TORONTO -- Ontario health officials have confirmed two more COVID-19-related deaths in the province, as 85 new cases of the novel coronavirus were announced on Tuesday morning.

The first deceased patient, a woman in her 90s, was a resident of Hillsdale Terraces, a long-term care home in Oshawa, Ont.

She died on Monday after she was transferred from the facility to Lakeridge Health Oshawa for medical treatment, the Durham Region Health Department (DRHP) confirmed in a news release issued on Tuesday.

This was the first COVID-19-related death in the region.

“It is truly unfortunate that this woman’s tragic passing underscores the need for us to work together as a community to help stop the spread of COVID-19,” Durham Region Medical Officer of Health Dr. Robert Kyle said in the news release.

“We need everyone’s help to protect those most vulnerable in our community and encourage all area residents to take the practice of social and physical distancing very seriously and take actions to protect yourself and others in our community.”

A spokesperson for DRHP said 20 residents of Hillsdale Terraces are currently in self-isolation due to COVID-19.

The second deceased patient was an 80-year-old woman who died at St. Joseph's Hospital in Hamilton, Ont. Ontario public health said that the woman had been in isolation since being admitted to the hospital on March 16. She was a resident of Heritage Green Nursing Home in Stoney Creek.

The provincial total of confirmed cases of the virus now sits at 588.

This time last week, Ontario had 180 confirmed cases – that is an increase of about 217 per cent over the past seven days.

The new patients announced on Tuesday morning include two other cases in Durham Region, as well as 17 in Toronto, five in York Region, three in Peel Region, three in Hamilton, and one in Halton Region.

Two of the new patients remain in hospital receiving medical treatment. The other cases are either in self-isolation at home or their location is listed as “pending.”

As the new patients were confirmed on Tuesday, provincial health officials stated that there are more than 10,000 people currently under investigation for the virus, while more than 20,000 people in Ontario have tested negative.

Speaking at a news conference on Tuesday, Ontario's Associate Medical Officer of Health Dr. Barbara Yaffe said that since the first case was confirmed in the province on Jan. 25, 50 people have been hospitalized, 17 of which required the intensive care unit.

Six other COVID-19 patients have died in Ontario. They are a 77-year-old Barrie, Ont. man, a 51-year-old Milton, Ont. man, a 77-year-old Toronto man, a woman in her 70s in York Region, a man in his 70s in Barrie, Ont., and a man in his 80s in Lindsay, Ont.

In the province, eight people previously infected with the virus have since recovered.

Symptoms of the virus, which can include fever, cough and shortness of breath, are similar to other respiratory infections.

There are no specific treatments for the virus and there is no vaccine that protects against it.
