Despite high vaccination coverage in most European countries, large community outbreaks of measles do occur, normally clustered around schools and resulting from suboptimal vaccination coverage. To determine whether or when it is worth implementing outbreak-response vaccination campaigns in schools, we used stochastic outbreak models to reproduce a public school outbreak in Germany, where no vaccination campaign was implemented. We assumed 2 scenarios covering the baseline vaccination ratio range (91.3%-94.3%) estimated for that school and computed outbreaks assuming various vaccination delays. In one scenario, reacting (i.e., implementing outbreak-response vaccination campaigns) within 12-24 days avoided large outbreaks and reacting within 50 days reduced outbreak size. In the other scenario, reacting within 6-14 days avoided large outbreaks and reacting within 40 days reduced the outbreak size. These are realistic time frames for implementing school outbreak response vaccination campaigns. ...
BACKGROUND: Within outbreaks of Escherichia coli O157 (E. coli O157), at least 10-15% of cases are thought to have been acquired by secondary transmission. However, there has been little systematic quantification or characterisation of secondary outbreak cases worldwide. The aim of this study was to characterise secondary outbreak cases, estimate the overall proportion of outbreak cases that were the result of secondary transmission and to analyse the relationships between primary and secondary outbreak cases by mode of transmission, country and median age. METHODS: Published data was obtained from 90 confirmed Escherichia coli O157 outbreaks in Great Britain, Ireland, Scandinavia, Canada, the United States and Japan, and the outbreaks were described in terms of modes of primary and secondary transmission, country, case numbers and median case age. Outbreaks were tested for statistically significant differences in the number of ill, confirmed, primary and secondary cases (analysis of variance ...
Zika is a significant global public health issue. We demonstrate that, based on an average infectious period of 5.5 days17,18, Zika virus transmission by vector mosquitoes could have occurred in Cairns, Townsville and Rockhampton during the warmer months in 2015 and 2016, with Brisbane unsuitable for transmission. However, this changes when we take a lower epidemic potential threshold, based on a longer infectious period. Except for Brisbane where the vector is not yet established, these results are consistent with the epidemic potential of dengue virus in Cairns and Townsville.. While estimates are preliminary, these analyses point to the importance of further investigations of the infectious period as well as the infection and transmission rates of ZIKV and Australian mosquitoes (Ae. aegypti and Ae. albopictus) to allow more accurate estimates of the epidemic potential for ZIKV in Australia.. The Rio de Janeiro 2016 Olympics (5-21 August 2016) and the Paralympic Games (7-18 September 2016) ...
The outbreak investigation was coordinated by the Danish Veterinary and Food Administration (DVFA) in cooperation with Statens Serum Institut (SSI) and The National Food Institute at the Technical University of Denmark (DTU-FOOD). The Danish Regional Food Control Offices, under the DVFA, conducted separate local outbreak investigations. An outbreak was considered a part of the meta-outbreak if the outbreak occurred in Denmark in March-April 2016 after consumption of green coral lettuce from France.. Local outbreak investigations were conducted via contact to outbreak venues and kitchens responsible for the catering to establish the circumstances of the outbreaks. Further investigations were then done to establish attack rate and food exposure details. Stool sample kits were distributed directly to patients by the local investigators where possible. Patients were encouraged to send in two separate stool samples to the SSI. Stool samples analysis was performed at the SSI and food sample analysis ...
Here, we analyse human infectious disease outbreaks across the world, spanning multiple decades. Our results provide new descriptions of the global disease-scape and our new dataset, now available for others to use, will help advance the field of disease biogeography.. While outbreaks represent an increase in the number of disease cases beyond expectations for a given population, emerging human infectious diseases are further characterized by novelty: for example, diseases that have undergone recent evolutionary change, entered the human population for the first time, or have been newly discovered [5,9]. The number of outbreaks, like the number of emerging infectious diseases, appears to be increasing with time in the human population both in total number and richness of causal diseases. Although our finding implies that outbreaks are increasing in impact globally, outbreak cases per capita appear to be declining over time. Our data suggest that, despite an increase in overall outbreaks, global ...

