RESUMO
Despite food technology advancements, food safety policies and alert systems, foodborne diseases are still a relevant concern for consumers and public health authorities, with great impacts on the economy and the society. Evaluating the cost of foodborne diseases may support the design and the implementation of policy interventions. This paper proposes a simple method for cost identification of foodborne diseases, accessible to researchers and practitioners who are not specialist in economics. The method is based on the assumption that epidemiological and economic models can be integrated to understand how the burden of disease determines costs in a wider socio-economic perspective. Systems thinking and interdisciplinary approach are the pivotal conceptual tools of the method. Systems thinking allows for the understanding of the complex relationships working among the elementary units of a system (e.g. wildlife, bred animals, consumers, environment, agro-food industry) in the occurrence of a health problem such foodborne diseases. Complex systemic relationships usually cross the traditional boundaries of scientific knowledge (human medicine, veterinary science, economics) and sectoral institutional responsibilities (e.g. ministry of health, ministry of agriculture). For these reasons more scientific disciplines, institutional competences and social bodies need to work together to face complex health problems, in an interdisciplinary framework. The first step of the proposed method is the identification of the potential cost of the disease. To this aim, the authors first focus on the links between epidemiological and economic models, based on the fact that foodborne diseases, likewise other diseases, hit people's and animals' aptitude to produce utility and goods for the society (e.g. wellbeing, revenue, safe food). These utility losses are real economic costs. Then they show how simple economic models, such as the food supply chain, can help understand the way costs spread across the economic sectors and the society. It should be underlined that the authors adopt already existing and well rooted scientific tools, focusing in particular that their integration in an interdisciplinary framework can effectively contribute to increase the understanding of complex health problems in a viable way.

OBJECTIVES: To describe a cross-border foodborne outbreak of Shigella sonnei that occurred in Ireland and Northern Ireland (NI) in December 2016 whilst also highlighting the valuable roles of sales data and international collaboration in the investigation and control of this outbreak. STUDY DESIGN: A cross-border outbreak control team was established to investigate the outbreak. METHODS: Epidemiological, microbiological, and environmental investigations were undertaken. Traditional analytical epidemiological studies were not feasible in this investigation. The restaurant chain provided sales data, which allowed assessment of a possible increased risk of illness associated with exposure to a particular type of heated food product (product A). RESULTS: Confirmed cases demonstrated sole trimethoprim resistance: an atypical antibiogram for Shigella isolates in Ireland. Early communication and the sharing of information within the outbreak control team facilitated the early detection of the international dimension of this outbreak. A joint international alert using the European Centre for Disease Control's confidential Epidemic Intelligence Information System for Food- and Waterborne Diseases and Zoonoses (EPIS-FWD) did not reveal further cases outside of the island of Ireland. The outbreak investigation identified that nine of thirteen primary case individuals had consumed product A from one of multiple branches of a restaurant chain located throughout the island of Ireland. Product A was made specifically for this chain in a food production facility in NI. S. sonnei was not detected in food samples from the food production facility. Strong statistical associations were observed between visiting a branch of this restaurant chain between 5 and 9 December 2016 and eating product A and developing shigellosis. CONCLUSIONS: This outbreak investigation highlights the importance of international collaboration in the efficient identification of cross-border foodborne outbreaks and the value of using sales data as the analytical component of such studies.

Burden of disease metrics are increasingly established to prioritize food safety interventions. We estimated the burden of disease caused by seven foodborne pathogens in Denmark in 2017: Campylobacter, Salmonella, Shiga toxin-producing Escherichia coli, norovirus, Yersinia enterocolitica, Listeria monocytogenes, and Toxoplasma gondii. We used public health surveillance data and scientific literature to estimate incidence, mortality, and total disability-adjusted life year (DALY) of each, and linked results with estimates of the proportion of disease burden that is attributable to foods. Our estimates showed that Campylobacter caused the highest burden of disease, leading to a total burden of 1709 DALYs (95% uncertainty interval [UI] 1665-1755), more than threefold higher than the second highest ranked pathogen (Salmonella: 492 DALYs; 95% UI 481-504). Campylobacter still led the ranking when excluding DALYs attributable to nonfoodborne routes of exposure. The total estimated incidence was highest for norovirus, but this agent ranked sixth when focusing on foodborne burden. Salmonella ranked second in terms of foodborne burden of disease, followed by Listeria and Yersinia. Foodborne congenital toxoplasmosis was estimated to cause the loss of â¼100 years of healthy life, a burden that was borne by a low number of cases in the population. The ranking of foodborne pathogens varied substantially when based on reported cases, estimated incidence, and burden of disease estimates. Our results reinforce the need to continue food safety efforts throughout the food chain in Denmark, with a particular focus on reducing the incidence of Campylobacter infections.

