The health authority said in a statement that the latest outbreak was at New Vista Care Home, which is run by New Vista Care Society.
A Fraser Health Rapid Response Team is on site and communication with residents and families is ongoing.
Fraser Health says the outbreak is limited to one unit in the building and the staff member who tested positive is self-isolating at home.
The health authority says it is working with staff to identify anyone who may have been exposed.
This is the second time that a COVID-19 epidemic has been declared at New Vista Care Home. A previous epidemic was announced there on April 22 and declared over on June 8.
The new outbreak follows two separate outbreaks that were declared on the George Derby Care Society campus in Burnaby.
A staff member from Derby Manor, an independent living center, and a resident of the George Derby Center, a long-term care home, have each tested positive for the coronavirus, Fraser Health announced Friday.
Although located on the same complex, the two facilities are housed in separate buildings, and Fraser Health said on Friday there was “no evidence” that the two outbreaks are linked.
The number of COVID-19 outbreaks in healthcare facilities in British Columbia has increased significantly since Tuesday. At that time, there were three outbreaks in health facilities across the province. As of Friday, there were seven, and Sunday’s announcement of the New Vista outbreak brings the total to eight.
Most of the recently announced outbreaks have been in a single confirmed case at the time of their announcement and special response teams have been set up.
“Even a single case that we are taking very seriously in our health care system,” said Dr Bonnie Henry, provincial health officer, at her press conference Thursday.
