BARRIE, ONT. -- Simcoe Muskoka's health unit reports the number of COVID-19 variant cases has nearly doubled Wednesday, increasing to 90 diagnoses, with an additional 57 possible cases. Health officials noted the variant requires two tests to detect - those 57 people have so far screened positive and are waiting on results from a second test to confirm. The new coronavirus strain has been identified at a Barrie, Ont., long-term care home devastated by an outbreak that has claimed 66 lives. More than 230 residents and staff at Roberta Place have been diagnosed since the outbreak was declared on Jan. 8. On Tuesday, the Waypoint Centre for Mental Health Care in Penetanguishene, Ont., said that one individual "was positive for a particular mutation indicating a high probability that this individual has a variant strain of concern of COVID-19."