Background Pertussis control remains a challenge due to recently observed effects of waning immunity to acellular vaccine and suboptimal vaccine coverage. Multiple outbreaks have been reported in different ages worldwide. For certain outbreaks, public health authorities can launch an outbreak response immunization (ORI) campaign to control pertussis spread. We investigated effects of an outbreak response immunization targeting young adolescents in averting pertussis cases. Methods We developed an agent-based model for pertussis transmission representing disease mechanism, waning immunity, vaccination schedule and pathogen transmission in a spatially-explicit 500,000-person contact network representing a typical Canadian Public Health district. Parameters were derived from literature and calibration. We used published cumulative incidence and dose-specific vaccine coverage to calibrate the models epidemiological curves. We endogenized outbreak response by defining thresholds to trigger simulated
Foodborne pathogens are responsible for an increasing burden of disease worldwide. Knowledge on the contribution of different food sources and water for disease is essential to prioritize food safety interventions and implement appropriate control measures. Source attribution using outbreak data utilizes readily available data from outbreak surveillance to estimate the contribution of different sources to human disease. We developed a probabilistic model based on outbreak data that attributes human foodborne disease by various bacterial pathogens to sources in Latin America and the Caribbean (LA&C). Foods implicated in outbreaks were classified by their ingredients as simple foods (i.e. belonging to one single food category), or complex foods (i.e. belonging to multiple food categories). For each agent, the data from simple-food outbreaks were summarized, and the proportion of outbreaks caused by each category was used to define the probability that an outbreak was caused by a source. For the ...
The Hawaii Department of Health has confirmed two cases of severe respiratory illness associated with e-cigarette use (also known as vaping). The first illness occurred in a Hawaii island resident under the age of 18 years. The second illness occurred in a young adult resident from Kauai. Both cases appear to be linked to a national outbreak.. As of October 15, more than 1,400 cases have been reported in 49 states (all except Alaska), including 33 deaths reported in 24 states. No single type of vaping device or product has been identified as the cause of the lung injuries and illnesses, but investigations are ongoing.. The Disease Outbreak Control Division is investigating all reported cases and coordinating with state and federal partners to try to identify the cause.. For current recommendations on e-cigarettes and vaping for the public, go here.. ...
Michael E. St. Louis, M.D. Enteric Disease Branch, Division of Bacterial Diseases, Center for Infectious Diseases INTRODUCTION Since 1971 CDC has tabulated data on waterborne disease outbreaks separately from those for foodborne disease outbreaks and compiled these data in annual reports. The Water-Related Diseases Activity has the following goals: 1) to determine trends in the incidence of water-related diseases in the United States, 2) to characterize the epidemiology of water-related diseases, 3) to disseminate information on prevention and control of water-related diseases to appropriate public health personnel, 4) to train federal, state, and local health department personnel in epidemiologic techniques used to investigate water-related disease outbreaks, and 5) to collaborate with local, state, and other federal and international agencies in initiatives concerning prevention of water-related diseases. In addition to waterborne disease outbreaks associated with water intended for drinking, ...
The study, published Feb. 21 in the CDC journal Emerging Infectious Diseases, reviewed dairy product outbreaks from 1993 to 2006 in all 50 states. The authors compared the amount of milk produced in the United States during the study period (about 2.7 trillion pounds) to the amount that CDC estimates was likely consumed raw (1 percent or 27 billion pounds) to determine the 150 times higher rate for outbreaks caused by raw milk products. Raw milk products include cheese and yogurt.. The study included 121 dairyrelated disease outbreaks, which caused 4,413 illnesses, 239 hospitalizations and three deaths. In 60 percent of the outbreaks (73 outbreaks) state health officials determined raw milk products were the cause. Nearly all of the hospitalizations (200 of 239) were in those sickened in the raw milk outbreaks. These dairy-related outbreaks occurred in 30 states, and 75 percent (55 outbreaks) of the raw milk outbreaks occurred in the 21 states where it was legal to sell raw milk products at ...

E. coli bacteria co-exist with humans and animals in harmless symbiosis, however, every year they also cause infections and deaths. Disease outbreaks caused by E. coli most commonly occur after contact with contaminated food or water. A recent example of a disease outbreak caused by E. coli comes from Germany, where, in 2011, several thousand people were contaminated and 50 deaths were recorded.. Disease outbreaks caused by bacteria can never completely be avoided, however, their extent can be minimised by quickly detecting them and locating the source. As part of his PhD project, Rolf Sommer Kaas from the National Food Institute has developed a freely accessible internet-based tool, CSI Phylogeny. The tool can analyse bacterias genetic material, e.g. that of E. coli, and determine the bacterial evolutionary tree, i.e. how the bacteria are related. This information can be used as a starting point for quickly finding the outbreak source.. ...

Outbreaks of multidrug-resistant bacteria present a frequent threat to vulnerable patient populations in hospitals around the world. Intensive care unit (ICU) patients are particularly susceptible to nosocomial infections due to indwelling devices such as intravascular catheters, drains, and intratracheal tubes for mechanical ventilation. The increased vulnerability of infected ICU patients demonstrates the importance of effective outbreak management protocols to be in place. Understanding the transmission of pathogens via genotyping methods is an important tool for outbreak management. Recently, whole-genome sequencing (WGS) of pathogens has become more accessible and affordable as a tool for genotyping. Analysis of the entire pathogen genome via WGS could provide unprecedented resolution in discriminating even highly related lineages of bacteria and revolutionize outbreak analysis in hospitals. Nevertheless, clinicians have long been hesitant to implement WGS in outbreak analyses due to the ...

An outbreak of Salmonella Typhimurium linked to ground beef that started in early December of 2012 is now thought to have ended in mid-February after sickening a total of 22 people, announced the U.S. Centers for Disease Control and Prevention Friday.. The 22 illnesses linked to the outbreak occurred in 6 states: Arizona (1 case), Illinois (2 cases), Iowa (1 case), Michigan (9 cases), Pennsylvania (1 case), and Wisconsin (8 cases).. Among the 14 outbreak victims for whom information was available, half were hospitalized, according to CDCs final outbreak report. No deaths were connected to the outbreak.. The type of Salmonella Typhimurium that caused this outbreak is uncommon, according to CDC.. This PFGE (pulsed-field gel electrophoresis) pattern has rarely been seen before in PulseNet and in the past typically caused 0-1 cases per month, said the agency in its outbreak report.. Ground beef products made by two companies - Jouni Meats and Gab Halal Foods - are considered the likely source of ...
A new approach to information gathering could allow scientists to quickly identify the most effective way to manage a disease outbreak, an advance that could save lives. Developed by an international team of researchers led by Penn State scientists using insights from the 2014 Ebola outbreak, the method pinpoints critical pieces of missing information required to improve management decisions during an outbreak.
Abstract: Identifying important nodes for disease spreading is a central topic in network epidemiology. We investigate how well the position of a node, characterized by standard network measures, can predict its epidemiological importance in any graph of a given number of nodes. This is in contrast to other studies that deal with the easier prediction problem of ranking nodes by their epidemic importance in given graphs. As a benchmark for epidemic importance, we calculate the exact expected outbreak size given a node as the source. We study exhaustively all graphs of a given size, so do not restrict ourselves to certain generative models for graphs, nor to graph data sets. Due to the large number of possible nonisomorphic graphs of a fixed size, we are limited to 10-node graphs. We find that combinations of two or more centralities are predictive ($R^2$ scores of 0.91 or higher) even for the most difficult parameter values of the epidemic simulation. Typically, these successful combinations ...
Our analyses demonstrate the epidemiological importance of variation in group size in social species. As the variance of the group size distribution increases, the model demonstrates that the epidemic threshold decreases and that both the mean and variance of small outbreak sizes should increase. Above the epidemic threshold, that is, for diseases capable of causing large epidemics, the effect of group size variability depends on the transmissibility of the disease. For mildly contagious diseases, more variable group sizes promote larger epidemics, whereas for more highly contagious diseases, the effect reverses and group size variability inhibits epidemics.. These findings have important implications for disease-control strategies, including vaccination, quarantine and culling, which often target social groups that are likely to decrease the epidemic threshold. Prior studies have highlighted the importance of targeting groups with high numbers of interacting neighbours or who occupy a central ...
We are currently experiencing an unprecedented challenge, managing and containing an outbreak of a new coronavirus disease known as COVID-19. While China-where the outbreak started-seems to have been able to contain the growth of the epidemic, different outbreaks are nowadays present in multiple countries. Nonetheless, authorities have taken action and implemented containment measures, even if not everything is known. To facilitate this task, we have studied the effect of different containment strategies that can be put into effect. Our work referred initially to the situation in Spain as of February 28, 2020, where a few dozens of cases had been detected, but has been updated to match the current situation as of 13 April. We implemented an SEIR metapopulation model that allows tracing explicitly the spatial spread of the disease through data-driven stochastic simulations. Our results are in line with the most recent recommendations from the World Health Organization, namely, that the best strategy is
University of Guelph researchers have received a $375,000 Health Canada grant to develop a database program to help pinpoint causes of disease outbreaks. The first-of-its-kind project will link animal health, food safety and human health data to speed up the identification and evaluation of disease outbreak sources. For example, if Health Canada was trying to determine the cause of a Salmonella outbreak in humans, the database would specify any related outbreaks in farm or pet animals and related contaminated food products. Time is key in these events -- people can become very ill or die during disease outbreaks -- so speedy recognition and evaluation are critical, said Beverly McEwen, one of the project co-ordinators from the Universitys Animal Health Laboratory. The grant was awarded by Federal Health Minister Allan Rock through Health Canadas Health Infostructure Support Program (HISP), which supports the use of new technologies in health. The grant will be used for hardware, software and ...

