovirus.. ...
Noroviruses are the leading cause of foodborne illness in the United States. To better guide interventions, we analyzed 2,922 foodborne disease outbreaks for which norovirus was the suspected or confirmed cause, which had been reported to the Foodborne Disease Outbreak Surveillance System of the Centers for Disease Control and Prevention during 2001-2008. On average, 365 foodborne norovirus outbreaks were reported annually, resulting in an estimated 10,324 illnesses, 1,247 health care provider visits, 156 hospitalizations, and 1 death. In 364 outbreaks attributed to a single commodity, leafy vegetables (33%), fruits/nuts (16%), and mollusks (13%) were implicated most commonly. Infected food handlers were the source of 53% of outbreaks and may have contributed to 82% of outbreaks. Most foods were likely contaminated during preparation and service, except for mollusks, and occasionally, produce was contaminated during production and processing. Interventions to reduce the frequency of foodborne norovirus
This report highlights widespread increased frequency of norovirus-like illness outbreaks and ED visits during October--December 2006 and January--June 2007. This increase was associated with the emergence of two new cocirculating strains of norovirus GII.4. A previous increase in norovirus outbreaks in the United States also was associated with the emergence of new strains (7). Whether the increase in outbreaks is a result of increased pathogenicity or transmissibility of new strains, lower immunity in the population, or other factors is unclear. During late 2006 and early 2007, increases in AGE outbreaks consistent with norovirus (1) were reported by many state health departments. A high proportion of specimens tested were positive for norovirus, which suggests that the increase in AGE outbreaks was associated with norovirus infection. The magnitude and consistency of increases in multiple states suggest an actual increase rather than increased reporting resulting from increased awareness of ...
Control of norovirus outbreaks relies on enhanced hygiene measures, such as handwashing, surface cleaning, using disposable paper towels, and using separate toilets for sick and well persons. However, little is known about their effectiveness in limiting further spread of norovirus infections. We analyzed norovirus outbreaks in 7 camps at an international scouting jamboree in the Netherlands during 2004. Implementation of hygiene measures coincided with an 84.8% (95% predictive interval 81.2%-86.6%) reduction in reproduction number. This reduction was unexpectedly large but still below the reduction needed to contain a norovirus outbreak. Even more stringent control measures are required to break the chain of transmission of norovirus ...

From the Department of Environmental and Global Health.. Last week, the Emerging Pathogen Institutes Global Pathogens Laboratory had the privilege of hosting Dr. Jianrong Li of The Ohio State University. During his visit to The University of Florida, Dr. Li delivered a powerful, optimistic seminar titled New Interventions against Human Norovirus: Progress, Opportunities, and Challenges.. Human norovirus is a single-stranded positive-sense RNA virus of the family Caliciviridae responsible for more than 90% of nonbacterial gastroenteritis (stomach illness) worldwide and 60% of foodborne illness of a total 23 million cases in the United State every year. The primary difficulty in human norovirus research is the viruss inability to be grown in cell culture and the lack of a small animal model for pathogenesis study, which severely hampers research efforts to generate a vaccine.. To counter this, Dr. Lis group constructed a recombinant vesicular stomatitis virus (VSV) to express VP1, the major ...
The vaccine being tested in this study is called norovirus GI.1/GII.4 bivalent virus-like particle (VLP) vaccine adjuvanted with aluminum hydroxide and with or without monophosphoryl lipid A (MPL). The norovirus vaccine is being tested to assess different formulations of the vaccine that will then be further developed.. This study will look at the number of antibodies to norovirus formed in people who take different formulations of the norovirus vaccine. The study will enroll approximately 420 patients. Participants will be randomly assigned (by chance) to one of fourteen treatment groups-which will remain undisclosed to the patient and study doctor during the study (unless there is an urgent medical need).. All participants will receive a vaccination on Day 1 and Day 28 of the study. Some treatment arms will receive one dose of the norovirus vaccine and some arms will receive two. In order to keep the treatment arms undisclosed to the patient and the doctor, those randomized to the one dose ...
Attachment of human noroviruses to histo blood group antigens (HBGAs) is essential for infection, but how this binding event promotes the infection of host cells is unknown. Here, we employ protein NMR experiments supported by mass spectrometry and crystallography to study HBGA binding to the P-domain of a prevalent virus strain (GII.4). We report a highly selective transformation of asparagine 373, located in an antigenic loop adjoining the HBGA binding site, into an iso-aspartate residue. This spontaneous post-translational modification (PTM) proceeds with an estimated half-life of a few days at physiological temperatures, independent of the presence of HBGAs but dramatically affecting HBGA recognition. Sequence conservation and the surface-exposed position of this PTM suggest an important role in infection and immune recognition for many norovirus strains.. ...
No, its not a rampaging bird flu, but the norovirus is a highly contagious gastrointestinal virus. This virus affects 21 million people each year in the U.S. and it is now stalking two of the nations favorite national parks: Yellowstone and Grand Teton. Norovirus common to crowded areas Symptoms of a norovirus infection include nausea, vomiting, and diarrhea. These symptoms will appear within 48 hours of exposure and generally will last a few days and then clear up without any treatment besides bed rest and plenty of fluids. According to the Mayo Clinic, Noroviruses commonly spread through food or water contaminated by fecal matter during preparation. You can also acquire norovirus infection through close contact with an infected person. These viruses are especially common in crowded areas, like day cares, cruise ships, and hospitals. Infected employees quarantined So far, between the two parks, 150 employees and 50 guests have been diagnosed with norovirus. To prevent further spread, ...
Special to the Sydenham Current. Norovirus is a virus that causes gastroenteritis.. It can be commonly referred to as winter vomiting disease or the stomach flu.. Using the term stomach flu is misleading in that having norovirus is unrelated to the influenza virus that causes respiratory illness and is generally called the flu.. Symptoms of norovirus include sudden onset of vomiting, diarrhea, nausea, low grade fever and abdominal cramps.. Norovirus is a common virus and affects all age groups of people.. However, young children, the elderly, and those with underlying medical conditions tend to experience more severe symptoms.. It is transmitted by contaminated food and water, person to person direct contact and contact with contaminated surfaces.. Most foodborne outbreaks occur when an infected food handler contaminates the food being served.. Shellfish harvested from contaminated water can also transmit norovirus..

