Even as coronavirus was devastating populations around the world last year, doctors and public health officials noticed something else was missing – there was almost no flu. Many believe that measures taken to help control coronavirus also prevented the spread of influenza. Experts think the 2021-2022 influenza season might be a bad.

These exposures might not be enough to make people sick, but they’re enough to remind the immune system to keep up its defenses. See the article here.
