> flu numbers are much lower if not vanishingly small, suggesting people are in fact largely complying with mitigation efforts The flu viruses are a different class of virus (rhinovirus) from SARS-CoV-2 (coronavirus) and could be expected to be affected differently by mitigation efforts. I don't know that the much lower flu numbers tell us that people are wearing masks properly; they could be due simply to social distancing and people staying home. Also, AFAIK there is not significant evidence of transmission of flu by asymptomatic people, whereas there is for COVID-19, so it is easier for people to avoid transmitting flu by self-isolating if they have symptoms.
