But most viruses spread when asymptomatic. That is not shocking though most people don’t understand that. I wouldn’t count on information now until some more weeks have passed.
“But most viruses spread when asymptomatic”
That was the point of the original article. The only proof they had of that so far was incorrect.
I read various sources that said most flu strains can be transmitted 24 hours before symptoms, and SARS was 48 hours. Both can also survive about 24 hours on a hard surface - or longer.