Cost of foodborne illness (CoFI) estimates provide estimates of the overall impact of foodborne illnesses, including hospitalizations, long-term complications, and deaths. CoFI estimates are needed in countries that require cost-benefit analysis as part of the process of adopting new regulations, as is the case in the United States. Monetary estimates of the impact of disease also provide a meaningful way of communicating with the public about the impact of foodborne disease. In 2014, researchers at the U.S. Department of Agriculture, Economic Research Service (ERS), published CoFI estimates for 15 pathogens that account for roughly 95% of illnesses and deaths from the 31 major foodborne pathogens included in the Centers for Disease Control and Prevention (CDC) foodborne disease incidence estimates. ERS is currently updating their estimates to include all 31 known pathogens and unspecific agents included in CDC incidence estimates. CoFI estimates are based on quantitative models of the health outcomes people experience as a result of these illnesses and an assessment of the costs associated with these health outcomes. Research on the incidence of foodborne disease provides a starting point for this disease modeling, but it usually must be supplemented by other additional synthesis of research on acute complications and long-term health outcomes of different foodborne diseases. As part of its current work revising CoFI estimates, ERS convened a workshop attended by leading foodborne disease public health scientists to discuss how changes in scientific research on the incidence and outcomes of foodborne illnesses should inform the next revision of ERS's CoFI estimates. This article presents a summary, based on discussion at this workshop, of the state of scientific research available to inform updated economic modeling of the CoFI in the United States.

BACKGROUND/PURPOSE: Foodborne disease is a global health problem. We aim to provide the first national estimate on disease burden from foodborne illnesses in Taiwan. METHODS: We adopted the World Health Organization (WHO) Foodborne Disease Burden Epidemiology Reference Group (FERG) methodology framework, and used a hazard-based incidence approach to calculate disability-adjusted life year (DALY) lost to foodborne diseases. Estimated annual incidences and associated medical costs are based on the National Health Insurance research database. We redistributed incidence of unspecified acute gastroenteritis to specific foodborne pathogens, using reported bacteria, virus, parasite survey results in such cases as the reference. The percentage of foodborne illnesses not seeking medical attention is based on data reported from a nationwide survey. RESULTS: During 2012-2015, 3,895,914 (90% confidence interval [CI]: 3,493,530-4,442,690) foodborne illnesses (1,445,384 sought medical care, with 50 deaths) occurred annually, which caused a total loss of 4974 (90%CI: 4671-5367) DALYs in Taiwan. The annual medical cost was NT$1.3 billion. Young (<5 years) children had the highest incidence. Among the 53% of foodborne illnesses cases with identifiable causal microorganisms, non-typhoid Salmonella, norovirus, and Vibrio parahaemolyticus were leading pathogens (annual foodborne incidence: 185,977, 157,656, and 99,351, respectively). Cases caused by non-typhoid Salmonella peaked in summer, while that caused by norovirus peaked in winter. CONCLUSION: Foodborne illnesses cause a substantial disease burden in Taiwan. Establishment of active surveillance and investigation mechanisms for the leading foodborne pathogens is warranted.

Salmonellosis, campylobacteriosis and listeriosis are food-borne diseases. We estimated and forecasted the number of cases of these three diseases in Belgium from 2012 to 2020, and calculated the corresponding number of disability-adjusted life years (DALYs). The salmonellosis time series was fitted with a Bai and Perron two-breakpoint model, while a dynamic linear model was used for campylobacteriosis and a Poisson autoregressive model for listeriosis. The average monthly number of cases of salmonellosis was 264 (standard deviation (SD): 86) in 2012 and predicted to be 212 (SD: 87) in 2020; campylobacteriosis case numbers were 633 (SD: 81) and 1,081 (SD: 311); listeriosis case numbers were 5 (SD: 2) in 2012 and 6 (SD: 3) in 2014. After applying correction factors, the estimated DALYs for salmonellosis were 102 (95% uncertainty interval (UI): 8-376) in 2012 and predicted to be 82 (95% UI: 6-310) in 2020; campylobacteriosis DALYs were 1,019 (95% UI: 137-3,181) and 1,736 (95% UI: 178-5,874); listeriosis DALYs were 208 (95% UI: 192-226) in 2012 and 252 (95% UI: 200-307) in 2014. New actions are needed to reduce the risk of food-borne infection with Campylobacter spp. because campylobacteriosis incidence may almost double through 2020.

