VANCOUVER -- Health officials have declared an outbreak of COVID-19 at Lions Gate Hospital after 16 patients and a staff member there tested positive for the disease.

The outbreak is on the fourth floor of the hospital, in both the 4 West and 4 East units, according to a news release from Vancouver Coastal Health.

The west unit is a "sub-acute medicine unit" and the east unit is an acute medicine unit, the health authority said.

All non-essential visits to the fourth floor of the hospital have been suspended as a result of the outbreak, and the units are closed to new admissions and transfers, according to Vancouver Coastal Health.