Previous studies and empirical evidence suggest norovirus outbreaks in California exhibit correlation with environmental variables and exhibit spatial spread patterns. Few studies have been done looking at what causes norovirus seasonality in temperate climates and more research is needed on the regional level. This study aims to find what relationships exist with outbreak occurrence and environmental variables in California, as well as any spatial patterns of spread or clustering of outbreaks. Spatial analysis tools were used to find any relationships between California norovirus outbreak data and environmental variables. The results showed a south to north spread of outbreaks in California and potential correlation with outbreaks and lower temperatures and higher relative humidity. More research is needed to substantiate the correlation with outbreaks and environmental variables.
Because secondary transmission masks the connection between sources and outbreaks, estimating the proportion of foodborne norovirus infections is difficult. We studied whether norovirus genotype frequency distributions (genotype profiles) can enhance detection of the sources of foodborne outbreaks. Control measures differ substantially; therefore, differentiating this transmission mode from person-borne or food handler-borne outbreaks is of public health interest. Comparison of bivalve mollusks collected during monitoring (n = 295) and outbreak surveillance strains (n = 2,858) showed 2 distinguishable genotype profiles in 1) human feces and 2) source-contaminated food and bivalve mollusks; genotypes I.2 and I.4 were more frequently detected in foodborne outbreaks. Overall, ≈21% of all outbreaks were foodborne; further analysis showed that 25% of the outbreaks reported as food handler-associated were probably caused by source contamination of the food.
Illustration of Norovirus invading a dendritic cell (lower left) in the small intestine. Noroviruses are a genus of single-stranded RNA, non-enveloped viruses in the Caliciviridae family. The viruses are transmitted by fecally-contaminated food or water; by person-to-person contact; and through the air with subsequent contamination of surfaces. Noroviruses are the most common cause of viral gastroenteritis in humans, and affect people of all ages. Very little is known about the life cycle of Norovirus because they are so difficult to culture under laboratory conditions. Investigation of murine norovirus (MNV-1) in mice has shed some light on the human version. MNV-1 has an affinity for macrophage and dendritic cells. The replication process appears to occur within clusters of vesicles, their membranes and proteins derived from different sources including the endoplasmic reticulum, trans-Golgi apparatus, and endosomes.

