A study of recent blood donors suggests three times as many Quebecers could have been infected with the novel coronavirus than is reflected in the official numbers.
The study, conducted by Héma-Québec in collaboration with the Institut national de santé publique, confirmed that 2.23 per cent of 7,691 people who donated blood between May 25 and July 9 had contracted COVID-19.
Based on the sample data, the study extrapolates that 124,880 Quebecers aged 18 to 69 had been infected between the start of the pandemic and early July. In the same time period, the study notes that Quebec's Health Ministry had recorded fewer than 40,000 Quebecers ages 20 to 69 as confirmed cases.
As of Tuesday, there are 59,845 confirmed cases, of all ages, in the province.
