Thank you for sharing this. It would be better if people would stop trivialising this disease based on their own lack of experience. Another musician friend of mine caught it at the same time as you and was in ICU for three months. He has suffered long-term damage. Before I read your article, I read another account of someone who lost their mother. A lot of people have died and are dying (>3000 a week in the UK, currently), but his account was particularly sobering because he described how his mother suffered in her last week and it was utterly horrific. Hard to imagine a worse torture.
My view is that we should, as much as we possibly can, be observing first principles of transmission of respiratory viruses. The first one of these is 'stay away from other people'. When that's impossible, limit the time and make sure that there is a fresh air supply. It doesn't matter if you're ten metres away, if you're in a room for three hours together and there is no new air. Everyone should be wearing face coverings at all times when they are anywhere near other people. Singers and horn players?
Rehearsal conditions break all the basic 'rules'. It may seem like a low risk, but when assessing risk, it's not just the likelihood that should be taken into account, but also the severity. For Covid, that's potentially death or possibly worse.
So my bands have not rehearsed since March, apart from those of us who are on Jamulus online. I have told my fellow band members that I will not rehearse in person nor play a gig until new infections are below 100 a day.
