Asymptomatic spread nonexistent?
"Our results indicate that silent disease transmission during the presymptomatic and asymptomatic stages are responsible for more than 50% of the overall attack rate in COVID-19 outbreaks."

- dragonwriter 6y agoSure, if you add presymptomatic and asymptomatic spread you get a large number (because the most infectious period is the presymptomatic period right before symptoms develop.) That doesn't even begin to contradict asymptomatic spread, distinguished from presymptomatic spread, being rare to nonexistent. Usually, this makes little difference because you can individually distinguish the two only in retrospect, but when you have a population (like children) that demonstrably has a much lower propensity to develop disease symptoms when infected and a much higher propensity to remain asymptomatic, it makes a big difference.
