By the by, two random interjections:
1. At work, a university, we've been told they won't be cleaning rooms inbetween sessions as they will be sprayed with a 'mist' that kills the virus for 4 weeks. It's as if Donald Trump became our VC...
2. I had my own Occ Health this discussion about whether I was up to teaching face to face due to a couple of medical conditions. Fwiw, the OH guy is great and provides report that are helpful in union casework. Anyway, he mentioned the usual point that face masks only stop you transmitting to others. However there are medical grade masks that do provide protection to the wearer and recommended I wear one of those. Rather begs the question why supermarket worksers and others haven't been wearing these for months...
