Three people at the National Microbiology Laboratory have tested positive for the coronavirus, staff at the Winnipeg facility were told via email on Thursday.
The three, who tested positive while on site, are now in isolation, lab executive director Steven Guercio said in the email, which was obtained by CBC News.
“Manitoba Health has initiated contact tracing,” Guercio said, referring to the practice of finding out everyone an infected person could have contacted prior to their test.
“As a proactive measure, Facility Occupational Health and Safety has initiated a risk assessment and will ask potential at-risk contacts to isolate at home pending full contact tracing by Manitoba Health,” Guercio added.
“Close contacts identified through contact tracing will receive direction from MB Health on testing and isolation requirements.”
Guercio also told staff the lab’s management “understands that this news will create concern” and advised them to contact employee assistance if they need to do so.
All staff were also instructed to wash their hands on their way out of the building.
Close contacts tested
Guercio’s office deferred comment to the Public Health Agency of Canada (PHAC), which is responsible for the microbiology lab.
The agency was not immediately available to comment.
Manitoba Shared Health also deferred comment to the agency.
A Shared Health spokesperson said the province only comments on infections when there is a public health concern.
The head of the union representing scientists and researchers doesn’t know if any of the infected people are her members, but Debi Daviau said she’s been told at least one is a lab worker.
Daviau, president of the Professional Institute of the Public Service of Canada, said Health Canada has done contact tracing on all three — any close contacts were tested and sent home, and are expected to get their test results tonight or tomorrow.
Non-close contacts were asked to stay at work for now but they were also tested. If they are positive, they will be sent home for self-quarantine.
Research includes coronavirus
Work at the lab includes research on SARS-CoV-2, the coronavirus that causes COVID-19.
Researchers are trying to find an appropriate animal model for research as they work on a vaccine and treatment for the respiratory illness, Daviau said.
“They are working around the clock. Their work is critical. They are working with the virus, so the potential for exposure is high,” she said.
“These members are some of Canada’s unsung heroes.”
The NML had arranged for a drive-thru testing site at the lab for staff and their families, Daviau said, adding PHAC is handling the situation well.
“PHAC responded rapidly, and fortunately, due to onsite infectious disease experts, they’ve implemented responsive testing, tracing and isolation measures. We appreciate the urgent action and support for the safety of the employees at the site,” she said.
Some staff at the lab have chosen to work at home during this time, but Daviau said others have told her “the work is too important” to close the building.
Meanwhile, the union representing staff including lab technicians as well as building operations, administrative and program staff is waiting to find out if any of its members have been infected.
“Our concern is, first and foremost, the health and safety of our members and all employees at the NML,” Shimen Fayad, acting national president of the Union of Health and Environment Workers, said in an email.
