加拿大统计局收集血液样本

Statistics Canada is mailing pinprick blood tests to forty eight thousand Canadians to gauge the virus’ prevalence in the country. In what is one of the first large-scale surveys of its kind in Canada, researchers are examining the blood samples for antibodies pertaining to the virus that causes COVID-19. Each participant will first be asked to fill out an online questionnaire. Upon giving consent, a testing kit will be mailed to that person’s address. The sampling tests sent randomly to Canadians include gloves, a needle, alcohol swabs and sealable package. The participants will be asked to prick their finger and make a print on each of five markings on a dried blood card.
