Health officials say an outbreak of the highly-contagious norovirus may be nearly over at two Metro Vancouver hospitals, but the virus has also appeared in Kamloops.

More than 40 people have been quarantined at the Ridgeview Lodge residential care facility in Kamloops as they recover from an outbreak of the bug.

Lodge General Manager Dana Levere says 22 residents and 22 staff have been segregated since the virus appeared in late December.

At Vancouver General Hospital, the virus struck an acute care ward and a second unit, and officials say if there are no new cases, the outbreak will be considered over on Friday, 96 hours after the last case was diagnosed.

Two wards of Royal Columbian Hospital in New Westminster were quarantined earlier after at least 18 people were infected by the virus, and that outbreak could also be declared over on Friday if there are no new cases.

There have been additonal outbreaks at five Metro Vancouver daycare centres and a half dozen regional facilities in recent weeks involving the infection, which is also known as Norwalk virus.
