In a troubling development for a neighbourhood with one of the country's most vulnerable populations, a case of COVID-19 has been confirmed on Vancouver's Downtown Eastside.

The Salvation Army, which operates the Harbour Light transitional home and addiction treatment centre, said one of its clients tested positive on the weekend.

Mike Leland, a spokesperson for the Salvation Army in B.C., wasn't able to share any information about how the person at the facility contracted the virus or the severity of their symptoms, but he said significant measures have been put in place to prevent the virus's spread.

On Wednesday, Vancouver Mayor Kennedy Stewart, highlighting the other public health crisis in the city, overdoses, said there were no confirmed outbreaks of COVID-19 on the Downtown Eastside.

Provincial health officer Dr. Bonnie Henry has used the term "outbreak," to describe even single cases in long-term care facilities, but it's not clear whether that language would apply to a centre like Harbour Light.

Leland said Vancouver Coastal Health staff have been at the centre since the case was confirmed, doing an education session with clients and staff and rigorous daily cleaning that's set to last 14 days.

There's also continued monitoring and testing of staff and clients.

"We're really working diligently to make sure this thing does not explode on the Downtown Eastside, and so far, so good," said Leland.

He said testing has been carried out at Harbour Light and results for 19 clients and staff have come back negative, with five additional test results pending.

"Obviously, the Downtown Eastside, we're dealing with our population's most vulnerable citizens," said Leland. "We're super cognizant of the health of the people in and around our facility, so we just continue to strictly enforce social distancing."

Leland said the person who has COVID-19 was isolated in part of the building at 119 East Cordova St., before being moved offsite by health officials.

He said there have not been any other confirmed cases at any Salvation Army facilities in the province.
