A study locally here in Vancouver, British Columbia suggests that 8 times more people have actually been infected than the officially confirmed case numbers suggest. The study was done by testing samples from the Red Cross blood bank, so it has the value of being a fairly randomized sample.
Study suggests 8 times more people in B.C. infected with virus than confirmed