Norovirus is a highly contagious viral illness that often goes by other names, such as viral gastroenteritis, stomach flu, and food poisoning.. The symptoms include nausea, vomiting, diarrhea, and some stomach cramping. Sometimes people additionally have a low-grade fever, chills, headache, muscle aches, and a general sense of tiredness. The illness often begins suddenly, and the infected person may feel very sick. In most people, the illness is self-limiting with symptoms lasting for about 1 or 2 days. In general, children experience more vomiting than adults do.. Norovirus is spread person to person particularly in crowded, closed places. Norovirus is typically spread through contaminated food and water, touching surfaces or objects contaminated with norovirus and then putting your hand or fingers in your mouth and close contact with someone who is vomiting or hasdiarrhea.. Norovirus causes more than 20 million illnesses annually, and it is the leading cause of gastroenteritis outbreaks in the ...
With the recent outbreaks of Norovirus causing school closures in the US, the Centers for Disease Control & Prevention has published guidelines including the recommendation of cleaning and disinfecting contaminated surfaces with a disinfectant registered as effective against Norovirus by the Environmental Protection Agency.. In addition to Norovirus outbreaks in schools, the CDC has recommended in its Vessel Sanitation Operations Manual the use of a halogen-based disinfectant and sanitiser for cleanup and disinfection of contaminated areas in cruise ships.. Performacide hard surface disinfectant is EPA registered for killing Norovirus in schools, cafeterias, colleges, daycare centres, hotels, and public eating places. It utilises activated chlorine dioxide, a halogen-based EPA registered disinfectant that is effective against Norovirus.. The product is perfect for disinfecting hard non-porous surfaces after contamination by fecal and vomit accidents. Having many versatile applications, it can ...
No-one wants a vomiting bug as a Christmas present, but each winter many people unintentionally bring Norovirus into hospitals and care home when visiting loved ones.. With less than a week to go until Christmas Day Bath and North East Somerset Council is urging people to protect themselves and their loved ones against the winter vomiting bug, Norovirus, by taking simple steps to stop the spread of the virus, particularly to vulnerable people.. Norovirus is a highly contagious stomach bug that causes diarrhoea and vomiting. Most people will recover within a few days and can return to work or school. However if Norovirus is introduced unintentionally into care homes and hospitals by visitors it can cause chaos, leading to ward closures and making it difficult for health care workers to treat vulnerable patients at the busiest time of the year.. When a hospital ward is classed as closed due to a Norovirus outbreak it means that the ward is closed to visitors and no further patients can be ...
Norovirus is known to cause gastroenteritis outbreaks worldwide. It is a hardy viruses that can be quite stable in the environment, making it difficult to eliminate. While, Norovirus is primarily transmitted via the fecal-oral route, environmental transmission is particularly important in health care facilities. In 2004, the Johns Hopkins Hospital noted a significant Norovirus outbreak at its 946-bed tertiary care hospital in Baltimore.
Winter vomiting disease is caused by norovirus (NoV) and affects millions of people every year resulting in 200.000 deaths among children in developing countries. It was observed early that not all individuals exposed to the norovirus became ill. The reason for this is now recognized to be dependent upon the secretor status of an individual. The secretor status determines the ability of an individual to express histo-blood group antigens (HBGA) on mucosa and in saliva. A non-secretor is unable to express HBGAs due to a mutation in a gene called FUT2. In this thesis, I have investigated the antibody prevalence and titer in humans in Sweden and Nicaragua to the most common GII NoV and the correlation to secretor status, Lewis status and ABO. I found that secretors had significantly higher antibody prevalence and titer to GII NoV than non-secretors suggesting that non-secretors are less prone to be infected by the GII NoV. In Nicaragua, I also found several different NoV strains circulating at the ...
Although norovirus is the most common cause of gastroenteritis, there are few data on the community incidence of infection/disease or the patterns of acquired immunity or innate resistance to norovirus.,We followed a community-based birth cohort of 194 children in Ecuador with the aim to estimate (1) the incidence of norovirus gastroenteritis from birth to age 3 years, (2) the protective effect of norovirus infection against subsequent infection/disease, and (3) the association of infection and disease with FUT2 secretor status.,Over the 3-year period, we detected a mean of 2.26 diarrheal episodes per child (range, 0-12 episodes). Norovirus was detected in 260 samples (18%) but was not found more frequently in diarrheal samples (79 of 438 [18%]), compared with diarrhea-free samples (181 of 1016 [18%]; P = .919). A total of 66% of children had at least 1 norovirus infection during the first 3 years of life, and 40% of children had 2 infections. Previous norovirus infections were not associated ...
Norovirus is a seriously contagious virus that can infect anyone, according to Centers for Disease Control. You can get it from an infected person, contaminated food or water, or by touching contaminated surfaces. Additionally, ample research says it can be transmitted through the air. The virus causes your stomach or intestines or both to get inflamed. This leads you to have stomach pain, nausea, and diarrhea and to throw up. These symptoms can be serious for some people, especially young children and older adults, the most vulnerable among us.. Norovirus can have significant economic impact, too. Global Economic Burden of Norovirus Gastroenteritis is a study at PLOS One that developed a computational simulation model to estimate the economic burden of Norovirus in every country/area (233 total) stratified by World Health Organization region and globally, from the health system and societal perspectives. We considered direct costs of illness (e.g., clinic visits and hospitalization) and ...
GII.4 noroviruses are a major cause of acute gastroenteritis in humans. A new variant of GII.4, the 2008 variant, has recently increased its prevalence on a global scale. A previous study of this variant in Japan suggested that it might be of recombinant origin, with a breakpoint at the ORF1-ORF2 junction. Here, examination of the evolutionary origin of the 2008 variant based on a larger sample of worldwide GII.4 norovirus sequences revealed a more complex pattern of recombination between the 2006a- and 2006b-like variants of genotype GII.4, involving the P2 antigenic domain. Double (termed 2008i) and triple (termed 2008ii) recombinant forms of 2008 variants were identified. This study highlights the possible importance of intra-genotypic recombination over antigenic regions in driving norovirus evolution, and is suggestive of a process analogous to the antigenic shift of influenza A virus by reassortment.
The objective of this study was to characterize the inactivation effects of a pilot-scale continuous-flow intense pulsed light (IPL) system on microorganisms in untreated groundwater used in the food industry. The inactivation effects of laboratory- and pilot-scale IPL systems on murine norovirus (MNV), a human norovirus surrogate, were also investigated. Flow rates of 40, 32, 20 and 12 l/min were tested (corresponding to 89,113, 179, and 290 s of treatment time in a chamber, respectively). A 290-s pilot-scale IPL treatment at an energy dose of 14.02 J/cm(2) resulted in a 4.79-log reduction of Escherichia coli C600 in water with an initial count of 10(5)-10(6) CFU/ml, while a 270-s treatment at an energy dose of 13.05 J/cm(2) resulted in a 2.91-log inactivation of aerobic and facultative anaerobic heterotrophs in untreated groundwater with the initial count of 4.5 x 10(4) CFU/ml. An 89-s treatment at a dose of 4.30 J/cm(2) resulted in a 3.35-log inactivation of MNV in water with the initial ...

