Since 2004, the Pan American Health Organization (PAHO) has carried out rotavirus surveillance in Latin America and the Caribbean. Here we report the characterization of human rotavirus with the novel G-P combination of G4P[14], detected through PAHO surveillance in Barbados. Full genome sequencing of strain RVA/Human-wt/BRB/CDC1133/2012/G4P[14] revealed that its genotype is G4-P[14]-I1-R1-C1-M1-A8-N1-T1-E1-H1. The possession of a Genogroup 1 (Wa-like) backbone distinguishes this strain from other P[14] rotavirus strains. Phylogenetic analyses suggested that this strain was likely generated by genetic reassortment between human, porcine and possibly other animal rotavirus strains and identified 7 lineages within the P[14] genotype. The results of this study reinforce the potential role of interspecies transmission in generating human rotavirus diversity through reassortment. Continued surveillance is important to determine if rotavirus vaccines will protect against strains that express the P[14] ...
Two oral rotavirus vaccines are available in Australia, and their efficacy and safety in the prevention of rotavirus gastroenteritis have been extensively evaluated.33-39 Both are live attenuated vaccines administered orally to infants, but the component vaccine viruses differ. The human rotavirus vaccine, Rotarix (GlaxoSmithKline), is a live attenuated vaccine containing one strain of attenuated human rotavirus (G1P1A[8] strain). Rotarix protects against non-G1 serotypes on the basis of other shared epitopes. A pentavalent vaccine, RotaTeq (CSL Limited/Merck & Co Inc), contains five human-bovine rotavirus reassortants with the human serotypes G1, G2, G3, G4 and P1A[8] and the bovine serotypes G6 and P7.. In middle- and high-income countries, a course of vaccination with either Rotarix or RotaTeq prevents rotavirus gastroenteritis of any severity in approximately 70% of recipients and prevents severe rotavirus gastroenteritis and rotavirus hospitalisation for 85 to 100% of recipients for up to 3 ...
TY - JOUR. T1 - Development of specific nucleic acid probes for the differentiation of porcine rotavirus serotypes. AU - Johnson, Michael E.. AU - Paul, Prem S.. AU - Gorziglia, Mario. AU - Rosenbusch, Ricardo. PY - 1990/9. Y1 - 1990/9. N2 - A dot blot hybridization assay is described for the detection and differentiation of porcine rotavirus serotypes. Recombinant complementary DNA (cDNA) representing gene 9 (the gene encoding the neutralization antigens in VP7 glycoprotein) from OSU (porcine rotavirus serotype 1) and Gottfried (porcine rotavirus serotype 2) strains were used to determine the optimal hybridization conditions which allow specific detection of group A porcine rotaviruses. Probes were prepared by excision of the inserts from the recombinant plasmids and radiolabeling of cDNA with 32P by the random primer extension method. Probes were hybridized at various stringencies with viral RNA from different rotavirus serotypes bound to nylon membranes. Hybridization at low stringency (26% ...
As with many other viruses, the initial cell attachment of rotaviruses, which are the major causative agent of infantile gastroenteritis, is mediated by interactions with specific cellular glycans. The distally located VP8* domain of the rotavirus spike protein VP4 (ref. 5) mediates such interactions. The existing paradigm is that sialidase-sensitive animal rotavirus strains bind to glycans with terminal sialic acid (Sia), whereas sialidase-insensitive human rotavirus strains bind to glycans with internal Sia such as GM1 (ref. 3). Although the involvement of Sia in the animal strains is firmly supported by crystallographic studies, it is not yet known how VP8* of human rotaviruses interacts with Sia and whether their cell attachment necessarily involves sialoglycans. Here we show that VP8* of a human rotavirus strain specifically recognizes A-type histo-blood group antigen (HBGA) using a glycan array screen comprised of 511 glycans, and that virus infectivity in HT-29 cells is abrogated by ...