Hospitalized salmonellosis patients with concurrent chronic conditions may be at increased risk for adverse outcomes, increasing the costs associated with hospitalization. Identifying important modifiable risk factors for this predominantly foodborne illness may assist hospitals, physicians, and public health authorities to improve management of these patients. The objectives of this study were to (1) quantify the burden of salmonellosis hospitalizations in the United States, (2) describe hospitalization characteristics among salmonellosis patients with concurrent chronic conditions, and (3) examine the relationships between salmonellosis and comorbidities by four hospital-related outcomes. A retrospective analysis of salmonellosis discharges was conducted using the Agency for Healthcare Research and Quality's Nationwide Inpatient Sample for 2011. A supplemental trend analysis was performed for the period 2000-2011. Hospitalization characteristics were examined using multivariable regression modeling, with a focus on four outcome measures: in-hospital death, total amount billed by hospitals for services, length of stay, and disease severity. In 2011, there were 11,032 total salmonellosis diagnoses; 7496 were listed as the primary diagnosis, with 86 deaths (case-fatality rate = 1.2%). Multivariable regression analyses revealed a greater number of chronic conditions (≥4) among salmonellosis patients was associated with higher mean total amount billed by hospitals for services, longer length of stay, and greater disease severity (p ≤ 0.05). From 2000 to 2011, hospital discharges for salmonellosis increased by 27.2%, and the mean total amount billed by hospitals increased nearly threefold: $9,777 (2000) to $29,690 (2011). Observed increases in hospitalizations indicate the burden of salmonellosis remains substantial in the United States. The positive association between increased number of chronic conditions and the four hospital-related outcomes affirms the need for continual healthcare and public health investments to prevent and control this disease in vulnerable groups.

BACKGROUND: Foodborne diseases are globally important, resulting in considerable morbidity and mortality. Parasitic diseases often result in high burdens of disease in low and middle income countries and are frequently transmitted to humans via contaminated food. This study presents the first estimates of the global and regional human disease burden of 10 helminth diseases and toxoplasmosis that may be attributed to contaminated food. METHODS AND FINDINGS: Data were abstracted from 16 systematic reviews or similar studies published between 2010 and 2015; from 5 disease data bases accessed in 2015; and from 79 reports, 73 of which have been published since 2000, 4 published between 1995 and 2000 and 2 published in 1986 and 1981. These included reports from national surveillance systems, journal articles, and national estimates of foodborne diseases. These data were used to estimate the number of infections, sequelae, deaths, and Disability Adjusted Life Years (DALYs), by age and region for 2010. These parasitic diseases, resulted in 48.4 million cases (95% Uncertainty intervals [UI] of 43.4-79.0 million) and 59,724 (95% UI 48,017-83,616) deaths annually resulting in 8.78 million (95% UI 7.62-12.51 million) DALYs. We estimated that 48% (95% UI 38%-56%) of cases of these parasitic diseases were foodborne, resulting in 76% (95% UI 65%-81%) of the DALYs attributable to these diseases. Overall, foodborne parasitic disease, excluding enteric protozoa, caused an estimated 23.2 million (95% UI 18.2-38.1 million) cases and 45,927 (95% UI 34,763-59,933) deaths annually resulting in an estimated 6.64 million (95% UI 5.61-8.41 million) DALYs. Foodborne Ascaris infection (12.3 million cases, 95% UI 8.29-22.0 million) and foodborne toxoplasmosis (10.3 million cases, 95% UI 7.40-14.9 million) were the most common foodborne parasitic diseases. Human cysticercosis with 2.78 million DALYs (95% UI 2.14-3.61 million), foodborne trematodosis with 2.02 million DALYs (95% UI 1.65-2.48 million) and foodborne toxoplasmosis with 825,000 DALYs (95% UI 561,000-1.26 million) resulted in the highest burdens in terms of DALYs, mainly due to years lived with disability. Foodborne enteric protozoa, reported elsewhere, resulted in an additional 67.2 million illnesses or 492,000 DALYs. Major limitations of our study include often substantial data gaps that had to be filled by imputation and suffer from the uncertainties that surround such models. Due to resource limitations it was also not possible to consider all potentially foodborne parasites (for example Trypanosoma cruzi). CONCLUSIONS: Parasites are frequently transmitted to humans through contaminated food. These estimates represent an important step forward in understanding the impact of foodborne diseases globally and regionally. The disease burden due to most foodborne parasites is highly focal and results in significant morbidity and mortality among vulnerable populations.

