MONTREAL – The results from the analysis of the first 10,000 samples of blood to detect for the presence of antibodies against the SARS-CoV-2, disease, coronavirus, indicate that little of canadian adults have contracted the virus.
In fact, less than 1 % of these 10 000 samples collected from 9 may to 8 June, in nine canadian provinces, had antibodies to the new coronavirus, according to a study conducted by the canadian blood services and the working Group on immunity in the face of the COVID-19 in Canada, put in place last April.
The data do not include those of Héma-Québec, which manages the procurement, management and distribution of blood in the Belle Province.
The results will be updated when the analysis of the 37 800 blood samples taken in may and June will be completed, told, Thursday, by press release. They will allow us to better understand the rate of infection to the COVID-19 to guide the intervention of the public health and to dictate political choices, believe the canadian blood services and the working Group on immunity in the face of the COVID-19.
“What is clear is that only a small percentage of adult canadians were infected with SARS-CoV-2”, said dr. Catherine Hankins, co-chair of the working Group on immunity in the face of the COVID-19.
However, it would be dangerous at this stage to lower its guard, the virus always trying to spread. “We are still very much vulnerable to infection, she added. It is necessary to accelerate the screening and searching of contacts across the country to break fast in the chains of transmission and prevent the spread of control.”
If the preliminary data suggests that few Canadians have been contaminated by the COVID-19, they could also suggest that many infections have simply not been identified, because of the asymptomatic persons and others who have had mild symptoms that were not encouraged to move to the testing centre nearest to you.
“These data suggest that there are many cases of infection not detected for each case confirmed by means of a levy or of a test based on RNA,” said his side the professor David Naylor, co-chair of the Group.
“This demonstrates the merits of the directives of public health: wear a mask in indoor public places, wash hands often and observe physical separation with people who are not part of our “social circle” COVID-19″, he continued.