Winter is the season for influenza, and as the flu season continues, State health officials want to remind Hoosiers this is also norovirus or stomach flu season. Norovirus is not actually influenza, however, both may be prevented by taking measures to protect yourself. This season, health officials are reporting that a new strain of norovirus has appeared. This new strain, called GII.4 Sydney, originated in Australia and has been detected throughout Europe and the United States. This strain is overtaking others to become the dominant strain in areas where it has been found. Most people will be susceptible to this new strain; however, it does not carry worse symptoms than others.. Health officials confirm the new GII.4 Sydney strain of norovirus has reached Indiana and say they will continue to investigate outbreaks and monitor disease activity.. With so much discussion regarding this flu season, it is important for Hoosiers to understand there is a difference between influenza and what is ...
Noroviruses cause the majority of epidemic outbreaks of acute viral gastroenteritis worldwide. Human norovirus strains do not grow in cell culture, but recent carbohydrate binding, sequence and structural analyses have begun to define functional domains in the norovirus capsid that may be conserved among multiple antigenic types. The purpose of this study was to localize domains and define sequences in the major capsid protein VP1 that are important for cell interactions. Monoclonal antibodies to genogroups GI.1 and GII.2 reference strains Norwalk virus and Snow Mountain virus, respectively, were generated that blocked binding of recombinant virus-like particles to Caco-2 intestinal cells and inhibited haemagglutination. Peptides that mimicked the mAb binding epitopes were selected from a phage-displayed random nonapeptide library. Anti-recombinant Norwalk virus mAb 54.6 and anti-recombinant Snow Mountain virus mAb 61.21 recognized epitopes located in the protruding P2 domain of VP1. The epitope
Noroviruses are the most well-known reason for intense gastroenteritis, which causes looseness of the bowels, stomachache, queasiness, and spewing.. Norovirus is an exceptionally infectious infection that causes an aggravation or contamination of the stomach and digestion tracts, regularly called intense gastroenteritis.. Truth be told, noroviruses are the most widely recognized reason for intense gastroenteritis in the United States, bringing about 19 to 21 million ailments, 56,000 to 71,000 hospitalizations, and 570 to 800 passings every year, as per the Centers for Disease Control and Prevention (CDC).. Norovirus Outbreaks. Noroviruses, of which there are various sorts, are effortlessly transmitted between individuals along the fecal-oral course.. That is, the infections are available in the stool of tainted individuals, and are spread by:. Ingesting debased sustenance or fluids.

Human noroviruses (NoVs), a major cause of viral gastroenteritis, are difficult to study due to the lack of a cell-culture and a small-animal model. Pigs share with humans the types A and H histo-blood group antigens on the intestinal epithelium and have been suggested as a potential model for studies of NoV pathogenesis, immunity and vaccines. In this study, the effects of age and a cholesterol-lowering drug, simvastatin, on the susceptibility of pigs to NoV infection were evaluated. The median infectious dose (ID50) of a genogroup II, genotype 4 (GII.4) 2006b variant was determined. The ID50 in neonatal (4-5 days of age) pigs was ≤2.74×103 viral RNA copies. In older pigs (33-34 days of age), the ID50 was 6.43×104 but decreased to |2.74×103 in simvastatin-fed older pigs. Evidence of NoV infection was obtained by increased virus load in the intestinal contents, cytopathological changes in the small intestine, including irregular microvilli, necrosis and apoptosis, and detection of viral antigen in
en] Bovine noroviruses belong to the family Caliciviridae, genus Norovirus. Two genotypes are described and viruses genetically related to the Jena and Newbury-2 strains are classified into genotypes 1 and 2 respectively. In this study, virus-like particles (VLP) of the previously detected B309 Belgian strain, genetically related to genotype 2 bovine noroviruses, were used to investigate virus-host interactions in vitro. B309 VLP were shown to bind to several bovine cell lines. This binding was not affected by heparinase or chondroitinase treatment but was significantly inhibited by both sodium periodate, alpha-galactosidase, trypsin and phospholipase C treatment. Cell treatment by neuraminidase also moderately affected this binding. Taken together, these results show that, in addition to a galactosyl residue, sialic acid could also be involved in binding to susceptible cells. In addition, both the cholesterol-dependent pathway and macropinocytosis are used for B309 VLP internalisation by ...