Several high-profile outbreaks have drawn attention to invasive fungal infections (IFIs) as an increasingly important public health problem. IFI outbreaks are caused by many different fungal pathogens and are associated with numerous settings and sources. In the community, IFI outbreaks often occur among people without predisposing medical conditions and are frequently precipitated by environmental disruption. Health-care-associated IFI outbreaks have been linked to suboptimal hospital environmental conditions, transmission via health-care workers hands, contaminated medical products, and transplantation of infected organs. Outbreak investigations provide important insights into the epidemiology of IFIs, uncover risk factors for infection, and identify opportunities for preventing similar events in the future. Well recognised challenges with IFI outbreak recognition, response, and prevention include the need for improved rapid diagnostic methods, the absence of routine surveillance for most ...
The Ohio Department of Health (ODH) declared a statewide community outbreak in June 2018 after observing an increase in hepatitis A cases. Hepatitis A is a vaccine-preventable liver disease that usually spreads when a person ingests fecal matter - even in microscopic amounts - from contact with objects, food or drinks contaminated by the stool of an infected person. Hepatitis A can also be spread from close personal contact with an infected person, such as through sex. The statewide community outbreak is spread through person-to-person contact.. In May 2019, the Centers for Disease Control and Prevention (CDC) provided an updated case definition resulting in an increase in the number of outbreak cases in Ohio. ODH and local health departments continue to investigate reported hepatitis A cases.. The high-risk populations for hepatitis A in this outbreak include:. ...

The recent surge in reported mumps cases in Hidalgo County coincides with two nationwide trends. The first is the alarming increase of communicable diseases that just a few years ago were considered under control or effectively eradicated. The other, however, is a growing number of U.S. residents who arent getting vaccinated.. The Hidalgo County Health Department has reported some 20 confirmed or suspected cases of mumps, a viral disease that causes swelling and tenderness in several glands in the body. It often attacks the salivary glands and traditionally is characterized by swelling in the jaw and neck area. In rare cases it can affect the brain or pancreas, causing pancreatitis, meningitis or even encephalitis.. Historically the disease was more prevalent among young children, but the current local outbreak is can affect more adults. Thats alarming, as the disease can be more severe as the patients age. Mumps affects the reproductive organs in one in four men and one in 20 women who catch ...
Giardia is not endemic in Norway, and more than 90% of reported cases acquire the infection abroad. In late October 2004, an increase in laboratory confirmed cases of giardiasis was reported in the city of Bergen. An investigation was started to determine the source and extent of the outbreak in order to implement control measures. Cases were identified through the laboratory conducting giardia diagnostics in the area. All laboratory-confirmed cases were mapped based on address of residence, and attack rates and relative risks were calculated for each water supply zone. A case control study was conducted among people living in the central area of Bergen using age- and sex matched controls randomly selected from the population register. The outbreak investigation showed that the outbreak started in late August and peaked in early October. A total of 1300 laboratory-confirmed cases were reported. Data from the Norwegian Prescription Database gave an estimate of 2500 cases treated for giardiasis probably

The deadly Ebola virus is taking a toll on the Democratic Republic of the Congo. Since its reemergence this year, some 1,625 people have died, and on July 17, the World Health Organization declared the outbreak a public health emergency of international concern. It has menaced communities across the countrys north, and individual cases have now reached the city of Goma, near the Congo-Rwanda border, and even spilled into Uganda.. In fragile states like Congo-beset by poverty, instability, and weak governance-not only do disease outbreaks routinely expand into neighboring countries, but they also tend to aggravate other health problems. For example, after the last Ebola outbreak weakened Congos already fragile and overtasked health system, the North Kivu province, where the outbreak is centered, saw an eightfold increase in the incidence of malaria. Simply put, it may be too much to expect a country like Congo to contain an outbreak while also dealing with a host of other problems, including a ...

