Chief Medical Officer of Health Dr. Deena Hinshaw said Wednesday that testing for COVID-19 in flu samples from the surveillance network had started in March, but that the samples had not been tested before.
Hinshaw said the province is investigating the possibility of serological testing, once validated, and of sampling Albertans who may not have received confirmation of COVID-19 through a swab, but who may have been infected in the past and were not aware of it.
“These studies are reviewed and subject to ethical approval to ensure that we formulate them appropriately and that we consider who we would offer these tests for,” she said.
“It can help us to know whether or not people were infected before the first case we knew of.”
