One of the key ways that the experts are gauging how well a country has on its pandemic is the percentage of positive tests.

Another useful way is random testing for antibodies in a general population.

Using sero-prevalence research (looking for antibodies in the blood samples of a random group of people), it estimates fewer than one per cent of British Columbians were infected with coronavirus by the time first wave restrictions were eased in May.

It means around eight times more B.C. residents have been infected than the number of cases reported, the study authors estimate. Fewer than one in 100 people in the Lower Mainland became infected with COVID-19, suggesting an even lower infection rate for other parts of the province.

Skowronski said she believed the results were likely to be more accurate because the blood samples were random and not based on volunteers. Research dependent on voluntary donors tends to skew toward higher infection rates as those people often have reason to be worried they have the virus.