BACKGROUND: Foodborne diseases are important worldwide, resulting in considerable morbidity and mortality. To our knowledge, we present the first global and regional estimates of the disease burden of the most important foodborne bacterial, protozoal, and viral diseases. METHODS AND FINDINGS: We synthesized data on the number of foodborne illnesses, sequelae, deaths, and Disability Adjusted Life Years (DALYs), for all diseases with sufficient data to support global and regional estimates, by age and region. The data sources included varied by pathogen and included systematic reviews, cohort studies, surveillance studies and other burden of disease assessments. We sought relevant data circa 2010, and included sources from 1990-2012. The number of studies per pathogen ranged from as few as 5 studies for bacterial intoxications through to 494 studies for diarrheal pathogens. To estimate mortality for Mycobacterium bovis infections and morbidity and mortality for invasive non-typhoidal Salmonella enterica infections, we excluded cases attributed to HIV infection. We excluded stillbirths in our estimates. We estimate that the 22 diseases included in our study resulted in two billion (95% uncertainty interval [UI] 1.5-2.9 billion) cases, over one million (95% UI 0.89-1.4 million) deaths, and 78.7 million (95% UI 65.0-97.7 million) DALYs in 2010. To estimate the burden due to contaminated food, we then applied proportions of infections that were estimated to be foodborne from a global expert elicitation. Waterborne transmission of disease was not included. We estimate that 29% (95% UI 23-36%) of cases caused by diseases in our study, or 582 million (95% UI 401-922 million), were transmitted by contaminated food, resulting in 25.2 million (95% UI 17.5-37.0 million) DALYs. Norovirus was the leading cause of foodborne illness causing 125 million (95% UI 70-251 million) cases, while Campylobacter spp. caused 96 million (95% UI 52-177 million) foodborne illnesses. Of all foodborne diseases, diarrheal and invasive infections due to non-typhoidal S. enterica infections resulted in the highest burden, causing 4.07 million (95% UI 2.49-6.27 million) DALYs. Regionally, DALYs per 100,000 population were highest in the African region followed by the South East Asian region. Considerable burden of foodborne disease is borne by children less than five years of age. Major limitations of our study include data gaps, particularly in middle- and high-mortality countries, and uncertainty around the proportion of diseases that were foodborne. CONCLUSIONS: Foodborne diseases result in a large disease burden, particularly in children. Although it is known that diarrheal diseases are a major burden in children, we have demonstrated for the first time the importance of contaminated food as a cause. There is a need to focus food safety interventions on preventing foodborne diseases, particularly in low- and middle-income settings.

Illness and death from diseases caused by contaminated food are a constant threat to public health and a significant impediment to socio-economic development worldwide. To measure the global and regional burden of foodborne disease (FBD), the World Health Organization (WHO) established the Foodborne Disease Burden Epidemiology Reference Group (FERG), which here reports their first estimates of the incidence, mortality, and disease burden due to 31 foodborne hazards. We find that the global burden of FBD is comparable to those of the major infectious diseases, HIV/AIDS, malaria and tuberculosis. The most frequent causes of foodborne illness were diarrheal disease agents, particularly norovirus and Campylobacter spp. Diarrheal disease agents, especially non-typhoidal Salmonella enterica, were also responsible for the majority of deaths due to FBD. Other major causes of FBD deaths were Salmonella Typhi, Taenia solium and hepatitis A virus. The global burden of FBD caused by the 31 hazards in 2010 was 33 million Disability Adjusted Life Years (DALYs); children under five years old bore 40% of this burden. The 14 subregions, defined on the basis of child and adult mortality, had considerably different burdens of FBD, with the greatest falling on the subregions in Africa, followed by the subregions in South-East Asia and the Eastern Mediterranean D subregion. Some hazards, such as non-typhoidal S. enterica, were important causes of FBD in all regions of the world, whereas others, such as certain parasitic helminths, were highly localised. Thus, the burden of FBD is borne particularly by children under five years old-although they represent only 9% of the global population-and people living in low-income regions of the world. These estimates are conservative, i.e., underestimates rather than overestimates; further studies are needed to address the data gaps and limitations of the study. Nevertheless, all stakeholders can contribute to improvements in food safety throughout the food chain by incorporating these estimates into policy development at national and international levels.