There are many times when it is safe to begin treatment as opposed to waiting for a second or third round of the outbreak. The outbreak can be stopped before any complications arise. The most common scenario that doctors deal with is to have an outbreak that continues to recur for several weeks or months. Its also a scenario that involves the transmission of a disease.. A very common symptom of an outbreak is a period of increased fatigue and nausea. An outbreak is caused by parasites, which often occur in an individuals intestinal tract. The parasites often enter the body through food and water that are contaminated by the other person.. If your individual is experiencing such symptoms, you can start treatment immediately by applying the appropriate kind of treatment for your symptoms. The symptoms of an outbreak vary greatly depending on the type of illness that the individual has. Most importantly, an outbreak is one of the most infectious situations possible. When you have a severe case of ...
At 37, Dotti Lesak had already been working at the Fairfax County Department of Public Health for 13 years. Having trained as a medical technician, she loved working in the public health laboratory where she was a bench scientist. Dottis favorite part was being a part of the public health team to identify potential outbreaks of tuberculosis and provide laboratory results so patients could be treated with the right drugs. She recently noticed an uptick in the number of samples submitted from young people in Fairfax County, and even more alarming, were the two positive TB cases the laboratory found among this group. She assumed Jim was there to discuss those cases ...
If the weather is still having an effect on the rate constant, hopefully theres a bit of respite ahead for case numbers; what a week. Im starting with the same new plots as last week - Plot A - Stylistic Cases only shows the full detail for the biggest growth areas, otherwise rising cases are represented by a straight orange line linking their first and last values on the plot, and falling cases a similar blue line. I hope this brings some clarity to the split in behaviours - lockdown working in some places, lockdown failing in others (more than last week) with cases gently rising, and a few places having major outbreaks. Plot B shows the average cases/100k for the non-outbreak rising areas and the falling areas.. Its interesting that the resurgence in cases since May 21st in Blackburn with Darwen and Bolton seems to tally with a rising phase in many of the other outbreak areas. Big picture - the very short doubling times seen in Bolton didnt last, and havent been seen for long anywhere ...

BACKGROUND: Prior to the COVID-19 pandemic, physicians experienced unprecedented levels of burnout. The uncertainty of the ongoing COVID-19 pandemic along with increased workload and difficult medical triage decisions may lead to a further decline in physician psychological health. METHODS: We searched Medline, EMBASE, and PsycINFO for primary research from database inception (Medline [1946], EMBASE [1974], PsycINFO [1806]) to November 17, 2020. Titles and abstracts were screened by one of three reviewers and full-text article screening and data abstraction were conducted independently, and in duplicate, by three reviewers. RESULTS: From 6223 unique citations, 480 articles were reviewed in full-text, with 193 studies (of 90,499 physicians) included in the final review. Studies reported on physician psychological symptoms and management during seven infectious disease outbreaks (severe acute respiratory syndrome [SARS], three strains of Influenza A virus [H1N1, H5N1, H7N9], Ebola, Middle East
Epidemics & Infectious Diseases : Unit 2: Hosts Lesson 7 - Detecting an Infectious Disease Outbreak Video about Epidemics & Other Diseases from
Several cases have been linked by investigation and/or viral sequencing to a national outbreak of hepatitis A involving cases in California and Arizona.. More than half the outbreak cases required hospitalization. The vast majority of outbreak cases were reported from two counties-Salt Lake (85) and Utah (26). No deaths have been reported.. The high rate of hospitalization may be a result of cases having underlying illnesses (e.g., alcoholism), or a higher rate of hepatitis comorbidities (e.g., hepatitis B or C).. Hepatitis A is usually spread through having oral contact with items contaminated with hepatitis A, for example, through ingesting food or drinks contaminated by infected feces. Some people do not develop symptoms, even if infected. If symptoms occur, they usually appear anywhere from 2-6 weeks after exposure. Symptoms usually develop over a period of several days, and may include jaundice (the yellowing of the skin or whites of the eyes), abdominal pain, nausea or diarrhea. Hepatitis ...
Outbreaks of deadly animal-to-human viruses such as Ebola could become more likely due to climate change and human encroachment into untouched natural habitats, a leading United Nations expert has warned. Dr. David Nabarro, the U.N. secretary-generals special envoy on Ebola, told The Independent the world should prepare for more major outbreaks of zoonotic diseases - those which can pass from animals to humans - which he said were a local and global threat to humanity… (Cooper, 4/5).. ...

