A study to assess the prevalence of COVID-19 in Quebec is in progress at CIRANO

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 prevalence 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 researchers, under the direction of Pierre-Carl Michaud (HEC Montréal and Main Researcher of the Demography and Health theme at CIRANO), is working to estimate the prevalence of COVID-19, i.e. the frequency of persons having received a positive test, either rapid or PCR, or having self-diagnosed themselves as having COVID-19 based on symptoms. First results will be available during the week of January 17.
