I think there are a huge number of infections which were not caught by testing, due to being before the pandemic officially started (#earlycovid [0]), or because they were asymptomatic (ex: large percent of the pregnant women who showed up at the hospital to give birth in NYC in March 2020). I think I caught the 'rona in December 2019 or January 2020, headache for a day or two then I was fine...

Virulent coronaviruses usually burn themselves out without help. This one is more potent than the earlier ones, but if people are healthy they'll be fine.
