The jury is very, very much out on that. The 70% number bandied about is extremely naively calculated, it assumes 0 pre-existing resistance or immunity (Which we now know exists), and it assumes all humans are homogenous sphere-shaped balls floating around in a gaseous society, which is also obviously not true.
There are countless reports and studies on transmission among children in school settings, and they pretty much unilaterally state that there's very little spread happening there, contrary to everyone's "gut feeling" about kids being snot-nosed petri dishes.
- mattycakes 6y agoYeah, the article completely disputes this point. I suggest you read the section titled "How high is the threshold for SARS-CoV-2?"
- henrikschroder 6y ago> Yeah, the article completely disputes this point. No, the article explicitly says "Estimates of the threshold for SARS-CoV-2 range from 10% to 70% or even more", and then it sort of handwaves away any studies showing lower numbers, and highlights the ones showing the higher numbers. That is pretty much the definition of the jury being out on the matter.
- xyzzyz 6y agoMoreover, this 70% number is based on SIR models, which observably do not match the dynamics of our predicament at all.
- exogeny 6y agoI'm going to guess you didn't read the article.
- henrikschroder 6y agoYou guessed wrong.
- exogeny 6y agoOK. New guess: you didn't understand it, or willingly choose not to understand it, because you've already made up your mind.

You've misunderstood whatever you've read. > and they pretty much unilaterally state that there's very little spread happening there This is untrue.

(But there are many others showing that schools increase spread of covid).
- lbeltrame 6y agoYou might want to read the discussion section when they mention their modeling of schools. There is an important limitation to be wary of.
