York region case presents a 'number of complexities'

Dr.Karim Kurji, York Region's medical officer of health, told reporters at a news conference on Saturday that the 34-year-old woman in the first casetravelled from Iran with her husband and toddler on Tuesday, with a layover in Denmark. She was not wearing a mask.

He said this particular case presents "a number of complexities" as a result of the woman's travel.

The woman developed symptoms on Tuesday,before her last flight from Copenhagento Toronto on Wednesday. She took three flights in all.

Kurji said the woman then took a GO bus from Toronto Pearson International Airport, Terminal 1, on Wednesday afternoon. She was travelling eastbound, sitting in the upper deck, and her final destination was the Richmond Hill Centre Terminal.

People who were on the following flights and the busmay have been exposed to the positive case of coronavirus,Kurjisaid:

• Passengers in the business class section of Qatar Airways flight QR 483 and QR 163 on Tuesday.
• Passengers in the business class section ofAir Canada flight AC 883, from Copenhagen to Toronto,on Wednesday that landed at 2:55p.m. at Pearson.
• Riders on GO Busnumber 40 eastbound and who sat on the upper deck of the bus on Wednesday from Pearson Airport to Richmond Hill Centre Terminal. The bus left Pearson at about 3:55 p.m.

Anyone who was in these areas is urged to contact York Region Public Health at1-800-361-5653, from Monday to Sunday, between the hours of8:30 a.m. to 8:00 p.m., for further assessment.

"The individual is currently in self-isolation, recovering at home, as a result ofthe co-ordinated and collective efforts of our healthcare and public health system,"Kurjisaid. "The individual was quickly recognized, assessed and isolated."

Kurjisaid York Region Public Health is aggressively tryingto trace all close contacts of the woman and people who may have been exposed.York region public health officials are trying to get the flight manifests of the planes on which she travelled.

"There has been a number of areas where exposure could potentially happen," he said.

Hospital says it was prepared

Mackenzie Health was prepared to receive a coronavirus case and "all the proper precautions" were already in place when the woman in the first case arrived, according to Dr. Danny Chen,lead in infection prevention and control for the hospital, in a memo to staff obtained by CBC News.

He thanked the emergency department for "promptly identifying and isolating" the person.

"It is understandable that news of a presumptive positive case here at our hospital may cause concern for you. Because of the protocols in place, there were no staff, patient or visitor exposures related to this case," he told staff. "This reinforces the importance and effectiveness of our protocols."

He said staff and patient safety is paramount.

"Although the situation surrounding COVID-19 continues to change and evolve and more cases of COVID-19 will be identified going forward what hasn't changed is the fact that we're prepared, and that staff and patient safety will always remain a priority at Mackenzie Health."

According to Chen, York Region Public Health contacted the hospital on Thursday before the person was sent to its emergency department.

Officials worked out a time for the person to go to the emergency department, the person arrived wearing a mask, presented symptoms of coronavirus and was immediately put on "airborne/droplet/contact" precautions, he said.

"A physician assessed the patient and determined that admission to the hospital was not required due to the condition of the patient and the low severity of their symptoms," Chen said.

"The patient was advised to self-isolate until the test results were received and to return if symptoms worsened."

The hospital received confirmation that the case was presumptive on Friday evening, he said. That case has since been determined to be positive.

In a news release on Saturday, the hospital said: "Hospital operations are running as normal."