Rotavirus can cause a gastrointestinal infection and is common in young children. There are two vaccines available; both have to be administered via the mouth. The Dutch Health Council will advise the Ministry of Health, Welfare and Sport on how childhood vaccination against rotavirus will be made available. The Minister makes a decision on the basis of this advice. ,br, To support the Health Council, the RIVM has put together background information on rotavirus disease. The information includes the number of people in the Netherlands that become ill from rotavirus every year, the effectiveness and safety of rotavirus vaccines, and how the public thinks about rotavirus vaccination. ,br, A gastrointestinal infection caused by rotavirus is common during the winter months, particularly in children between six months and two years old. The disease is characterized by fever, vomiting and diarrhoea. Usually, rotavirus disease resolves by itself without problems, but can be severe resulting in ...
We have determined the nucleotide sequence of genes 6 and 10 of porcine rotavirus YM. When the amino acid sequences of VP6 and NS28, the protein products of genes 6 and 10 respectively, were compared with other published sequences it was evident that the proteins of human rotavirus Wa have the highest degree of identity with rotavirus YM. This is in contrast with the observation that when other proteins of these two strains have been compared they have been found to be among the most distantly related pairs of rotavirus strains. This observation is in accordance with the proposed receptor-ligand interaction between NS28 and VP6 during virus morphogenesis, and suggests a specificity in the interaction between these two proteins. In addition, when rotavirus YM VP6, which belongs to subgroup I, was compared with the VP6 proteins of rotavirus strains having different subgroup specificities, it was found to be more closely related to subgroup II rather than subgroup I proteins. This finding allowed us to
Rotavirus, the most common diarrheal pathogen in children worldwide, causes approximately one third of diarrhea-associated hospitalizations and 800,000 deaths per year. Because natural infection reduces the incidence and severity of subsequent episodes, rotavirus diarrhea might be controlled through vaccination. Serotype-specific immunity may play a role in protection from disease. Tetravalent rhesus-human reassortant rotavirus vaccine (RRV-TV) (which contains a rhesus rotavirus with serotype G3 specificity and reassortant rhesus-human rotaviruses with G1, G2, and G4 specificity) provides coverage against the four common serotypes of human rotavirus. In clinical trials in industrialized countries, RRV-TV conferred 49% to 68% protection against any rotavirus diarrhea and 61% to 100% protection against severe disease. This vaccine was licensed by the U.S. Food and Drug Administration on August 31, 1998, and should be cost-effective in reducing diarrheal diseases in industrialized countries. The vaccine&
Johannesburg - Global health dignitaries opened the 9th International Rotavirus Symposium in Johannesburg, South Africa, today. The worlds leading experts on rotavirus will focus on the global burden and the opportunity to significantly reduce child deaths through vaccination against rotavirus in developing countries of Africa and Asia. Over 300 scientists, policymakers, and public health professionals are attending the symposium, convened by four international nonprofit organizations and agencies.. Rotavirus, the leading cause of severe diarrhea, claims the lives of more than 500,000 children under five years of age every year and causes the hospitalization of millions more. Almost half of these deaths occur in sub-Saharan Africa. Although six of the seven countries with the highest infant mortality rates from rotavirus are in Africa, only two percent of the continent has access to rotavirus vaccines. South Africa is the first and only African nation to have introduced rotavirus vaccine into ...
Seasonality of rotavirus infection. We examined the seasonal patterns of disease by plotting the monthly detection of rotavirus in the studies that provided detailed data on rotavirus hospitalization by month (Figure 2). The 10 studies that were identified spanned latitudes from 10° north to 35° south. In most countries, rotavirus was detected throughout the year. The only locations where rotavirus was not detected for 2 consecutive months were Juiz de Fora and Porto Alegre in Brazil. We examined the hypothesis that the seasonality of rotaviruses was distinct in countries located in temperate versus tropical climatic zones. The five studies from cities in the tropics (between 23.5° north and south of the equator) all had winter peaks not unlike the five studies from cities in the temperate zone. As expected, the winter peaks in the northern hemisphere occurred roughly between November and February, while the peaks in the southern hemisphere occurred between May and August.. DISCUSSION.

