Some will argue that we didn't have a flu season because all flus were counted as Covid19. Others will argue the Covid19 strains were more powerful and destroyed the seasonal flu. Masks only help reduce the output of germs related to coughing or sneezing. And that's only if the person coughing or sneezing utilized their mask correctly covering from mid nasal passage down to the chin. Overall I agree with Phil the masks were negligible at best.Funny we didn't have a flu season for 2 years so it absolutley did help. Plus how would you know if it didn't? Plus we live in Canada not the US. Every state did something different to control Covid. Plus I believe the US is starting the whole deal again. I'll believe a doctor and health professionls over the media anyday.
