I heard a stat that in the southern hemisphere's 2019 flu season, the rate of flu tests that came back positive was something on the order of 13%. This flu season, the test positivity rate is 0.6%. Obviously lockdowns and even significant social distancing aren't going to happen for the flu, but I think you're right that we could easily do so much better when it comes to other transmissible diseases, and I hope that at the very least masking sticks with us.