OBJECTIVE: To understand more about the relationship between economic deprivation, types of premises, food hygiene scores and rates of gastrointestinal illness in the UK. DESIGN: Data were extracted from the UK Food Standards Agency for about 300 000 UK premises which had hygiene scores based on visits from local authority food safety officers. These scores were analysed by type of premises, deprivation and local authority. Local authority-level average scores were mapped and compared with rates of laboratory-detected gastrointestinal illness from the Health Protection Agency. SETTING: UK. SUBJECTS: UK premises (n 311 458) from 341 local authority areas that sell or produce food. RESULTS: There was a modest but statistically significant relationship between average food hygiene score and deprivation, which was caused by deprived areas having more of the categories of premises with significantly lower hygiene scores; these were pub/club (n 40 525), restaurant/café/canteen (n 73 052), small retailer (n 42 932) and takeaway (n 36 708). No relationship was established between local authority average food hygiene scores and rates of laboratory-detected gastrointestinal illness; however, this result does not preclude a relationship between food hygiene and rates of gastrointestinal illnesses, as laboratory-detected illness rates make up only a small proportion of actual rates of illness in the community. CONCLUSIONS: Certain types of UK premises are more likely to have low hygiene scores, which means that they should be targeted more for enforcement. These types of premises are more prevalent in the most economically deprived areas.

We present an economic welfare-based method to estimate the health costs associated with foodborne illness caused by known viruses, bacteria, parasites, allergens, two marine biotoxins, and unspecified agents. The method generates health costs measured in both quality-adjusted life years and in dollars. We calculate the reduction in quality-adjusted life days caused by the illness and add reductions in quality-adjusted life years from any secondary effects that are estimated to occur. For fatal cases, we calculate the life years lost due to premature death. We add direct medical expenses to the monetary costs as derived from estimates of willingness to pay to reduce health risks. In total, we estimate that foodborne illness represents an annual burden to society of approximately $36 billion, with an average identified illness estimated to reduce quality-adjusted life days by 0.84, which is monetized and included in the average cost burden per illness of $3,630.

Vietnam is undergoing a rapid social and economic developments resulting in speedy urbanization, changes in methods for animal production, food marketing systems, and food consumption habits. These changes will have major impacts on human exposures to food poisoning. The present case study aimed to estimate hospitalization costs of foodborne diarrhea cases in selected health facilities in Vietnam. This is a facility-based cost-of-illness study conducted in seven health facilities in Northern Vietnam. All suspect cases of foodborne diarrhea, as diagnosed by doctors, who admitted to the studied health facilities during June-August, 2013 were selected. Costs associated with hospitalization for foodborne diseases were estimated from societal perspective using retrospective approach. We included direct and indirect costs of hospitalization of foodborne diarrhea cases. During the study period, 87 foodborne diarrhea cases were included. On average, the costs per treatment episode and per hospitalization day for foodborne diarrhea case were US$ 106.9 and US$ 33.6 respectively. Indirect cost (costs of times to patient, their relatives due to the patient's illness) made up the largest share (51.3%). Direct medical costs accounted for 33.8%; direct non-medical costs (patient and their relatives) represented 14.9%. Cost levels and compositions varied by level of health facilities. More attentions should be paid on prevention, control of foodborne diarrhea cases in Vietnam. Ensuring safety of food depends on efforts of everyone involved in food chain continuum, from production, processing, and transport to consumption.

