Top Ontario health official says coronavirus surveillance is widening
TORONTO — Monitoring for the novel coronavirus in Canada will now shift into a new phase, focusing on people returning from areas of China that haven’t been quarantined, top provincial and federal medical officials said Thursday.
It has now been 14 days — the maximum incubation period for the virus — since some cities in China were essentially locked down, including the city of Wuhan where the outbreak originated. Anyone who returned from those regions before that time would have likely already shown symptoms if they were infected.
But Dr. David Williams, Ontario’s Chief Medical Officer of Health, said officials can’t be complacent. Even with the incubation period ending for anyone who would have come to Canada from the now-quarantined cities, more people in Ontario are still being tested each day for the virus, Williams said.
More and more, doctors are asking for patients to be tested who don’t strictly meet the case definition of symptoms plus recent travel to the affected area, he said. People who have been to areas near the quarantined cities may still have been in contact with an infected person, Williams said.
