The worst may be over when it comes to respiratory illnesses this winter.

Ontario’s Chief Medical Officer of Health, Dr. Kieran Moore, says the number of flu, COVID and RSV cases is beginning to decline.

In an update, Dr. Moore states flu cases peaked at the end of November, and the number has since fallen.

RSV cases have stabilized and starting to show a drop.

With COVID, Dr. Moore says there are signs of improvement after a rise in numbers over the holiday season due to the B-Q.1 variant.

There is still concern about a variant of COVID, identified as XBB.1.5.

Dr. Moore says some parts of the province are seeing an increase in cases related to the more transmissible variant.

He adds keeping up with our vaccinations is still the best defence against COVID and its variants, especially for those at increased risk of severe infection and for anyone who has not received a booster or been infected in the past six months.