Each year in the United States, ∼260,000 people get sick from contaminated fish. Fish is also the most commonly implicated food category in outbreaks. We reviewed the Centers for Disease Control and Prevention Foodborne Disease Outbreak Surveillance System for outbreaks resulting from consumption of fish during the period 1998-2015. We found 857 outbreaks associated with fish, resulting in 4815 illnesses, 359 hospitalizations, and 4 deaths. The median number of illnesses per outbreak was three (range: 2-425). The annual number of fish-associated outbreaks declined from an average of 62 per year during the period 1998-2006 to 34 per year during the period 2007-2015. Hawaii (221 outbreaks [26%]) and Florida (203 [24%]) reported the most outbreaks. Among 637 outbreaks (74%) with a confirmed etiology, scombrotoxin (349 [55%]) and ciguatoxin (227 [36%]) were by far most common. Most outbreak-associated illnesses were caused by scombrotoxin (1299 [34%]), Salmonella (978 [26%]), and ciguatoxin (894 ...
ABSTRACT. Background: The United States is the third largest consumer of seafood in the world. Consumption of seafood has many health benefits, but there are also associated risks. Seafood has the potential to carry chemical and biological toxins that can result in severe cases of foodborne illness and even death. In fact, fish is one of the top 3 food commodities implicated in foodborne disease outbreaks each year. In this paper, we describe the epidemiological traits of fish-associated outbreaks from 1998-2008, as well as seek to elucidate associations between fish type, method of preparation, setting, and geographic location.. Methods: Fish-associated outbreak data from CDCs Foodborne Disease Outbreak Surveillance System were analyzed in this report and included number of illnesses, hospitalizations and deaths, age groups, gender, reporting state, etiology, fish type, setting, and method of preparation. Univariate and multivariate logistic regression were used to identify risk factors for ...
The frequency and severity of recurrent outbreaks vary greatly between people. Some individuals outbreaks can be quite debilitating, with large, painful lesions persisting for several weeks, while others experience only minor itching or burning for a few days. Some evidence indicates genetics play a role in the frequency of cold sore outbreaks. An area of human chromosome 21 that includes six genes has been linked to frequent oral herpes outbreaks. An immunity to the virus is built over time. Most infected individuals experience fewer outbreaks and outbreak symptoms often become less severe. After several years, some people become perpetually asymptomatic and no longer experience outbreaks, though they may still be contagious to others. Immunocompromised individuals may experience longer, more frequent, and more severe episodes. Antiviral medication has been proven to shorten the frequency and duration of outbreaks.[79] Outbreaks may occur at the original site of the infection or in proximity ...
RESULTS. From 1993 through 1997, 878 (32%) of the 2,751 outbreaks reported to CDC had a known etiology; these outbreaks accounted for 50,788 (59%) of 86,058 infections (Table 1). Of the 878 outbreaks with a known etiology, 75% (86% of infections) were caused by bacterial pathogens, 17% (1% of infections) by chemical agents, 6% (8% of infections) by viruses, and 2% (5% of infections) by parasites. In most (68%) outbreaks, the etiology was not determined. The incubation period was reported for 1,406 (75%) of the 1,873 outbreaks that had an unknown etiology; in 44 (3%) outbreaks, the incubation period was less than 1 hour; in 428 (30%) outbreaks, 1-7 hours; in 285 (20%) outbreaks, 8-14 hours; and in 649 outbreaks (46%), greater than or equal to 15 hours.. Local investigators may report factors they believe contributed to the outbreak. For each of the years from 1993 through 1997, the most commonly reported food preparation practice that contributed to foodborne disease was improper holding ...
This report published in Communicable Diseases Intelligence, Volume 28, Number 2 provides and analysis of foodborne disease outbreaks in Australia from 1995 to 2000. Health agencies are increasingly conducting systematic reviews of foodborne disease outbreak investigations to develop strategies to prevent future outbreaks.
WEDNESDAY, Aug. 21, 2019 (HealthDay News) -- Texas cities are in danger of major measles outbreaks because an alarming number of school kids are unvaccinated, researchers warn.. Vaccination rates in the state have declined since 2003 and a computer simulation by University of Pittsburgh researchers found that an additional 5% decrease could increase the size of a measles outbreak by as much as 4,000% in some cities.. At current vaccination rates, theres a significant chance of an outbreak involving more than 400 people right now in some Texas cities, study lead author David Sinclair said in a university news release. Hes a postdoctoral researcher in Pitts School of Public Health.. We forecast that a continuous reduction in vaccination rates would exponentially increase possible outbreak sizes, he added.. At current vaccination rates, the simulation estimates that measles outbreaks of more than 400 cases could occur in Austin and Dallas-Fort Worth. This is because some schools have ...
Between 1985 and 1994 there have been four large-scale outbreaks of measles at the Principia schools for Christian Scientists in the St. Louis area. The 1985 outbreak at Principia College had 128 confirmed or probable cases of measles with three deaths of young people from complications of measles. In 1989 there were 88 cases of measles at the Principia K-12 school and 12 measles cases at Principia College..

