School buses as petri dishes
May. 23rd, 2020 03:36 pmPlans are being put in place for children to attend school, sooner in England, plausibly August here in Scotland. I have some concern about transportation. We have one car and the drivers among us will probably need to be in one city and our youngest goes to high school in another, thus via the school bus that comes through the villages.
I wear a mask as a helpful precaution, a nice polka-dotted one today. However, my impression is that SARS-CoV-2 may be easily exhaled around the edges of normal masks, may contagiously hang in the air in a very fine mist and that, in transmission studies, extended periods in enclosed spaces are the worst. So, short of full-face respirators, I fear that frequent commuter use of even socially distanced buses could easily lead to infection. Perhaps I am worrying too much and, by the time the children return to high school, it will happen in a relatively safe way.