Estimates of the economic costs associated with foodborne disease are important to inform public health decision-making. In 2008, 57 cases of listeriosis and 24 deaths in Canada were linked to contaminated delicatessen meat from one meat processing plant. Costs associated with the cases (including medical costs, nonmedical costs, and productivity losses) and those incurred by the implicated plant and federal agencies responding to the outbreak were estimated to be nearly $242 million Canadian dollars (CAD, 2008). Case costs alone were estimated at approximately $2.8 million (CAD, 2008) including loss of life. This demonstrates the considerable economic burden at both the individual and population levels associated with foodborne disease and foodborne outbreaks in particular. Foodborne outbreaks due to severe pathogens, such as Listeria monocytogenes and those that result in product recalls, are typically the most costly from the individual and/or societal perspective. Additional economic estimates of foodborne disease would contribute to our understanding of the burden of foodborne disease in Canada and would support the need for ongoing prevention and control activities.

Foodborne pathogens continue to cause several outbreaks every year in many parts of the world. Among the bacterial pathogens involved, Shiga toxin-producing Escherichia coli, Campylobacter jejuni, and nontyphoidal Salmonella species cause a significant number of human infections worldwide, resulting in a huge annual economic burden that amounts to millions of dollars in health care costs. Human infections are primarily caused by the consumption of contaminated food. Vaccination of food-producing animals is an attractive, cost-effective strategy to lower the levels of these pathogens that will ultimately result in a safer food supply and fewer human infections. However, producers are often reluctant to routinely vaccinate animals against these pathogens since they do not cause any detectable clinical symptoms.

Current food safety issues are deleteriously reshaping the life style of the population in the developing world. Socioeconomic status of the population in poorer economies is one of the major determinants to delineate the availability of safe food to the vulnerable population. Assessment of the prevalence of foodborne illness in developing world is the most neglected area to control disease. Botulism, Shigellosis, Campylobacteriosis, Escherichia coli infection, Staphylococcus aureus infection, Salmonellosis, Listeriosis and Cholerae are extensively prevalent and pose a major threat to human health in underdeveloped communities. The existing food safety status of many African, South Asian, Central, and South American developing countries is distressing therefore; it seems much timely to highlight the areas for the improvement to ensure the supply of safe food to the population in these regions. Extensive literature search at PubMed, Science Direct and Medline was carried out during the current year to catch on relevant data from 1976 to date, using selective terms like food safety, South East Asia, Africa, Central and South America, and foodborne illness etc. Efforts were made to restrict the search to low income countries of these regions with reference to specific foodborne pathogens. This report briefly discusses the present food safety situation in these developing countries and associated consequences as prime issues, suggesting foodborne illness to be the most distressing threat for human health and economic growth.

BACKGROUND: Governments require high-quality scientific evidence to prioritize resource allocation and the cost-of-illness (COI) methodology is one technique used to estimate the economic burden of a disease. However, variable cost inventories make it difficult to interpret and compare costs across multiple studies. METHODS: A scoping review was conducted to identify the component costs and the respective data sources used for estimating the cost of foodborne illnesses in a population. This review was accomplished by: (1) identifying the research question and relevant literature, (2) selecting the literature, (3) charting, collating, and summarizing the results. All pertinent data were extracted at the level of detail reported in a study, and the component cost and source data were subsequently grouped into themes. RESULTS: Eighty-four studies were identified that described the cost of foodborne illness in humans. Most studies (80%) were published in the last two decades (1992-2012) in North America and Europe. The 10 most frequently estimated costs were due to illnesses caused by bacterial foodborne pathogens, with non-typhoidal Salmonella spp. being the most commonly studied. Forty studies described both individual (direct and indirect) and societal level costs. The direct individual level component costs most often included were hospital services, physician personnel, and drug costs. The most commonly reported indirect individual level component cost was productivity losses due to sick leave from work. Prior estimates published in the literature were the most commonly used source of component cost data. Data sources were not provided or specifically linked to component costs in several studies. CONCLUSIONS: The results illustrated a highly variable depth and breadth of individual and societal level component costs, and a wide range of data sources being used. This scoping review can be used as evidence that there is a lack of standardization in cost inventories in the cost of foodborne illness literature, and to promote greater transparency and detail of data source reporting. By conforming to a more standardized cost inventory, and by reporting data sources in more detail, there will be an increase in cost of foodborne illness research that can be interpreted and compared in a meaningful way.