The ability to detect disease outbreaks in their early stages is a key component of efficient disease control and prevention. With the increased availability of electronic health-care data and spatio-temporal analysis techniques, there is great potential to develop algorithms to enable more effective disease surveillance. However, to ensure that the algorithms are effective they need to be evaluated. The objective of this research was to develop a transparent user-friendly method to simulate spatial-temporal disease outbreak data for outbreak detection algorithm evaluation. A state-transition model which simulates disease outbreaks in daily time steps using specified disease-specific parameters was developed to model the spread of infectious diseases transmitted by person-to-person contact. The software was developed using the MapBasic programming language for the MapInfo Professional geographic information system environment. The simulation model developed is a generalised and flexible model which
Foodborne disease outbreaks caused by imported food appeared to rise in 2009 and 2010, and nearly half of the outbreaks implicated foods imported from areas which previously had not been associated with outbreaks, according to research from the Centers for Disease Control and Prevention, presented today at the International Conference on Emerging Infectious Diseases in Atlanta.. Its too early to say if the recent numbers represent a trend, but CDC officials are analyzing information from 2011 and will continue to monitor for these outbreaks in the future, said Hannah Gould, Ph.D., an epidemiologist in CDCs Division of Foodborne, Waterborne and Environmental Diseases and the lead author.. CDC experts reviewed outbreaks reported to CDCs Foodborne Disease Outbreak Surveillance System from 2005-2010 for implicated foods that were imported into the United States. During that five-year period, 39 outbreaks and 2,348 illnesses were linked to imported food from 15 countries. Of those outbreaks, ...
In 2007, a waterborne outbreak of Cryptosporidium hominis infection occurred in western Ireland, resulting in 242 laboratory-confirmed cases and an uncertain number of unconfirmed cases. A boil water notice was in place for 158 days that affected 120,432 persons residing in the area, businesses, visitors, and commuters. This outbreak represented the largest outbreak of cryptosporidiosis in Ireland. The purpose of this study was to evaluate the cost of this outbreak. We adopted a societal perspective in estimating costs associated with the outbreak. Economic cost estimated was based on totaling direct and indirect costs incurred by public and private agencies. The cost of the outbreak was estimated based on 2007 figures. We estimate that the cost of the outbreak was >€19 million (≈€120,000/day of the outbreak). The US dollar equivalent based on todays exchange rates would be $22.44 million (≈$142,000/day of the outbreak). This study highlights the economic need for a safe drinking water
A large-scale multiple surveillance system for infectious disease outbreaks has been in operation in England and Wales since the early 1990s. Changes to the statistical algorithm at the heart of the system were proposed and the purpose of this paper is to compare two new algorithms with the original algorithm. Test data to evaluate performance are created from weekly counts of the number of cases of each of more than 2000 diseases over a twenty-year period. The time series of each disease is separated into one series giving the baseline (background) disease incidence and a second series giving disease outbreaks. One series is shifted forward by twelve months and the two are then recombined, giving a realistic series in which it is known where outbreaks have been added. The metrics used to evaluate performance include a scoring rule that appropriately balances sensitivity against specificity and is sensitive to variation in probabilities near 1. In the context of disease surveillance, a scoring rule can
The Council to Improve Foodborne Outbreak Response (CIFOR) released the second edition of the CIFOR Guidelines for Foodborne Disease Outbreak Response in April of 2014. The Guidelines describe the overall approach to foodborne disease outbreak response (including preparation, surveillance and outbreak detection, cluster and outbreak investigation, and control) and provide recommended practices in each of these areas to help agencies and jurisdictions improve local foodborne disease outbreak response. The Guidelines capture the approaches (and genius) of some of the great foodborne disease investigation and control programs in this country, portraying their successful practices in black and white for all to see (and learn from). The Guidelines are chockfull of recommended activities that can help every program in the country (big and small) be one of the greats!. But the Guidelines were not made for light (or bedtime) reading (nor for finding the practices that will help improve your program on ...
Olive leaf extract has been known as a remedy for fighting all types of viruses, including herpes simplex virus. Olive leaf extract consists of the compound of oleurpein which is tested to kill various viruses. This is a strong compound lied in olive leaves and trunk which protect the plant from parasites. Herpes flares up when your immune system weakens or when you are stressed, because your body does not produce enough protein. Olive oil extract is capable of boosting the immune system to produce sufficient protein which will inhibit the virus from out breaking. Oleurpein is the main content of olive leaf extract which boosts immune system to fight herpes simplex virus which may cause both labial and genital herpes. Although the substance is not proven yet to eliminate herpes virus permanently, this is useful for preventing the virus from causing major outbreak. This major outbreak may cause painful blisters around the mouth which are accompanied by itching. In severe genital herpes, this ...
The first step in the investigation is, of course, detecting that an outbreak has actually occurred. Public health agencies usually discover an outbreak by monitoring the results of the foodborne illness surveillance systems in place. If surveillance system reporting shows that an unusually large number of people in a given area fell ill due to the same pathogen, public health officials may deem this irregularity a cluster. If the individuals in the cluster all consumed a common food product linked to the illness, an outbreak is determined.. A cluster, suggestive of an outbreak, can be identified in several ways. Informal reporting can help public health officials determine a cluster that specifically identifies an outbreak and the food industry source responsible. Informal reporting occurs, for example, when individuals from a community inform their local health agency of several instances of foodborne illnesses occurring after exposure to a common food source, such as when a group of friends ...

At least 13 people in eight states have died after eating cantaloupe contaminated with listeria, in the deadliest outbreak of food-borne illness in the United States in more than a decade, public health officials said on Tuesday. ... The outbreak appeared to be the third worst in the United States attributed to any form of food-borne illness, in terms of the number of deaths, since the C.D.C. began regularly tracking such outbreaks in the early 1970s. The deadliest outbreak in the United States since then occurred in 1985, when a wave of listeria illness, linked to Mexican-style fresh cheese, swept through California. A federal database says 52 deaths were attributed to the outbreak, but news reports at the time put the number as high as 84. The second-deadliest outbreak was in 1998 and 1999, when there were at least 14 deaths and four miscarriages or stillbirths in a listeria outbreak linked to hot dogs and delicatessen meats. Some sources put the death toll in that outbreak as high as 21 ...
Here, we have presented an investigation of two outbreaks of MDR K. pneumoniae infections in adjoining high‐dependency paediatric units in a hospital in Nepal. The outbreaks were characterised by a high proportion of bloodstream infections and a high case‐fatality rate. We used WGS in an attempt to characterise strain circulation and diversity in this hospital, and comparative genomics to identify genetic traits that may be associated with the disease phenotype and the persistence of these strains. The notable advances highlighted in this study, in comparison to previous investigations of hospital outbreaks of K. pneumoniae, are the use of the large‐scale WGS data to deduce the bacterial isolates involved in the outbreaks and to use these data to retrospectively define the scope of outbreak strains across the hospital over a protracted period. These approaches have permitted us to interrogate these serious hospital outbreaks of K. pneumoniae with a degree of resolution that would be ...
In an op-ed piece published yesterday in the Oregonian, the Oregon state health department claims that a substantial proportion of cases of the vaping-associated respiratory illness outbreak are caused not by THC/CBD vaping, but by nicotine-containin
Apparently, there is a Faith Healer [who] Convinces Followers To Never Vaccinate, [and] Now Church [is] The Center Of Measles Outbreak The Eagle Mountain International Church in Newark, Texas, run by Kenneth Copeland Ministries, has long been a strong anti-vaccination stronghold. Now, it is the epicenter of a major outbreak of Measles in the United States.
The production process of the swabs was described as follows: The foam rubber heads and sticks were glued together manually in private homes of employees who were following moderate hygiene guidelines.. One batch of moisturizing liquid consisted of: Tap water (147 liters), 96% ethanol (3 litres), Glycerol (16 litres) and Vademecum, a commercially available mouth rinse (6 litres). The main ingredients of the mouth rinse are ethanol (44%) and sodium benzoate (5.25%). The final concentration in the Dent-O-Sept moisturizing liquid was calculated to be 2.3% ethanol; 9.3% glycerol and 0.18% sodium benzoate [25].. A new batch of the liquid was prepared in the following way every week of production: The tap water was filled into a large steel tank with a lid on Friday, and then heated to 95°C the following day in an automated but uncontrolled process (Figure 2). On Monday the other ingredients were added and the solution stirred manually with a steel rod.. Packing, moisturizing and sealing of the swabs ...

