TORONTO -- The total number of COVID-19 patients in Ontario has risen to 688, as health officials confirmed 100 more cases of the novel coronavirus on Wednesday, including five more deaths in the province.

The first of the five deaths announced Wednesday was an individual in their 80s who was a resident at Ina Grafton Gage Village, a retirement home in St. Catharines.

The individual was receiving care at a hospital in Niagara.

“On behalf of the hospital, I would like to extend our sincere condolences to the patient’s family and loved ones at this extremely sad time,” a spokesperson for Niagara Health said in a news release issued on Wednesday.

“We all mourn this loss as a community.”

Speaking to reporters on Wednesday afternoon, Ontario's associate chief medical officer of health said the patient died 11 days after he was confirmed to have the virus.

"This person had close contact with a family member who recently travelled to Europe," Dr. Barbara Yaffe said.

No information has been released by provincial health officials about the four other deceased patients.

On Wednesday afternoon, Toronto public health officials confirmed three new COVID-19-related deaths in the city, but it is unclear if those numbers are included in the provincial total.

As the 100 new patients were confirmed, officials stated that more than 10,000 people are currently under investigation for the virus and more than 24,000 people in the province have tested negative thus far.

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.
