Ontario's chief medical officer of health announced three more positive cases of COVID-19 on Saturday, bringing the total number of cases to 11.



This comes a day after Dr. David Williams had announced its seventh and eighth cases, and all three new ones are in the GTA.



The first of the three new cases is a 34-year-old woman who came to MacKenzie Health in York Region with mild symptoms on Thursday, after returning to Toronto the day before from Iran.

York Region Medical Officer of Health Dr. Karim Kurji explained they are also reaching out to people who were in proximity to the woman, who was on three flights and one GO bus.

The flights include the business class section of Qatar Airways flight QR 483 and QR 163, Air Canada flight AC 883, while the GO bus was the #40 EB sitting on the upper deck.

She got on the bus on Wednesday, February 26 at approximately 3:55 p.m., from Pearson Airport to the Richmond Hill Centre Terminal.

"Eventually we will be getting the flight manifest," he said, adding however in these cases, "the individauls that we find usually do not develop symptoms."

As for the GO bus, there is much less risk, he said.

"There is more ventiliation, the period of travel is much less in time and there may be individuals who were boarding and unboarding the bus," he said. "We would like though these individuals to get in touch with us."

Passengers should contact 1-800-361-5653 Monday to Sunday between 8:30 a.m. to 8:00 p.m. for further assessment."

The other two cases are a 51-year-old woman and her 69-year-old husband, who tested postiive at Lakeridge Health Ajax Pickering.



The woman returned to Toronto from Iran on February 22 and went to the Ajax clinic on Friday with a cough, body aches and chills, where she was masked and isolated.



Her husband had a cough, but did not travel to Iran.



All three were discharged and put in self-isolation.



"At this time the virus is not circulating locally," a statement from the government says. "However, given the global circumstances, Ontario is actively working with city and health partners to plan for the potential of local spread. The province continues to carefully monitor this situation and encourage residents to stay informed by regularly reviewing credible information sources."



Williams will provide an update on Monday.



The original three cases of the 11 have been resolved, after the patients tested negative in tests 24 hours apart.