Expect even more measles outbreaks in the United States in coming years, public health experts say, thanks to overseas epidemics and growing misinformation efforts by anti-vaccination activists.. Outbreaks of the highly contagious virus are now active in 20 states, with 555 confirmed cases in the US this year alone, according to the CDC. Thats well on track to exceed 2014s record of 667 cases, the highest number recorded since the disease was declared domestically eradicated in 2000.. All of the new US outbreaks originally derived from infections transmitted by travelers - either visitors from overseas, or US residents who went abroad. Every case we have now is associated with travel, Thomas Clark, deputy director of the CDCs viral diseases division, told BuzzFeed News. And with measles cases now surging outside of the US too - seeing a 300% global increase this year compared to last - we are likely to see more cases here, public health experts say.. It is unfortunately the new normal, ...
The CDC continues to interview sick people in the United States to determine what they ate in the week before their illness started.. Based on that information, officials say that ill persons in this outbreak are not more likely than healthy people to have eaten romaine lettuce.. An FDA spokesperson later confirmed this position to Consumer Reports: This work is ongoing.. This is a unsafe strain of E. coli that can cause severe illness and even death, said Hallorans statement. A spokeswoman for the health department Thursday said there was one case in the state linked to the current outbreak involving leafy salad greens. However, an eerily similar outbreak in the U.S.is still being investigated by the Centers for Disease Control and Prevention and the U.S. Food and Drug Administration. Because of these reporting delays, more time is needed before CDC can say the outbreak in the United Stated is over.. Romaine lettuce might be the culprit of a recent E. coli outbreak, but the CDC says it ...
The outbreak that included 119 cases including 40 deaths last November has increased to 213 cases and 57 fatalities and in light of the recent tropical storm and flooding on Madagascar, which has displaced tens of thousands of people and untold numbers of rats,the risk of more plague is something to be concerned about.. Chan said of the Madagascar plague outbreak:. This is the kind of geographically focused and readily manageable outbreak that WHO was designed to contain. Plague is endemic in Madagascar, where seasonal outbreaks are amplified by the dual forces of poverty and unplanned urbanization. Detected early, the disease responds well to treatment. Researchers at the countrys Institut Pasteur, supported by WHO, have developed a cheap and reliable diagnostic test that delivers results in 15 minutes.. But the outbreak that started last November has some disturbing dimensions. The fleas that transmit this ancient disease from rats to humans have developed resistance to the first-line ...
In our paper (1), we analyzed isolates from the Escherichia coli O104:H4 outbreaks in Germany and France in May to July 2011. We concluded that, although the German outbreak was larger, the German isolates represent a clade within the greater diversity of the French outbreak. We proposed several hypotheses to explain these findings, including that the lineage leading to the German outbreak went through a narrow bottleneck that purged diversity. Guy et al. (2) report the genomes of eight additional E. coli O104:H4 isolates sampled from the German outbreak. By focusing on the numbers of SNPs in their samples, they suggest that the German outbreak is more diverse than we reported and is similar to the French outbreak. In fact, Guy et al.s data (2) strongly support our conclusion that the German outbreak represents a clade within the diversity ...
Arizona-based meat producer JBS Tolleson, Inc. is recalling 6,500,966 pounds of various raw, non-intact beef products due to an outbreak of salmonella, the United States Department of Agricultures Food Safety and Inspection Service announced Thursday.. The recalled products may be contaminated with salmonella, according to the FSIS.. The recall was issued after health officials identified JBS as the common supplier of raw ground beef products found to be the probable source of reported salmonella illnesses. Fifty-seven cases of salmonella illness linked to this outbreak were reported in 16 U.S. states between Aug. 5 and Sept. 6.. The USDAs FSIS was first notified of the possible outbreak in September. Receipts and shopper cards from eight patients helped identify the source of the outbreak, investigators said.. Symptoms of salmonella usually begin 12 to 72 hours after consuming contaminated food. These can include diarrhea, abdominal cramps and fever that last between four and seven days. ...
Studying the geographical distribution of diseases over the internet is a hot trending topic in digital epidemiology. Epidemiologists have begun to use online data (such as Twitter trends) to track the activity levels of infectious diseases, as social media is a good method of measuring public awareness to disease outbreaks.A recently published article in Infectious Diseases of Poverty is the first to document the online Chinese communitys reaction to a SARS-like virus (MERS-CoV) in the Middle East and Europe in 2012, compared to their reaction to the bird flu (H7N9) outbreak in China in 2013. Data was collected via Weibo (a Chinese version of Twitter) by the University of Hong Kongs Weiboscope project.This article showed that the reaction on Weibo to the H7N9 outbreak within China was two orders of magnitude stronger than the reaction to the MERS-CoV disease outbreak in the Middle East and Europe. This data indicates that the online communitys reaction is more profound when the disease ...
This report documents turtles as an important source of pediatric salmonellosis through identification and investigation of an unprecedented number of multistate Salmonella outbreaks associated with exposure to small turtles in a 29-month period. Despite the 1975 federal ban against the sale of small pet turtles, these animals are readily available to a public that is largely unaware of the association between reptiles and Salmonella. Turtles from 1 of the 8 outbreaks were traced to 2 Louisiana turtle farms; samples from breeding ponds at 1 of these farms yielded the outbreak strain. To our knowledge, this is the first time since 1984 that turtles implicated in Salmonella outbreaks have been traced back to the farm of origin, offering a rare opportunity to stop the distribution of turtles causing human illnesses at the source. Traceback for other outbreaks was hindered by the high frequency of purchases from difficult-to-trace vendors, which also pose challenges to turtle ban enforcement and ...
Queens University Chair of the Division of Infectious Diseases Gerald Evans is available to comment on the World Health Organization confirming the deadly Ebola virus outbreak in Congo is now an international health emergency. More than 1,600 people have died since August in the second-worst outbreak of the disease in history.. I agree with the WHO declaration that the outbreak of Ebola virus disease in the DRC is a public health threat of international concern, says Dr. Evans. This outbreak that started nearly a year ago, is now the second largest outbreak of this killer virus following the outbreak in west Africa, which caused over 11,000 deaths from 2014-16. Its arrival in the city of Goma with a population of over two million people has the potential to cause catastrophic spread of Ebola in Africa and beyond. As a global community, we need to take this threat very seriously.. Dr. Evans is a former President of the Association of Medical Microbiology and Infectious Disease (AMMI) ...
India has put 26 people in isolation with bird flu symptoms and hundreds more people are being monitored, officials said on Friday as Pakistan and Thailand reported outbreaks of bird flu in poultry. India is battling its worst outbreak of avian influenza, which has spread to 13 of West Bengals 19 districts. The densely populated state is adjacent to Bangladesh, itself trying to control a major outbreak of bird flu, and has millions of backyard fowl. India has not reported any human infection of the H5N1 bird flu virus in its four outbreaks of avian influenza since 2006.. The preliminary tests for bird flu are negative, but more tests are being conducted and the list of sick people reviewed every day, R.S. Shukla, a senior health official, told Reuters.. To the west in neighboring Pakistan, authorities said bird flu had been detected at a poultry farm on the outskirts of its biggest city, Karachi. But officials said on Friday there was no likelihood of any human infection. In Thailand, the ...
The Ebola outbreak in West Africa has already killed 600 people. The outbreak occurred this spring, but a new study shows that the virus may have been affecting people in the region for years before the outbreak.. According to the study, there was a mysterious illness affecting people in West Africa years before the outbreak. The illness was likely the Ebola virus. Although blood samples were taken from most of the people treated for the illness, none of them were tested for Ebola.. Researchers are now testing the blood samples to see if the patients were indeed suffering from the Ebola virus. The test samples were over seven years old, but still potentially dangerous. Researchers had to heat treat them to help make them safe before they could be tested.. It had been circulating there for a long time, said Randal Schoepp of the U.S. Army Medical Research Institute of Infectious Diseases. It just hadnt gotten out of control or the right conditions werent there.. ...
What causes cholera?. Cholera is transmitted through poor hygiene and sanitation. It is no wonder that areas of natural disasters that result in disruption of water and sanitation systems are major outbreak areas of cholera. Other hotspots for cholera outbreaks are overcrowded refugee camps where displaced human populations are temporary accommodated and urban slums. These facilities, too, have inadequate clean water and sanitation system.. Strangely enough, it is not the infection itself that usually kills cholera victims but rather the dehydration resulting from severe diarrhea and vomiting.. The Haitian capital city Port-au-Prince is a classic example of an urban area where cholera can break out.. Pandemic cholera. Like the flu, cholera has also caused pandemics in the past. WHO gives the following historical background:. ...
The CIFOR protocol for investigating foodborne illnesses provides guidance and direction for the regulatory and regulated communities. During a foodborne illness outbreak, time is of the essence in order to identify the offending food product and to remove it from the market place. To facilitate and ensure correct information is obtained in a timely fashion, a consistent approach to investigating foodborne illness outbreaks is crucial.. By using these CIFOR Guidelines and Tools, Industry can take an active and educated role in the outbreak response and investigation, reducing the impact to the public and their business. A fully coordinated investigation can then proceed more quickly and accurately, yielding more dependable results that are in the interest of public health while limiting impact to the involved industry.. The benefits of having a uniform approach include:. 1. The CIFOR Guidelines are a Best Practices document.. 2. Investigation training is simplified by having everyone training to ...

