I remember an article or two a while ago (March?) which said that the covid stayed on surfaces for up to 14 days. But later it was shown that it was just remnants of the virus that were detected and were not infectious. Don’t know how these experiments or results compare - I don’t have time to read the whole article.
Also, I notice this is from the November 2020 issue of the journal, so maybe a little time-travel is occurring here as well. :)
