Quebec added 155 new COVID-19 cases today, bringing the total number of people infected to 60,000.
The province also added two deaths, for a total of 5,687 since the beginning of the pandemic.
The Health Department reports two fewer patients in hospital for 167, with 19 of those in intensive care, also a reduction of two.
The latest figures come as the results of an antibody study by Quebec’s blood collection agency has concluded that about 2.23 per cent of the province’s adult blood donors had contracted COVID-19.
The seroprevalence study by Hema-Quebec and the province’s public health institute tested the blood of 7,691 people between the ages of 18 and 69 who donated blood between May 25 and July 9.
When extrapolated to the rest of the population, the study estimated that some 124,800 adults contracted the virus since the pandemic began.
The Quebec government reported some 37,000 cases for the 20 to 69 age group in the same period.
The study revealed that the highest rates of infection were found in Montreal and Laval, with just over three per cent, while in most of the rest of the province the rate was much lower at 1.29 per cent.
Authorities will contact the donors who had COVID-19 antibodies to document their symptoms in order to estimate how many of them were asymptomatic.