Rotavirus is a contagious disease caused by any one of three strains of rotavirus. Children who get infected may have severe diarrhea, often with vomiting, fever, and stomach pain. They can become severely dehydrated (loss of body fluids) and need to be hospitalized and can even die.. Infants and young children are most likely to get rotavirus; however, older children and adults can also get the disease. Among U.S. children, those at highest risk of getting the disease include those in child care centers or other settings with many young children. The most severe rotavirus disease occurs in unvaccinated children between 3-35 months old. Older adults and adults with certain risk factors are also at higher risk of getting rotavirus disease.. Rotavirus is easily spread. The virus is in the feces of infected people, and it can be spread by hands, diapers, toys, changing tables, or doorknobs that have a small amount of feces on them. Rotavirus can live on objects for several days unless it is killed ...
Knowledge of rotavirus epidemiology is necessary to make informed decisions about vaccine introduction and to evaluate vaccine impact. During April 2010-March 2012, rotavirus surveillance was conducted among 9,745 children <5 years of age in 14 hospitals/health centers in Niger, where rotavirus vaccine has not been introduced. Study participants had acute watery diarrhea and moderate to severe dehydration, and 20% of the children were enrolled in a nutrition program. Of the 9,745 children, 30.6% were rotavirus positive. Genotyping of a subset of positive samples showed a variety of genotypes during the first year, although G2P[4] predominated. G12 genotypes, including G12P[8], which has emerged as a predominant strain in western Africa, represented >80% of isolates during the second year. Hospitalization and death rates and severe dehydration among rotavirus case-patients did not differ during the 2 years. The emergence of G12P[8] warrants close attention to the characteristics of
tab] [tab_item title="About Rotovirus"] Rotavirus is a contagious virus that can cause gastroenteritis (inflammation of the stomach and intestines). Symptoms include severe watery diarrhea, often with vomiting, fever, and abdominal pain. Infants and young children are most likely to get rotavirus disease. They can become severely dehydrated and need to be hospitalized and can even die. Rotavirus was the leading cause of severe diarrhea among infants and young children in the United States before rotavirus vaccine was introduced in 2006. Prior to the vaccine, almost all U.S. children were infected with rotavirus before their 5th birthday. Globally, rotavirus is still the leading cause of severe diarrhea in infants and young children. In 2008, rotavirus caused an estimated 453,000 deaths worldwide in children younger than 5 years of age.. [/tab_item] [tab_item title="Information for Patients ...
Each year, rotavirus kills more than 200,000 children and hospitalizes millions more. Rotavirus is the most common cause of diarrheal hospitalizations and deaths among children worldwide. Development of a rotavirus vaccine has been a global health priority for many years, and with two vaccines currently on the market and several more under development, the promise of prevention is now becoming reality in several parts of the world.. Sabin is working on numerous fronts to address the burden of rotavirus and facilitate the introduction of a rotavirus vaccine across the globe. In 2011, Sabin, in partnership with the Johns Hopkins Bloomberg School of Public Health, launched the ROTA Council, a rotavirus advocacy initiative, to call attention to this disease and its impact. The ROTA Council, which is comprised of a team of technical experts from around the world, works to provide the scientific and technical evidence that policymakers need to accelerate the introduction of rotavirus vaccines.

Sera from Ecuadorian children of a population-based study and sera from children of a hospital-based study in Germany (excluding diarrhea patients) demonstrated high titers of VP7-specific but only low titers of VP4-specific antibodies. In contrast, paired sera from German children hospitalized with a symptomatic primary rotavirus gastroenteritis demonstrated a titer increase to VP4 more frequently than to VP7 protein by neutralization test and immunoblotting. For these rotavirus patients, we provided, previously, direct evidence ...