Norovirus is a group of highly contagious viruses that cause short-term gastroenteritis symptoms including nausea, vomiting, diarrhoea, and potentially chills and fever. Norovirus infection can occur by contact with a person carrying the virus, touching or using contaminated surfaces (e.g., door knobs, light switches, utensils), food or drinking water. Infections are more common in winter as colder temperatures favour virus survival. Most individuals who become ill recover in 1 - 2 days without needing medical treatment; however, dehydration can be a serious side-effect, especially for young children, the elderly, pregnant women, and those with compromised immune systems.. Norovirus outbreaks are typically associated with long-term care facilities, daycares, cruise ships, or other public places where people are in proximity to one another. The resources listed here are intended to assist public health practitioners, food handlers, and health care providers to 1) quickly access resources on ...

At the recent Canadian University Press national conference in Victoria, Canada, more than one third of the 370 attendees were struck with norovirus.. According to USA Today, 165 conference attendees and Harbour Towers Hotel and Suites staff members fell ill. As norovirus is extremely contagious, sick attendees remained isolated in their hotel rooms until they were well enough to travel. Fortunately for them, fees for flight changes and rooms were waived.. The general manager of the hotel informed the Victoria Times Colonist, a local paper, that the hotel has been through a thorough cleaning and that employees will continue to wipe down surfaces with bleach to make sure nothing is lingering.. Noroviruses cause acute gastroenteritis (vomiting, stomach pain, and diarrhea) in humans. Noroviruses are commonly known as stomach flu or food poisoning. This group of viruses can be spread from person to person, through food and water, and through fomites (any inanimate object that has the ability ...

Chipotle CEO Steve Ells said we believe someone was working while sick. In response, employees will undergo relentless training to make sure everyone understands that they cant work if they are sick.. The outbreak is a reminder of 2015, the year hundreds of Chipotle customers were sickened in multiple outbreaks of E. coli, Salmonella, and norovirus at multiple restaurant locations.. In September 2016, Chipotle said it had paid lawsuit settlements to nearly 100 people who were sickened with food poisoning in those outbreaks.. Norovirus (sometimes called the stomach flu) is one of the most common causes of food poisoning outbreaks. People who are infected with norovirus usually develop symptoms within 12 to 48 hours after eating contaminated food, and most people get better in 1 to 3 days.. ...
Vermonts own Department of Health even weighed in on the virus, while a Middlebury Campus article takes pity on Wes and quotes from our own medical director, Davis Smith, who suggests (probably not incorrectly) that Superbowl parties were to blame. (Can someone prepare a survey on norovirus prevalence vs. Superbowl party attendance? Please?) It also mentions Williams, where gastro cases were observed, but not nearly so severe.. Even more alarmingly, Princeton has apparently seen the worst norovirus outbreak in 10 years, affecting at least 190 students, with another 44 hospitalizations reported at nearby Rider University. (Whoah.). The worst thing Ive read,though? Norovirus hit three cruise ships a few weeks ago, delaying the departure of the luxurious Voyager of the Seas in New Orleans. Remember, kids: the only thing worse than spending eight hours doubled over vomiting in a dimly lit Butts bathroom is spending eight hours doubled over vomiting while bouncing along the the New Orleans coast ...
Background: Laboratory- confirmed norovirus illness is reportable in Germany since 2001. Reported case numbers are known to be undercounts, and a valid estimate of the actual incidence in Germany does not exist. An increase of reported norovirus illness was observed simultaneously to a large outbreak of Shiga toxin-producing E. coli O104: H4 in Germany in 2011 - likely due to enhanced (but not complete) awareness of diarrhoea at that time. We aimed at estimating age- and sex-specific factors of that excess, which should be interpretable as (minimal) under-reporting factors of norovirus illness in Germany. Methods: We used national reporting data on laboratory-confirmed norovirus illness in Germany from calendar week 31 in 2003 through calendar week 30 in 2012. A negative binomial time series regression model was used to describe the weekly counts in 8.2 age- sex strata while adjusting for secular trend and seasonality. Overall as well as age- and sex- specific factors for the excess were ...

