@jeffro: yet, despite the measures, COVID continued spreading. The measures did nothing but aggravate the situation in most cases, the states and countries with the strictest measures had the most spread.
If you want to know what happened to the flu, look at the CDC statistics. The COVID published numbers and tests (https://www.cdc.gov/coronavirus/2019-ncov/lab/multiplex.html) INCLUDE the cases of flu and pneumonia (https://www.cdc.gov/nchs/nvss/vsrr/covid19/index.htm).
Whereas before, we had literally hundreds of people dying monthly from flu, and over 1000 during flu season, we now have zero or single digits dying from flu, because they get lumped in with COVID. Simple reason, as COVID care is 100% paid for by the government, this is turning into government run healthcare.