The American Academy of Pediatrics (AAP) now recommends a rotavirus vaccine be included in the lineup of routine immunizations given to all infants.. The RotaTeq vaccine has been found to prevent approximately 75% of cases of rotavirus infection and 98% of severe cases. Another vaccine, Rotarix, also is available and is effective in preventing rotavirus infection. Your doctor will have the most current information about these vaccines.. A previous rotavirus vaccine was taken off the market in 1999 because it was linked to an increased risk for intussusception, a type of bowel obstruction, in young infants. Neither RotaTeq nor Rotarix have been found to have this increased risk.. Washing hands well and often is the best way to limit the spread of rotavirus infection. Kids who are infected should stay home from childcare groups until their diarrhea has ended. In hospitals, rotavirus outbreaks are controlled by isolating infected patients and following strict hand-washing procedures.. ...
Infectivity of rotavirus is dramatically enhanced by proteolytic cleavage of its outer layer VP4 spike protein into two function domains, VP8* and VP5*. The carbohydrate-recognising domain VP8* is proposed to bind sialic acid-containing host cell-surface glycans, followed by a series of subsequent virus-cell interactions. Live attenuated human and bovine rotavirus vaccine candidates to prevent gastroenteritis have been derived from bovine rotavirus strain NCDV. The NCDV VP8*64-224 was over-expressed, purified to homogeneity and crystallized in the presence of a N-acetylneuraminic acid derivative. X-ray diffraction data were collected to a resolution of 2.0 Šand the crystallographic structure of NCDV VP8*64-224 determined by molecular replacement ...

Unless babies are vaccinated, almost all of them get rotavirus, the doctor told me. Having the vaccine available for free in Gaza can save babies and parents from so much suffering..". - Majdoolin, first-time mother, Gaza City. The rotavirus vaccine, which RVF worked with the Palestinian Ministry of Health (MOH) to introduce in 2016, is already having a huge impact on young children in the West Bank and Gaza. In Gaza, there has already been a 28% reduction in rates of children aged three years and under hospitalized for diarrhea. In the West Bank, there are over a third fewer cases of severe diarrhea in children under five.. Rotavirus disease, which causes severe diarrhea, is a killer of infants and young children throughout the world. Vaccination is the most effective way to prevent rotavirus infection. All Palestinian babies now receive this life-saving vaccine. To date, nearly 400,000 infants have been fully immunized with coverage rates over 95%.. RVF expects rates of severe diarrhea in ...

Whole-genome, sequence-independent amplification and 454 pyrosequencing of a rotavirus SA11 cell culture sample with an unknown passage history yielded consensus sequences of twelve complete genome segments. Two distinct sequences for genome segment 8 (encoding NSP2) were present, indicating a mixed infection with two rotavirus SA11 strains. The genotypes of the viruses were G3-P[2]-I2-R2-C5-M5-A5-Nx-T5-E2-H5, where x was either 5 or 2. The strains were named RVA/ Simian-tc/ZAF/SA11-N5/1958/G3P[2] and RVA/Simiantc/ ZAF/SA11-N2/1958/G3P[2]. The genotype (N2) and sequence of genome segment 8 of RVA/Simian-tc/ZAF/ SA11-N2/1958/G3P[2] were identical to that of the bovine rotavirus O agent. Five novel amino acids were detected in minor population variants of three genome segments. Genome segment 1 (VP1) has a high nucleotide substitution rate, but the substitutions are synonymous. Distance matrices and Bayesian molecular clock phylogenetics showed that SA11-N2 is a reassortant containing genome ...
by revere, cross-posted at Effect Measure. Earaches, respiratory infections and diarrhea are the bane of existence for young parents. All are potentially the result of contagious agents. The most common agent for diarrhea in infants and children is rotavirus, a double-stranded DNA virus, that CDC estimates causes 400,000 doctor visits, 200,000 emergency room visits and 55.000 to 70,000 hospitalizations each year in the under 5 year old age group. Infection produces significant immunity, and while there are seven different serotypes (A through G), 90% of infections are serotype A. In addition to diarrhea, rotavirus infections cause nausea, vomiting and fever, often with dehydration that can be fatal to an infant. By the time a child turns five, he or she is likely to have had a rotavirus infection. So this virus causes a lot of sickness and even more dollars. A recent estimate is that each hospitalization costs about $3600.. If rotavirus infection could be prevented by a vaccine it would have a ...
