Three sequential outbreaks of Group A over a two-year period at the Canadian Forces Leadership and Recruit School, St. Jean Garrison, Québec.

Background: Since December 2016, the basic military training (BMT) facility for the Canadian Armed Forces (CAF) has experienced repeated outbreaks of Group A (GAS). In 2018, a voluntary mass antibiotic prophylaxis (MAP) program was implemented to interrupt GAS transmission among recruits. The objective of this study was to describe the epidemiology of three GAS outbreaks and a period of increased pharyngitis infections at the CAF BMT facility in Québec over a two-year span, and to detail the prevention and control measures implemented to mitigate the risk to recruit health.

Adverse events following mass antibiotic prophylaxis during a Group A outbreak in the Canadian Forces Leadership and Recruit School.

Background: Between December 2016 and March 2018, two outbreaks of Group A (GAS) infection occurred at the Canadian Forces Leadership and Recruit School. A voluntary mass antibiotic prophylaxis (MAP) program was implemented in March 2018, to interrupt an ongoing GAS outbreak, and to prevent future outbreaks.

Methods: Instructors and recruits were offered a one-time intramuscular injection of 1.

Group A Streptococcus Outbreak in a Canadian Armed Forces Training Facility.

Between December 2016 and April 2017, two cases of invasive Group A Streptococcus (GAS) infections were reported at a Canadian military training facility. An outbreak was declared and a field investigation was launched to characterize the outbreak and identify associated risk factors to limit transmission. Throat culture data from military personnel at the garrison were analyzed.

Good interventions that few use: uptake of insect bite precautions in a group of Canadian Forces personnel deployed to Kabul, Afghanistan.

We evaluated use of interventions to prevent insect bites in Canadian personnel deployed to Kabul, Afghanistan. Data were collected through a self-report written survey. The response rate was 92%, and intervention uptake was 11% applied repellent that day, 21% slept under a bednet their last sleep, and 78% wore insecticide-treated clothing.

Pandemic (H1N1) 2009 outbreak at Canadian Forces cadet camp.

We conducted a case-control study to describe the clinical and epidemiologic characteristics of an outbreak of pandemic (H1N1) 2009 at a Canadian military cadet training center. We found that asthma and obesity confer greater risk for infection. Viral shedding was detected by PCR up to 18 days after symptom onset.

Malaria risk assessment and preventive recommendations: a new approach for the Canadian military.

Western militaries deploying to international locations are often confronted with the threat of malaria. For the Canadian military, the consequent response has been prescriptive-any risk of malaria warrants use of personal protective measures and chemoprophylaxis. In reality, however, malaria risk is highly variable and a one-size-fits-all strategy to mitigation may not be appropriate.

Laboratory and field evaluation of the impact of exercise on the performance of regular and polymer-based deet repellents.

Studies were done in Manitoba, Canada, to evaluate the impact of exercise on repellent performance against mosquitoes. Two products containing the active ingredient N,N-diethyl-3-methylbenzamide (deet) were tested; one product was a polymer-based cream (3M Ultrathon Insect Repellent) and the other product was an alcohol-based pump spray formulation (Muskol Insect Repellent). Assessments were done in the laboratory using Aedes aegypti (L.

Field evaluation against mosquitoes of regular and polymer-based deet formulations in Manitoba, Canada, with comment on methodological issues.

Studies were carried out in Manitoba, Canada, to evaluate the efficacy of three repellent products for protection of human subjects against mosquito bites. All test substances contained the active ingredient N,N-diethyl-3-methylbenzamide (deet); two were polymer-based creams (3M Ultrathon Insect Repellent and Morflex DEET Insect Repellent 30) and the third (Muskol Insect Repellent) was an alcohol-based pump spray formulation. Application of repellent was to the forearm and lower legs of subjects at 0.

An epidemiologic study of hepatocellular carcinoma in Canada.

Background And Methods: To provide information on poorly described Canadian hepatocellular cancer epidemiology, we analyzed incident cases abstracted from the Canadian Cancer Registration Database (1969-1997) and Canadian annual death data (1969-1998). Age, sex, geographic distribution, and secular trends were described. Projection models were developed for the next decade.