Norovirus (NoV) constitutes the second most common viral pathogen causing pediatric diarrhea after rotavirus. In Africa, diarrhea is a major health problem in children, and yet few studies have been performed regarding NoV. The association of histo-blood group antigens (HBGA) and susceptibility to NoV infection is well established in Caucasian populations with non-secretors being resistant to many common NoV strains. No study regarding HBGA and NoV susceptibility has yet been performed in Africa. We collected 309 stool and 208 saliva samples from diarrheal children in Ouagadougou, Burkina Faso; May 2009 to March 2010. NoV was detected using real-time PCR, and genotyped by sequencing. Saliva samples were ABO, Lewis and secretor phenotyped using in house ELISA assays. NoV was detected in 12% (n = 37) of the samples. The genotype diversity was unusually large; overall the 37 positive samples belonged to 14 genotypes. Only children ,2 years of age were NoV positive and the GII.4 NoVs were more ...
Southeast Idaho health officials say there has been nine confirmed cases of norovirus identified in Southeast Idaho since Jan. 1. This number surpasses the total annual number of confirmed cases in both 2013 and 2014. While there were nine confirmed cases, Ian Troester-Solbrig, a registered nurse and epidemiologist for Southeastern Idaho Public Health, said he has treated some 50 people suffering from norovirus-like symptoms this year.. In addition, at least one person recently died from dehydration, a complication of the viral disease.. Norovirus is a highly contagious viral illness that often goes by other names, such as viral gastroenteritis, stomach flu, and food poisoning.. The symptoms include nausea, vomiting, diarrhea, and some stomach cramping. Sometimes people additionally have a low-grade fever, chills, headache, muscle aches, and a general sense of tiredness. The illness often begins suddenly, and the infected person may feel very sick. In most people, the illness is self-limiting ...
Noroviruses in the Caliciviridae are a major cause of acute gastroenteritis in all age groups. The illness occurs often in settings where people are in close contact, such as families, nursing homes, hospitals, schools, camps, cruise ships, military barracks, and social gatherings. In most individuals, norovirus gastroenteritis (known commonly as stomach flu) resolves in two to three days. However, in patients with underlying conditions such as immunosuppression or in the very old and young, the illness can become life-threatening. There are presently no approved vaccines or specific antiviral drugs for the noroviruses, and the overall goal of this research program is to advance their development.. One of the major specific areas of research in our laboratory is to develop experimental systems in which to study norovirus replication and immunity. The inability to grow the human noroviruses associated with acute gastroenteritis has been a major research obstacle. We have conducted comparative ...
Norovirus (NoV) is a major cause of epidemic gastroenteritis in industrialized countries, yet the epidemiological significance of NoV in industrializing countries remains poorly understood. The spatiotemporal distribution of NoV genotypes identified in 2054 enrolled children was investigated between May 2009 and December 2010, in Ho Chi Minh City (HCMC), Vietnam. A total of 315 NoV extracted from stool samples were genotyped and GPS mapped to their source. Genogroup II NoV, particularly GII.4, were predominant, and the GII.4 strains could be subgrouped into GII.4-2006b (Minerva) and GII.4-2010 (New Orleans) variants. There was no spatiotemporal structure among the endemic GII strains; yet a significant spatiotemporal signal corresponding with the novel introduction of GII.4-2010 variant was detected. These data show that NoV GII.4 variants are highly endemic in HCMC and describe a scenario of rapid NoV strain replacement occurring in HCMC in early 2010 ...

Human noroviruses (HuNoVs) are the leading cause of epidemic gastroenteritis worldwide. Study of HuNoV biology has been hampered by the lack of an efficient cell culture system. Recently, enteric commensal bacteria Enterobacter cloacae has been recognized as a helper in HuNoV infection of B cells in vitro. To test the influences of E. cloacae on HuNoV infectivity and to determine whether HuNoV infects B cells in vivo, we colonized gnotobiotic pigs with E. cloacae and inoculated pigs with 2.74 × 10(4) genome copies of HuNoV. Compared to control pigs, reduced HuNoV shedding was observed in E. cloacae colonized pigs, characterized by significantly shorter duration of shedding in post-inoculation day 10 subgroup and lower cumulative shedding and peak shedding in individual pigs. Colonization of E. cloacae also reduced HuNoV titers in intestinal tissues and in blood. In both control and E. cloacae colonized pigs, HuNoV infection of enterocytes was confirmed, however infection of B cells was not ...
Everyone hates the norovirus, with the exception of two distinct groups. First: scientists. Professor Ian Goodfellow, who has spent the past decade studying it, has lovingly dubbed the norovirus the Ferrari of the virus world, not because it makes the contents of your stomach accelerate from 0-60 in 3.4 seconds, but because its so ruthlessly efficient. Requiring a mere 20 particles to seize command of its victims, the norovirus is 200 times more infectious than Daydream Believer by The Monkees. Consequently many scientists claim to be impressed by the thing ? a bit like admiring Nazi architecture, if you ask me.. It must be brilliant being a scientist during an outbreak like this because if you get infected yourself, you can at least take the edge off your suffering by admiring the sheer force of your symptoms. The fascinating pitter-patter of stomach contents against the back of your teeth as a fearsome torrent of spew erupts from within like a liquid poltergeist fleeing an exorcism. The ...