The advantages of convenience and room temperature stability associated with our quick dissolving thin film delivery system can be broadly used. The thin film system is applicable to all oral vaccines and oral protein based therapeutic drugs, as well as biopharmaceuticals that can be converted to the oral route. The impact on vaccines could be transformational for infectious diseases such as shigellosis and rotaviral gastroenteritis which combined cause over 1 million deaths in children every year in the developing world. Considering rotavirus alone, the demand for any vaccine will likely be high since all children by the age of five will have been infected by rotavirus and many children in third world countries will die. Currently, it is recommended that all new born infants in the U.S. be given rotavirus vaccine and it is highly likely that most of the world will follow this recommendation. It is estimated that the required annual worldwide rotavirus vaccine doses will be greater than 400 ...
Human rotavirus A (RVA) is the main etiological agent of watery diarrhea among children under 5 years of age worldwide. The aims of this study were to investigate the prevalence and diversity of RVA genotypes circulating in Turkey during a 2-year sentinel surveillance study. A total of 1639 rotavirus antigen-positive stool samples were obtained from children younger than 5 years of age hospitalized with acute gastroenteritis. Rotavirus G and P genotypes were determined by reverse transcription polymerase chain reaction (RT-PCR) with consensus primers for the VP7 and VP4 genes, followed by semi-nested type-specific multiplex PCR. Rotavirus RNA was detected in 1396 (85.3%) of the samples tested. The highest detection rate (38.2%) was obtained among children in the 0-12 months age group, followed by children in the 13-24 months age group (36.2%). The most prevalent genotype was G1P[8] (24.6%) followed by G3P[8] (19.6%), G9P[8] (12.2%), G2P[4] (9.5%), G2P[8] (6.5%), and G4P[8] (4.8%). The ...

A resurgence in rotavirus gastro cases among infants has prompted warnings from health authorities about the importance of hand hygiene and vaccination.. South Australian communicable disease experts have sounded the alarm after the number of rotavirus cases among infants more than doubled from 299 in 2016 to 658 so far in 2017.. Infants accounted for 60% of all rotavirus notifications, with total numbers across all age groups increasing almost threefold from 447 to 1255 in the last year.. SA Healths Chief Medical Officer Professor Paddy Phillips says the increase in rotavirus among infants is worrying but preventable with good hand hygiene and vaccination.. "Following good hand hygiene, cleaning bathroom taps and toilets with diluted bleach, disposing of infants nappies immediately, and safely washing childrens toys helps to significantly prevent the spread of the disease," he said in a statement.. A rise in rotavirus cases is being seen in other states, according to Dr Louise Flood, Acting ...
Comment: This is interesting news, since the Bharat Biotech vaccine for Rotavirus (116 E) made in India has already undergone the necessary testing & is likely to be launched in the next couple of months (possibly Jan 2015). Among all the newer vaccines, rotavirus is the only one where we have large amount of Indian data available regarding the disease from India through the IRSN - Indian Rotavirus Surveillance Network. This is probably one of the reasons why we are getting India specific vaccines for this disease. It is important to start vaccinating children early against this disease so as to prevent significant disease burden, since almost EVERY child will suffer from Rotavirus diarrhea if they are not vaccinated, probably by the age of 2 years. ...
In the United States, rotavirus infection outbreaks are common during the winter and spring months. Outbreaks are particularly problematic in childcare centers and childrens hospitals because the infection spreads so easily.. Rotavirus symptoms can last from 3-8 days and include fever, nausea, vomiting, abdominal cramps, and frequent, watery diarrhea. A cough and runny nose may also occur. Some rotavirus infections cause few or no symptoms at all, especially in adults.. The diarrhea from a rotavirus infection can be so severe that it quickly leads to dehydration, especially in infants and young children. If dehydration is severe, intravenous (IV) fluids given in the hospital can bring the bodys fluid and salt levels back to normal.. ...

