i assume we re looking for asymptomatic people, they won't have quarantined themselves

Most covid19 infections are asymptomatic so unless you treat every day you can't know;)

Given 1/3 people infected are asymptomatic there’s a decent chance you have had it and didn’t know.

Helpful neighboring comments from hours before yours: https://news.ycombinator.com/item?id=23287505 https://news.ycombinator.com/item?id=23288767Unless you want a source that many cases are asymptomatic, in which case you can easily google that yourself.

This kinda makes sense. A lot of people are asymptomatic carriers and there's not much you can do about it

You may have had it and spread it to others. Asymptomatic cases are very common.

They could've had asymptomatic covid and never knew about it?

Isn't a large proportion of cases asymptomatic?

Asymptomatic people can transmit - you can have a small minority be responsible for the majority of new cases

Did you factor in an asymptomatic rate?
