COVID-19 circumstances involving the XBB.1.5 variant are these days at a low to average stage, with solid or expanding tendencies in all reporting provinces and territories, Health Canada and PHAC stated.
However, a health center in Windsor, Ont., and any other in Montague, P.E.I., introduced outbreaks of the sickness this week.