Objectives of this study were to determine the burden and impact of acute gastroenteritis (AGE) and foodborne pathogens in Trinidad and Tobago. A retrospective, cross-sectional population survey, based on self-reported cases of AGE, was conducted in November-December 2008 and May-June 2009 (high- and low-AGE season respectively) by face-to-face interviews. From 2,145 households selected to be interviewed, the response rate was 99.9%. Of those interviewed, 5.1% (n = 110; 95% CI 4.3-6.2) reported having AGE (3 or more loose watery stools in 24 hours) in the 28 days prior to the interview (0.67 episodes/person-year). Monthly prevalence of AGE was the highest among children aged < 5 years (1.3 episodes/year). Eighteen (16%) persons with AGE sought medical care (4 treated with oral rehydration salts and 6 with antibiotics), and 66% reported restricted activity [range 1-16 day(s)]. The mean duration of diarrhoea was 2.3 days (range 2-10 days). One case submitted a stool sample, and another was hospitalized. Overall, 56 (10%) AGE specimens tested positive for foodbome pathogens. It was estimated that 135,820 AGE cases occurred in 2009 (84% underreporting), and for every 1 AGE case reported, an additional 6.17 cases occurred in the community. The estimated economic cost of AGE ranged from US$ 27,331 to 19,736,344. Acute gastroenteritis, thus, poses a huge health and economic burden on Trinidad and Tobago.

Acute gastroenteritis (AGE) is an important public-health issue in Dominica. To determine the burden of AGE in Dominica, a retrospective, cross-sectional population survey was conducted in March-April 2009 and October 2010 (low- and-high-AGE seasons) and a laboratory survey from April 2009 to March 2010. The overall monthly prevalence of self-reported AGE was 8.6 % (95% CI 7.0-10.6); the incidence rate was 1.1 episodes/person-year and 79,157.1 episodes of AGE for the total population/year. Monthly prevalence of AGE was the highest in the 1-4 year(s) age-group (25.0%), higher in females (10.8%) and also varied by health district, with the highest monthly prevalence of AGE being reported in the Portsmouth district (13.1%). This difference in gender and across the health region was statistically significant. The estimated underreporting of syndromic AGE to the Ministry of Health was 83.3%. Furthermore, for every reported laboratory-confirmed case of AGE and foodbome disease (FBD), there was an estimated underreporting factor of 280. Overall, 47% of AGE specimens tested were positive for FBD pathogens. The predominant pathogens isolated were norovirus, followed by Giardia, Salmonella, and Shigella. The total annual estimated cost of AGE was US$ 1,371,852.92, and the total cost per capita due to AGE was US$ 19.06, indicating an economic burden of AGE-related illness on a small island of Dominica.

Guyana is an English-speaking country in South America and, culturally, it is part of the Caribbean. Objective of this study was to determine the community prevalence and true burden and economic impact of acute gastroenteritis (AGE) and foodborne diseases (FBDs) in Guyana. A cross-sectional population-based survey was conducted in 7 of the 10 regions in Guyana during August and November 2009 to capture the high- and low-AGE season respectively. Overall, 1,254 individual surveys were administered at a response rate of 96.5%. The overall monthly prevalence of self-reported cases of AGE was 7.7% (97 cases) (95% CI 6.3-9.3), and the yearly incidence was 1.0 episodes per person-year. The highest monthly prevalence of AGE was observed in region 4 (8.9%) and in children aged 1-4 year(s) (12.7%). Of the 97 AGE cases, 23% sought medical care; 65% reported spending time at home due to their illness [range 1-20 day(s), mean 2.7 days], of whom 51% required other individuals to look after them while ill. The maximum number of stools per 24 hours ranged from 3 to 9 (mean 4.5), and number of days an individual suffered from AGE ranged from 1 to 21 day(s) (mean 2.7 days). The burden of syndromic AGE cases in the population for 2009 was estimated to be 131,012 cases compared to the reported 30,468 cases (76.7% underreporting), which implies that, for every syndromic case of AGE reported, there were additional 4.3 cases occurring in the community. For every laboratory-confirmed case of FBD/AGE pathogen reported, it was estimated that approximately 2,881 more cases were occurring in the population. Giardia was the most common foodborne pathogen isolated. The minimum estimated annual cost associated with the treatment for AGE was US$ 2,358,233.2, showing that AGE and FBD pose a huge economic burden on Guyana. Underreporting of AGE and foodbome pathogens, stool collection, and laboratory capacity were major gaps, affecting the surveillance of AGE in Guyana.
