More people in Manitoba have come down with the flu so far this season, compared to past year, health officials warn.

Manitoba Health says the number of lab-confirmed influenza cases continues to rise steadily and has likely not peaked.

Twenty-one cases of influenza A infection, and two cases of influenza B, were reported from Dec. 23 to 29, the department said in a release Wednesday.

The province is urging all Manitobans to get the flu shot, especially seniors, pregnant women, children under the age of five and others at increased risk of getting the flu.

Officials say they have an adequate supply of flu vaccines Fluviral and Agriflu, which cover the most common flu viruses.