Spike-forming protein that mediates virion attachment to the host epithelial cell receptors and plays a major role in cell penetration, determination of host range restriction and virulence. Rotavirus entry into the host cell probably involves multiple sequential contacts between the outer capsid proteins VP4 and VP7, and the cell receptors. According to the considered strain, VP4 seems to essentially target sialic acid and/or the integrin heterodimer ITGA2/ITGB1 (By similarity).
Bovine rotavirus (BRV) is a non-enveloped dsRNA virus that cause neonatal calf diarrhea. Lipid rafts are cholesterol-enrich membrane mircodomains that play a vital role in many cellular processes. In this study, the effect of cellular cholesterol depletion on infection of MA-104 cells with bovine rotavirus was investigated. We demonstrated that cholesterol depletion of the plasma membrane by MβCD had no effect on BRV binding to cells but significantly impaired BRV entry in a dose-dependent manner and the effect was partially reversed by addition of exogenous cholesterol, suggesting the reduction of BRV infection by MβCD was specifically due to cholesterol depletion. Cholesterol depletion after virus entry did not reduce BRV replication, whereas affected virus assembly. Taken together, our results demonstrate that cell membrane cholesterol is essential to BRV infectivity.

My moms entry in my baby book describing the incident.. After learning about this, there was first the mindboggling realization that the disease I had been researching and writing about every day had touched my family and me personally, and I had had no idea. Not only had rotavirus sent me to the hospital, it had also forced my mom to miss two days of work and cost my family a lot of stress and expenses. I then had the revelation that the little girl described above could be almost any little girl or boy, anywhere in the world, whether decades ago or today. Rotavirus is called the "democratic" virus-without protection from vaccines, rotavirus infects nearly all children everywhere, rich or poor, by the age of five and is the most common cause of severe diarrhea in the world. It does not matter if you are in the United States or Nepal, if you live in a mansion or a grass hut, or if you drink water from a river or a well: rotavirus is everywhere..

What you can do in the meantime. Drink plenty of fluids. Stick with bland foods to reduce stress on your digestive system. If your child is sick, follow the same approach - offer plenty of fluids and bland food. If youre breast-feeding or using formula, continue to feed your child as usual. Ask your childs doctor if giving your child an oral rehydration fluid is appropriate.. Rotavirus is often diagnosed based on symptoms and a physical exam. A stool sample may be analyzed in a lab to confirm the diagnosis.. Theres no specific treatment for a rotavirus infection. Antibiotics wont help a rotavirus infection. Usually, the infection resolves within three to eight days. Preventing dehydration is the biggest concern.. To prevent dehydration while the virus runs it course, drink plenty of fluids. If your child has severe diarrhea, ask your doctor about offering an oral rehydration fluid such as Pedialyte - especially if the diarrhea lasts longer than a few days. For children, a rehydration fluid ...
Rotavirus is the main cause of viral gastroenteritis in young children. potentially be used as immunoprophylactic and/or immunotherapeutic products for the prevention and/or treatment of infection of a broad range of clinically relevant rotavirus strains. Introduction Rotavirus is a non-enveloped, icosahedral virus of the family containing a genome of 11 segments of double stranded RNA (dsRNA). Recently, it has been estimated that each year, rotavirus causes more than a 100 million episodes of gastroenteritis which results in 25 million clinic visits, 2 million hospitalizations, and more than 611,000 deaths in children below BTZ043 5 years of age [1]. By 5 years of age, nearly every child worldwide will have had at least one Rabbit Polyclonal to Cytochrome P450 39A1. episode of rotavirus gastroenteritis [2]. Children in developing countries account for 82% of rotavirus deaths. Therefore, rotavirus remains the most important cause of severe and life threatening viral gastroenteritis and ...
