https://www.cnn.com/2020/04/01/europe/iceland-testing-coronavirus-intl/index.htmlThis is interesting. 9000 tests of self-selected population. 1% positive (means around 90) and half of them (45) asymptomatic. Not sure if the sample size is large enough, but it's definitely interesting. It's hard to say without more data. But it could mean that in a country with very low infection rates, still asymptomatic people have already been infected at some rate. Meaning that in a country with huge infection rates, maybe the infection rates are really a lot higher than we think. And maybe hospitalization and death rates are lower than we think.
Also this from the article
Stefánsson wonders whether mutations in the virus are "responsible, in some way, for how differently people respond to it -- some just develop a mild cold, while some people need a respirator," or whether a person's genetics dictates their condition.
"Or is it a combination of these two?" he asks.
Something I've been wondering aloud for a while
