Study found eight times more infections than tests, but rate of community transmission less than one per cent
A pedestrian walks past artwork of women wearing face masks painted on a wall as a man plays a game on two phones, in Vancouver, on Sunday, July 12, 2020.A recent study in British Columbia confirms far more people have carried the novel coronavirus than were tested for it, and public health officials say the findings will help tailor future strategies to control the illness.
Henry says given the scant level of community transmission, what is now needed is targeted testing to determine who has been most affected by the respiratory illness. She says when an outbreak occurred in Alert Bay off northern Vancouver Island in late April, serology tests were done on “a good proportion” of residents there.“That gives us a better idea of how this virus is transmitted in community settings so we can more nimbly target outbreaks as we go into the fall,” she says.
