TORONTO -- Slightly more than one per cent of Ontarians – roughly 160,000 people – were infected and had recovered from the novel coronavirus by the end of June, Public Health Ontario says after conducting tests on thousands of blood samples.
The agency said that of more than 7,000 blood samples tested during the month of June, 79 showed the presence of COVID-19 antibodies, indicating a prevalence of 1.1 per cent when adjusted to the characteristics of Ontario's population.
The lab found a higher prevalence of antibodies among those aged 80 and over (2.6 per cent) and no presence of antibodies in children under the age of nine.
