To estimate the global burden of nontyphoidal Salmonella gastroenteritis, we synthesized existing data from laboratory-based surveillance and special studies, with a hierarchical preference to (1) prospective population-based (2) "multiplier studies," (3) disease notifications, (4) returning traveler data, (5) extrapolation. We applied incidence estimates population projections for 21 Global Burden Disease regions calculate regional numbers cases, which were summed provide number cases....
Background Evidence-based priority setting is increasingly important for rationally distributing scarce health resources and guiding future research. We sought to quantify the contribution of a wide range infectious diseases overall disease burden in high-income setting. Methodology/Principal Findings used health-adjusted life years (HALYs), composite measure comprising premature mortality reduced functioning due disease, estimate 51 associated syndromes Ontario using 2005–2007 data. Deaths...
Abstract Background This article reports the results of a rapid scoping review literature on COVID‐19 transmission risk to workers in essential sectors such as retail, health care, manufacturing, and agriculture, more particularly experiences precarious employment social situations. Methods Following methods, we included 30 studies that varied terms methodology theoretical approaches. The search peer‐reviewed articles grey published between March September 2020. Results Based reviewed, found...
Background Studies in several countries have estimated the prevalence of diarrhoea community. However, use different study designs and varying case definitions has made international comparisons difficult.
Abstract Background In Canada, the legal responsibility for condition of private water supplies, including wells and cisterns, rests with their owners. However, there are reports that Canadians test these supplies intermittently treatment such is uncommon. An estimated 45% all waterborne outbreaks in Canada involve non-municipal systems. understanding perceptions needs served by essential, as it would enable public health professionals to better target education drinking policy. The purpose...
ABSTRACT This paper explores the ways in which consumers assess safety of food restaurants and other eating‐out establishments, resulting impact on restaurant choice. The analysis builds existing literature choice more generally a growing body studies official inspection information perceived restaurants. Based two‐stage consumer study City Hamilton Ontario, Canada, involving focus groups postal survey, research highlights how base their assessment using range visible indicators experience...
National studies determining the burden of gastroenteritis have defined by its clinical picture, using symptoms to classify cases and non-cases. The use different case definitions has complicated inter-country comparisons. We selected four from literature, applied these population data Australia, Canada, Ireland, Malta United States, evaluated how epidemiology illness varied. Based on results, we developed a standard definition. choice definition impacted observed incidence gastroenteritis,...
Abstract Shiga toxin-producing Escherichia coli (STEC) infections pose a substantial health and economic burden worldwide. To target interventions to prevent foodborne infections, it is important determine the types of foods leading illness. Our objective was food sources STEC globally for six World Health Organization regions. We used data from outbreaks that have occurred estimate source attribution fractions. categorised according their ingredients applied probabilistic model information...
Abstract Background: Antimicrobial resistance (AMR) causes worsening health, environmental, and financial burdens. Modelling complex issues such as AMR is important, however, how well models data cover the broader One Health system unknown. Our study aimed to identify of across (objective 1), parameterize 2) inform a future model in Swedish system. Based on an expert-derived qualitative description system, extensive literature scan was performed from peer-reviewed grey sources. Models were...
To estimate the magnitude and distribution of self-reported, acute gastrointestinal illness in a Canadian-based population, we conducted retrospective, cross-sectional telephone survey approximately 3500 randomly selected residents city Hamilton (Ontario, Canada) from February 2001 to 2002. The observed monthly prevalence was 10% (95 % CI 9.94-10.14) incidence rate 1.3 1.1-1.4) episodes per person-year; this is within range estimates other developed countries. higher females those aged < 10...
To estimate the annual number of cases illness due to verotoxigenic Escherichia coli (VTEC), Salmonella and Campylobacter in Canadian population, using data from National Notifiable Disease registry (NND), estimates under-reporting derived several Studies on Acute Gastrointestinal Illness, literature.
Salmonella enteritidis has emerged as the most prevalent cause of human salmonellosis in Canada. Recent trends S. subtypes and their potential sources were described by integrating data from several Canadian surveillance monitoring programmes. A threefold increase cases 2003 to 2009 was identified be primarily associated with phage types 13, 8 13a. Other common (4, 1, 6a) showed winter seasonality more likely linked international travel. Conversely, 13a had summer seasonal peaks domestically...
Foodborne diseases are an important public health issue, and young adults demographic to target with food safety education. Our objective was assess the knowledge of undergraduate students at a Canadian university, identify potential areas for such In February 2015, we conducted online survey 485 university in Ontario, Canada. We assessed various food-related factors, including cooking frequency prior handling or preparation then modeled relationship between 'overall score' skills/cooking...
Abstract The global threat of antimicrobial resistance (AMR) requires coordinated actions by and across different sectors. Increasing attention at the national levels has led to strategies tackle challenge. diversity possible address AMR is currently not well understood from a One Health perspective. AMR-Intervene, an interdisciplinary social–ecological framework, describes interventions in terms six components: (i) core information about publication; (ii) social system; (iii) bio-ecological...
Introduction Antimicrobial resistance (AMR) is a global crisis that evolves from complex system of factors. Understanding what factors interact key to finding solutions. Our objective was identify the influencing AMR in European food and places intervene. Materials methods We conducted two workshops involving participants with diverse perspectives leverage points (places) target interventions. Transcripts were open coded for connections, then transcribed into Vensim 8.0.4 develop causal loop...
In developed countries, gastrointestinal illness (GI) is typically mild and self-limiting, however, it has considerable economic impact due to high morbidity. The magnitude distribution of acute GI in British Columbia (BC), Canada was evaluated via a cross-sectional telephone survey 4,612 randomly selected residents, conducted from June 2002 2003. Respondents were asked if they had experienced vomiting or diarrhoea the 28 days prior interview. A response rate 44.3% achieved. monthly...
