Due to the increasing number of cases and the absence of an estimate of the number of COVID-19 cases in Quebec, a study is in progress at CIRANO to assess the incidence of COVID-19 in the province.
Using a weekly survey on 3000 Quebecers, administered over a 4-week period, and using a sampling approach based on the network scale up method, a team of researcherscomposed of David Boisclair (HEC Montréal), Roxane Borgès Da Silva (Université de Montréal and CIRANO), Vincent Boucher (Université Laval) Nathalie de Marcellis-Warin (Polytechnique Montréal and CIRANO), Pierre-Carl Michaud (HEC and CIRANO) and Ingrid Peignier (CIRANO), is working to estimate the incidence of COVID-19, i.e. the number of adults having received a positive test, either rapid or PCR, or having self-diagnosed themselves as having COVID-19 based on symptoms.
The first results were released on Friday, January 21, 2022 for the seven-day period ending January 13-18, 2022. See the results
Supplements will be published every week with an update of the data since the survey will be repeated over 4 consecutive weeks in order to follow the evolution.
