MONTREAL — There's no epidemiological link between six cases of COVID-19 among emergency room employees at a local hospital, the regional health authority in Laval, Que., said Saturday. Marie-Eve Despatie-Gagnon, a spokeswoman for the health authority, said three doctors and three other employees who work in the emergency room at the Cite-de-la-Sante Hospital have tested positive for the novel coronavirus. There is no outbreak in the hospital's emergency room, Despatie-Gagnon said, adding that no emergency room patients got the virus from any of the workers. The health authority said that community transmission is to blame for some of the cases, and it maintains that there is no link between any of the six.