For centuries, acute diarrhea has been a major worldwide cause of death in young children, and until 1973, no infectious agents could be identified in about 80% of patients admitted to hospital with severe dehydrating diarrhea. In 1973 Ruth Bishop, Geoffrey Davidson, Ian Holmes, and Brian Ruck identified abundant particles of a new virus (rotavirus) in the cytoplasm of mature epithelial cells lining duodenal villi and in feces, from such children admitted to the Royal Childrens Hospital, Melbourne. Rotaviruses have now been shown to cause 40-50% of severe acute diarrhea in young children worldwide in both developing and developed countries, and , 600 000 young children die annually from rotavirus disease, predominantly in South-East Asia and sub-Saharan Africa. Longitudinal surveillance studies following primary infection in young children have shown that rotavirus reinfections are common. However the immune response that develops after primary infection is protective against severe symptoms ...

Rotavirus infection induces an increase in [Ca2+]cyto, which in turn may affect the distribution of the cytoskeleton proteins in the infected cell. Changes in microfilaments, including the formation of stress fibers, were observed starting at 0.5 h.p.i. using fluorescent phalloidin. Western blot analysis indicated that RhoA is activated between 0.5 and 1 h.p.i. Neither the phosphorylation of RhoA nor the formation of stress fibers were observed in cells infected with virions pre-treated with an anti-VP5* non-neutralizing mAb, suggesting that RhoA activation is stimulated by the interaction of the virus with integrins forming the cell receptor complex. In addition, the structure of the tubulin cytoskeleton was also studied. Alterations of the microtubules were evident starting at 3 h.p.i. and by 7 h.p.i. when microtubules were markedly displaced toward the periphery of the cell cytoplasm. Loading of rotavirus-infected cells with either a Ca2+ chelator (BAPTA) or transfection with siRNAs to silence NSP4,
Rotavirus triple-layered particles. Rotavirus virions are triple-layered particles with icosahedral symmetry. The spike protein and the glycoprotein VP7 compose the external layer. Meanwhile, a unique component, VP6, is part of the middle layer. The VP2 icosahedral internal layer or virus core e ...
LETTERS TO THE EDITOR. Outbreak of intra-hospital acquired rotavirus in a pediatric hospital in Mexico. To the Editor: Rotavirus constitutes the principal causal agent of intra-hospital diarrhea in children, with a described incidence of intra-hospital gastroenteritis of 2 to 7% of hospitalized children primarily between 6 and 23 months old.1 The transmission is from person to person and the virus survives on the hands of health workers during four hours; in inanimate objects it could survive for several days. For this reason, health workers are considered to be the probable cause of transmission in the majority of the cases.2-3 People infected by rotavirus generally present acute vomiting followed by profuse, watery diarrhea without blood and with or without fever. The first episode is normally very serious, thus the clinical signs are very severe in children as well as in immunocompromised patients and elderly people.4-5. The objective of this letter is to briefly comment on the presentation ...
Yes, rotavirus does go through a lysogenic cycle during replication. Rotavirus makes most copies of itself in its host's gut. Rotavirus is notorious for causing severe diarrhea in its host, and is one of the leading causes of severe dehydration in children.Source:Viral ContaminationRotavirus
Introduction Without immunisation, almost all children in the world are infected by rotavirus before five years of age. It is recognised as the most common cause of diarrhoea (loose stools) and dehydration in infants and young children in all countries. Adults can also become infected. Rotavirus was first identified in 1973 and was named rotavirus because of the wheel-like appearance of the virus.
KinderMender has been busy treating an influx of young patients presenting with vomiting, diarrhea, and watery stools.. This isnt the work of influenza, however. The flu is an "all over" sort of nastiness, affecting a wide spectrum of systems. It causes congestion, sore throat, coughing, and more.. In lieu of those telltale respiratory issues, one suspect emerges: Rotavirus.. Globally, rotavirus is the most common cause for diarrheal illness in infants and children. In the United States, where vaccinations are common, it is easily singled out by its distinct seasonality (typically winter and early spring) and the way it spreads. Daycares and schools, unfortunately, are common breeding grounds.. Rotavirus enters the environment through feces. The illness is often spread when children do not wash their hands properly after using the restroom, or when parents and guardians do not wash their hands after assisting their child, or when changing a diaper. The virus then proceeds to contaminate toys, ...