Virus entry depends on biomolecular recognition at the surface of cell membranes. In the case of glycolipid receptors, these events are expected to be influenced by how the glycan epitope close to the membrane is presented to the virus. This presentation of membrane associated glycans is more restricted than that of glycans in solution, particularly because of orientational constraints imposed on the glycolipid through its lateral interactions with other membrane lipids and proteins. We have developed and employed a total internal reflection fluorescence microscopy-based binding assay and. a scheme for molecular dynamics (MD) membrane simulations to investigate the consequences of various glycan presentation effects. The system studied was histo-blood group antigen (HBGA) epitopes of membrane-bound glycosphingolipids (GSLs) derived from small intestinal epithelium of humans (type 1 chain) and dogs (type 2 chain) interacting with GII.4 norovirus-like particles. Our experimental results showed ...
Norovirus is often transmitted from person-to-person. Transmission may also be food-borne, but only few norovirus outbreak investigations have identified food items as likely vehicles of norovirus transmission through an analytical epidemiological study. During 7-9 January, 2009, 36 persons at a military base in Germany fell ill with acute gastroenteritis. Food from the military bases canteen was suspected as vehicle of infection, norovirus as the pathogen causing the illnesses. An investigation was initiated to describe the outbreaks extent, to verify the pathogen, and to identify modes of transmission and source of infection to prevent further cases. For descriptive analysis, ill persons were defined as members of the military base with acute onset of diarrhoea or vomiting between 24 December 2008, and 3 February 2009, without detection of a pathogen other than norovirus in stools. We conducted a retrospective cohort study within the headquarters company. Cases were military base members with onset
Uncooked oysters from Canadas Pacific Coast have been confirmed as the source of a norovirus outbreak. according to the British Columbia Center for Disease Control.. Oysters making people ill have been traced to a section of Effingham Inlet on Vancouver Islands west coast. The oysters were harvested between Sept. 7 and Sept. 21.. Because of the outbreak, the Canadian Food Inspection Agency (CFIA) issued an expanded warning about eating oysters. The public warning originally included Evening Cover Oysters Processing of Nanaimo, B.C. It was expanded to include Albion Fisheries of Victoria, Albion Fisheries of Vancouver, Pacific Rim Shellfish of Vancouver and Sea World Fisheries of Vancouver.. BCs Center for Disease Control reports that at least three clusters of norovirus in the Vancouver area are related to eating uncooked oysters from Effingham Inlet.. Canadian officials did not say how many people have come down with symptoms of the virus, which include nausea, vomiting, diarrhea and stomach ...
Norovirus infection and illness are increasingly used as end-points in sewage-related health risk assessments, especially as data from clinical trials outbreak studies have recently become available. The authors of a very recent clinical trial have inferred that the human median infectious dose is higher than previous estimates and similar to that of other RNA viruses. This finding has the potential to cause a revision of previous risk assessments. However, in reaching this conclusion, the potential role of aggregation of these viruses seems not to have been accounted for, although it was accounted for in an earlier trial. In fitting (hypergeometric) dose-response curves to data from Norovirus clinical trials, the potential for the laboratory-stored stock of this non-culturable virus to have become aggregated onto storage matrix substances, as observed in a clinical trial, must be addressed. That is because standard dilution series calculations for doses are based on the assumption of uniform mixing of
Norovirus and sapovirus are major agents of gastroenteritis and the first cause of foodborne gastroenteritis worldwide. Elucidation of the replication mechanisms underlying replication of those important pathogens may lay the ground stone for a comprehensive development of antiviral strategies targeting the replication complex. In this project, the interaction of the replication enzymes with the viral genome will be investigated. In a fist step, a bioinformatics screen for regulatory RNA elements will be performed. This screen will encompass the entire genome of prototype strains in the norovirus and sapovirus. Strongly structured RNA sequences will then be mapped in the viral genome. In a further experimental step, the interaction of the sequences with the viral enzymes will be addressed. This experimental step will occur in vitro using recombinant viral enzymes as well as synthetic RNA corresponding to the viral sequences identified. The interaction will be assessed with Plasmon resonance a ...
Interpretive Summary: Human histo-blood group antigens (HBGA) have been identified previously as candidate receptors for human norovirus (NOR). HBGAs of blood group types A, H1 (related to O type), and Lewis have been identified as the major types that bind NOR. We have identified that pig stomach (gastric) mucin (PGM) also contains blood group A, H1, and Lewis (Lewis type b) HBGAs and binds more strains of NOR than do specific antibodies to NOR. NOR strains representing the I and II genogroups and present in dilute samples could be captured and concentrated by PGM-conjugated to magnetic beads, and NOR on beads were available for further processing. NOR present in a human patient fecal sample was detectable at a dilution of 1: 1,000,000 using the standard protocol RNA extraction procedure, whereas, NOR was detectable at a 1: 100,000,000 dilution due to efficient capture and concentration of NOR by PGM-beads. Moreover, NOR present in spiked complex food samples (e.g. oyster extract, strawberry, ...
Noroviruses (family Caliciviridae) are the primary cause of viral gastroenteritis worldwide. The virus is highly infectious and touching contaminated surfaces can contribute to infection spread. Although the virus was identified over 40 years ago the lack of methods to assess infectivity has hampered the study of the human pathogen. Recently the murine virus, MNV-1, has successfully been used as a close surrogate. Copper alloys have previously been shown to be effective antimicrobial surfaces against a range of bacteria and fungi. We now report rapid inactivation of murine norovirus on alloys, containing over 60% copper, at room temperature but no reduction of infectivity on stainless steel dry surfaces in simulated wet fomite and dry touch contamination. The rate of inactivation was initially very rapid and proportional to copper content of alloy tested. Viral inactivation was not as rapid on brass as previously observed for bacteria but copper-nickel alloy was very effective. The use of chelators and
Noroviruses (family Caliciviridae) are the primary cause of viral gastroenteritis worldwide. The virus is highly infectious and touching contaminated surfaces can contribute to infection spread. Although the virus was identified over 40 years ago the lack of methods to assess infectivity has hampered the study of the human pathogen.

