Transition to Whole Genome Sequencing Surveillance: The Impact on National Outbreak Detection and Response for , , Shiga Toxin-Producing , and Clusters in Canada, 2015-2021.

Between 2017 and 2019, pulsed-field gel electrophoresis was replaced by whole genome sequencing (WGS) for identifying enteric disease clusters in Canada. The number and characteristics of all clusters of , , Shiga toxin-producing (STEC), and spp. between 2015 and 2021 were analyzed.

Investigation of acute severe hepatitis in children: A review of liver transplant data, Canada, 2021-2022.

An increase in severe acute hepatitis of unknown etiology was first reported in the United Kingdom in April 2022. Following this report, the Public Health Agency of Canada connected with three paediatric liver transplant centres across Canada to determine if an increase in liver transplants was noted. Data demonstrated no observable increase in the number of transplants conducted in 2022.

Acute severe hepatitis of unknown origin in children in Canada.

Background: In spring 2022, a series of reports from the United Kingdom and the United States identified an increase in the incidence of acute severe hepatitis in children. The Public Health Agency of Canada (PHAC) collaborated with provincial/territorial health partners to investigate in Canada. Clinical hepatitis, or inflammation of the liver, is not reportable in Canada, so to determine if an increase was occurring above historical levels, the baseline incidence in Canada was estimated.

Direct oral anticoagulant (DOAC) monitoring within primary care: a quality improvement project.

Background: Poor monitoring of anticoagulants is a significant area of patient safety. It can lead to the dichotomous risk of haemorrhage/clotting without appropriate counselling and monitoring. While healthcare professionals may be familiar with the anticoagulant warfarin and the international normalised ratio, they might be unaware of the monitoring requirements of direct oral anticoagulants (DOACs), despite DOACs making up 62% of anticoagulants prescribed.

Impact of the COVID-19 Pandemic on the Reported Incidence of Select Bacterial Enteric Diseases in Canada, 2020.

The aim of this study was to describe the impact of the COVID-19 pandemic on reported cases and clusters of select enteric diseases in Canada, for the period of March 2020 to December 2020. Weekly counts of laboratory confirmed cases of , , Shiga toxin-producing (STEC), and were obtained from laboratory surveillance data. These data were supplemented with epidemiological information on the suspected source of illness, collected for cases identified within whole genome sequencing clusters.

Consumption of High-Risk Foods in the Canadian Population, Foodbook Study, 2014 to 2015.

Abstract: Many foods have the potential to cause foodborne illness; however, some pose a higher risk. Data were collected through the Foodbook study, a population-based telephone survey conducted between 2014 and 2015 that assessed 10,942 Canadians' food exposures using a 7-day recall period. The 19 foods included in the survey were identified as high risk for common foodborne pathogens in Canada.

Country food consumption in Yukon, Northwest Territories and Nunavut, Foodbook study 2014-2015.

Background: This article presents a descriptive summary of the consumption of various country food (i.e. locally harvested plant and animal foods) products by residents of Yukon (YT), Northwest Territories (NT) and Nunavut (NU).

Detection of noroviruses in ready-to-eat foods by using carbohydrate-coated magnetic beads.

This study used histo-blood group antigen-conjugated beads to detect norovirus (NoV) in contaminated strawberries, green onions, lettuce, and deli ham. In addition, multiple strains of NoV from genogroups I and II were recovered. This provides an effective protocol for food testing in the investigation of suspected NoV outbreaks.
