The Ministry of Health has announced an additional 85 newly-confirmed cases of COVID-19 infection in Ontario Tuesday bringing the total of confirmed active cases in the province to 573. Details of the latest ministry report may be seen at the government website. Perhaps the most worrisome number is that for cases under investigation, which has leaped to 10,074. Tuesday’s confirmed cases (85) exceed a previous high of 78 reported on Monday. As the daily load of cases creeps upward health officials and the public will watch for evidence that this number might explode as seen in some European jurisdictions. Or, is the firm quarantine and shutdown strategy at least controlling the spread of the infection?