The Municipality of Walvis Bay would like to notify residents of the outbreak of Hepatitis E in the Walvis Bay District. In November 2017, the Ministry of Health and Social Services declared a Hepatitis E outbreak in Windhoek and since then cases have been reported in other regions. In the Erongo region, the outbreak has been reported in Swakopmund, Omaruru, Henties Bay and Walvis Bay as stated by the Ministry of Health and Social Services. More than 5 laboratory confirmed cases in a month constitute an outbreak and Walvis Bay has reported more than 5 laboratory confirmed cases. The Municipality of Walvis Bay took immediate action in response and launch-ed campaigns to create awareness on food safety and good personal hygiene practices among residents and informal food traders in Walvis Bay. To date, the campaigns have been a great success as the public and informal food traders welcomed the information sharing and were very eager to participate ...
Mohawk College students are asking whether an outbreak similar to the one that recently hit Humber College could happen here. The norovirus outbreak at Humber sickened over 200 students with flu-like symptoms.. My friends at Humber became extremely ill and one of them actually had to be hospitalized, said Mohawk College student Ryan Ryu.. Colleges around the GTA are being asked what they are doing in the wake of the norovirus outbreak at Humber. Jay Robb, Mohawk Colleges director of communications, said the school is taking precautions but wouldnt have handled an outbreak any differently.. As always we keep close tabs on potential outbreaks among our students, faculty and staff, said Robb. Robb also adds that no outbreaks similar to the one at Humber have happened at Mohawk in more than a decade.. But many students and parents remain concerned as to what would happen if Mohawk were to have an outbreak and what it would take for a post-secondary institution to shut down after an ...

The evolutionary origins of the influenza A(H1N1)pdm09 virus that caused the first outbreak of the 2009 pandemic in Mexico remain unclear, highlighting the lack of swine surveillance in Latin American countries. Although Brazil has one of the largest swine populations in the world, influenza was not thought to be endemic in Brazils swine until the major outbreaks of influenza A(H1N1)pdm09 in 2009. Through phylogenetic analysis of whole-genome sequences of influenza viruses of the H1N1, H1N2, and H3N2 subtypes collected in swine in Brazil during 2009-2012, we identified multiple previously uncharacterized influenza viruses of human seasonal H1N2 and H3N2 virus origin that have circulated undetected in swine for more than a decade. Viral diversity has further increased in Brazil through reassortment between co-circulating viruses, including A(H1N1)pdm09. The circulation of multiple divergent hemagglutinin lineages challenges the design of effective cross-protective vaccines and highlights the ...
