coronavirus transmission between kids in schools, Ottawa’s medical officer of health said Tuesday.Dr. Vera Etches told reporters during a media availability Tuesday afternoon that she has heard people dismissing the importance of social circles and limiting contact with others as children prepare to go back to school in the fall.Many parents have questioned the Ontario government’s call to send younger kids back to school without reducing class sizes to better allow for physical distancing, worrying the decision could make classrooms into hotspots for the virus.But Ottawa’s top doctor pushed back against the assertion that kids’ return to school after five months outside the classroom will defeat the purpose of limiting close contact.
