| Covid is caused by a "corona virus". The Flu is caused by the "influenza virus". So even though they are both contagious respiratory illnesses, they are caused by completely different viruses. The reason we've seen far fewer influenza cases these past 2 years isn't related to the 2 viruses out competing eachother. It's much more likely that the pandemic measures we've had in place, over most of the world, like social distancing, mask wearing, lockdowns, closed borders, etc., has had a greater impact on the flu, because it isn't as contagious as covid. When we remove the pandemic measures, we're probably going to see the usual flu numbers again. Maybe even worse than normal, for the first couple of seasons. Since we haven't been as exposed to the flu for 2 years. |
