Wear a mask, sit as far from everyone as possible, and if you can, sit next to and open a window. (For you, that is. I agree with you about people showing symptoms. No way I would ever get on public transport if I suspected I might have it.)Yes, although I've been inoculated against things like measles and cv wasn't in cornwall (although just on the cusp) last time I travelled on it.
I wonder how many people would catch the bus if they were showing symptoms - I certainly wouldn't, nor a taxi nor a lft with a friend (I presume it'd have to be an ambulance?) but as you say nurses and also patients would use it and with ppe being as it is in the UK I'd be somewhat concerned at leakage.
There is an interview on one of the threads here with one of the South Korean doctors in charge of SK's c19 response, so not a bad person to ask, and he describes how you can catch it from aerosol rather than droplets only in certain conditions. Referring specifically to the church gathering in SK that caused a mass infection, he described how singing releases a lot more of the virus as aerosol than just talking, but also how it builds up over time in an enclosed, or partly enclosed, environment. (Singing, lots of people close together? Sounds like football matches might be spectator-free for a while. ) You need a certain level in the air to become infected - something like a few hundred thousand viral particles needed to infect you. My suspicion is that this is exactly what happened in crowded London buses pre-lockdown, building up over time with lots of infected passengers and the drivers catching it from breathing that infected air over a long period. We need loads more information, basically, cos in a bus with, say, 10 people and its windows open, the chance of aerosol infection may be effectively zero. Lots about that we need to know.