Studies have shown that norovirus can survive on fomite surfaces for up to 12 days and that routine cleaning, without a disinfectant specifically to address norovirus, may be ineffective in eliminating its presence on fomite surfaces and can even serve as a means of spreading the virus to other fomites.(7, See Attached References) Noroviruses are the most common cause of sporadic cases and outbreaks of acute gastroenteritis (AGE) and transmission occurs via foodborne and person-to-person routes, airborne inhalation of vomitus droplets, and also through contact with contaminated environmental surfaces.(3) Food employees exposed to vomitus are at risk of contracting norovirus illness and can subsequently transfer the virus to ready-to-eat food items served to consumers.. Clean up of norovirus is different from routine cleaning and sanitizing and involves a more stringent cleaning and disinfecting process. For example, quaternary ammonium compounds are often used for routinely sanitizing food ...

Food Safety Focus (1st Issue, August 2006) - Food Incident Highlight. New Zealand Food Safety Authority (NZFSA) Advised the Public not to Consume Uncooked Oysters Imported from Korea. The NZFSA issued a reminder to the public on 6 July 2006 of not to consume uncooked oysters imported from Korea. The statement was made in response to several reported outbreaks in New Zealand that had been linked to the consumption of uncooked Korean oysters. Although all bags of frozen Korean oysters were clearly labelled as requiring cooking before consumption, this practice has not been consistently observed by the catering industry in New Zealand. Raw oysters are known to sometimes carry norovirus, which can cause gastrointestinal illness. Norovirus is commonly found in sewage-contaminated water. Ingestion of raw or inadequately cooked foods, including shellfish, salad and raw vegetables can pose a high risk of norovirus infection. Symptoms caused by norovirus may include nausea, vomiting, non-bloody diarrhoea ...
Noroviruses cause between 19 million and 21 million cases of acute gastroenteritis in the U.S. each year, according to the Centers for Disease Control and Prevention (CDC).

Norovirus is the leading cause of severe gastroenteritis in children in the United States, according to a new study in the New England Journal of Medicine.
Officials may never be able to definitively determine the cause of the outbreak, which prompted OHara Catholic School in Eugene, Oregon, to cancel three days of classes.. But Lane County Public Health spokesman Jason Davis said testing shows that at least 10 students and others who attended an event in which a master carver whittled a face into a massive pumpkin were infected with the virus.. The virus may also have spread at a breakfast for school staff and at other gatherings, Davis said.. The disease, which has a long lifespan, spreads from an infected person, contaminated food or water, or by touching contaminated surfaces, meaning that a student who did not wash his hands could have spread it to others at the gathering, Davis said.. The virus causes the stomach or intestines or both to become inflamed, called acute gastroenteritis, which leads to stomach pain, nausea, and diarrhea, according to the Centers for Disease Control and Prevention.. ...
Human norovirus may not grab the headlines that bacterial illnesses tied to produce do, but the virus likely is responsible for up to 40 percent of all foodborne outbreaks. As part of a two-year study, Dr. Melissa K. Jones, a research assistant professor with the University of Florida, Gainesville, is looking at characteristics of irrigation water and how they relate to norovirus survival in the water, on produce and transmission to a host.. Were kind of on the leading edge of it, said Jones, who will present her findings during the CPS Produce Research Symposium, June 23 - 24, in Atlanta. One of the things were learning about norovirus is they have a really high presence in the environment. And weve known for a long time that they are very, very stable and can survive for years in the water and the soil.. Joining her in the project are experts in food safety, foodborne disease and noroviruses. Jones credited Dr. Keith Schneider, a University of Florida professor specializing in produce ...

Its that time of year - everyone seems to be sick with one sort of illness or another - flu, colds, strep throat, and Norovirus (the stomach bug), to name a few.. Frequent hand washing is very important in the prevention of these illnesses. Wash your hands after being out in public, after caring for a sick family member (wiping your little ones nose), after using the rest room and especially before you eat. If you are the one who is sick, wash your hands after covering your cough, blowing your nose, and after any vomiting or diarrhea incidents. You dont have to use antibacterial soap; any soap will do. However, you do need to wash for at least 20 seconds - its the friction of washing that gets the bacteria and viruses off. If people in your house are sick, consider switching to paper towels for drying your hands, so you dont recontaminate them on a common towel that everyone has been using. Hand sanitizers are good in a pinch, if you cant wash your hands, but they may not be effective ...
