Useful info from The Conversation, Here’s where (and how) you are most likely to catch COVID – new study. Useful, but not very surprising:
Bottom line: indoors is OK, but only if you are a monk in a drafty monastery with a rule of silence? And returning to in-person classes is a bit dicey?
What does it mean? I have trouble understanding these percentages. The author writes “gives a percentage likelihood of becoming infected in different situations”. My Little brain does not compute.
I totally agree that % of what is always a right question to ask. But we can at least look at this as a measure of relative risk, can’t we?
More useful seems to be Table 2B in the paper where they estimate the time in hours to be at risk of an outbreak under the same circumstances.
Maybe…But the bottom line seems much the same (if starker?): outdoors good, indoors bad unless well-ventilated and silent. The full paper is here.
