There are currently over 80 species of mosquito endemic in Canada-although only a few these carry pathogens that can cause disease humans. West Nile virus, Eastern equine encephalitis virus and the California serogroup viruses (including Jamestown Canyon snowshoe hare viruses) mosquito-borne have been found to human infections North America, including Canada. Over last 20 years, incidence most diseases (MBD) has increased approximately 10% Canada, due large part climate change. It is...
Gastrointestinal illnesses (GI) continue to pose a substantial burden in terms of morbidity and economic impact Canada. We describe the epidemiology reportable GI Ontario by characterizing incidence each GI, as well associated demographics, clinical outcomes, seasonality, risk settings, likely sources infection.Reports on laboratory confirmed cases amebiasis, botulism, campylobacteriosis, cryptosporidiosis, cyclosporiasis, giardiasis, hepatitis A, listeriosis, paratyphoid fever,...
OBJECTIVE: Antibiotic resistance is accelerated by the overuse of antibiotics. Do Bugs Need Drugs? an educational program adapted in British Columbia to target both public and health care professionals, with aim reducing unnecessary prescribing. The current article presents a descriptive evaluation impact over first four years. METHOD: Program implementation was measured amount material distributed level participation sessions. assessed measuring changes knowledge prescribing habits...
SUMMARY In Ontario, Canada, the number of Salmonella Enteritidis (SE) cases increased over years 2005–2010. A population-based case-control study was undertaken from January to August 2011 for purpose identifying risk factors acquiring illness due SE within Ontario. total 199 and 241 controls were enrolled. After adjustment confounders, consuming any poultry meat [adjusted odds ratio (aOR) 2·24, 95% confidence interval (CI) 1·31–3·83], processed chicken (aOR 3·32, CI 1·26–8·76) not washing...
Lyme disease, the most commonly reported vector-borne disease in North America, is caused by spirochete Borrelia burgdorferi sensu stricto, which transmitted Ixodes scapularis eastern Canada and pacificus western Canada. Recently, northward range expansion of I. ticks, south-eastern Canada, has resulted a dramatic increase incidence human disease. Detecting emerging areas risk allows public health to target prevention efforts. We analysed passive tick surveillance data from Ontario Manitoba...
Abstract Background Increases in the number of salmonellosis cases due to Salmonella Enteritidis (SE) 2010 and 2011 prompted a public health investigation Ontario, Canada. In this report, we describe current epidemiology travel-related (TR) SE, compare demographics, symptoms phage types (PTs) TR domestically-acquired (DA) cases, estimate odds acquiring SE by region world visited. Methods All incident culture confirmed Ontario obtained from isolates specimens submitted laboratories were...
Contact with animals and their environment has long been recognized as an important source of enteric zoonoses. However, there are limited data available on the burden illness associated specific types in Canada. This study describes overall zoonoses Ontario, Canada from 2010 to 2012. Confirmed cases seven zoonotic diseases (campylobacteriosis, cryptosporidiosis, giardiasis, listeriosis, salmonellosis, verotoxin-producing E. coli (VTEC) infection, yersiniosis) episode dates 2012 were...
Summary In December 2012, an increase in human Salmonella Typhimurium cases was identified the province of Ontario, Canada launching outbreak investigation. The spanned 3 years (2012–2014), with 134 reported from five Canadian provinces. There a substantial burden illness among children: 45% were children 12 old or under, and 23% under 5 old. Epidemiologic, traceback laboratory findings linked this to feeder rodents (used feed snakes) supplied by network rodent breeders Ontario. Cases likely...
Salmonella Reading (S. Reading) is a rare serotype of subspecies (spp.) in Canada with less than nine cases reported each year (2011-2013). An increase S. was identified several Canadian provinces early 2015, prompting the initiation national outbreak investigation.To describe multi-provincial that affected over 30 people.Cases were defined as laboratory-confirmed related pulsed-field gel electrophoresis (PFGE) patterns. Onset dates between November 2014 and September 2015.: Early...
Low socioeconomic status has been associated with increased morbidity and mortality for various health conditions. The purpose of this study was twofold: to examine the experience older persons admitted hospital community acquired pneumonia test hypothesis whether an association exists between subsequent admission community-acquired pneumonia.A population based retrospective cohort conducted including all patients Ontario hospitals April 1995 March 2001. main outcome measures were 30 day 1...
National West Nile virus (WNV) surveillance was established in partnership with the federal, provincial and territorial governments starting 2000, aim to monitor emergence subsequent spread of WNV disease Canada. As emerged, national continued focus on early detection outbreaks different parts country. In Canada, transmission season occurs from May November. During season, system adopts a One Health approach collect, integrate, analyze disseminate data human, mosquito, bird other animal...
Background Aedes japonicus was first documented in Ontario, Canada, 2001. The objective of this study to determine the effect Ae. establishment on abundance other mosquitoes Greater Golden Horseshoe (GGH) region Ontario. Methods Adult mosquito data from Ontario West Nile virus surveillance program were used. Descriptive analyses, linear trends and distribution maps average trap count per month for six species interest produced. Multivariable negative binomial regression models constructed 1)...
The objective of this study was to assess the use statistical algorithms in identifying significant clusters Salmonella spp. across different sectors food chain within an integrated surveillance programme. Three years weekly serotype data from farm animals, meat, and humans were used create baseline models (first two years) identify weeks with counts higher than expected using third (test) year. During test year, expert working group identified events interest reviewing descriptive analyses...
Jamestown Canyon virus (JCV) is a mosquitoborne orthobunyavirus in the California serogroup that circulates throughout Canada and United States. Most JCV exposures result asymptomatic infection or mild febrile illness, but can also cause neurologic diseases, such as meningitis encephalitis. We describe case series of confirmed JCV-mediated neuroinvasive disease among persons from provinces British Columbia, Alberta, Quebec, Nova Scotia, Canada, during 2011-2016. highlight definitions,...
The COVID-19 pandemic highlighted the need for timely, evidence-based rapid risk assessments (RRA) of infectious disease events to inform public health action during rapidly evolving situations with high uncertainty. In 2022, Public Health Agency Canada established a coordinated approach assessment, including methodology qualitative RRA threats.
