Also,
@OwnedbyChanter what do you expect people to do?
My boyfriend is on the lung transplant list, he has somewhere between 20%-25% lung function, grows his own bacteria in his lungs, can't digest any food without tablets and is on over 100 tablets a day - many of these tablets, he has to take with specific good to ensure the fat or protein ratio. He has to eat approximately 1,500 calories extra than the average person. He does hours of medical treatment a day. To top it all off - he's 37 years old and was 'supposed' to live until he was 2 years old at the most.
A common cold could kill him. The coronovirus certainly could. We rely on people allowing us to self isolate and keep themselves away from us when they have a cold. So yes, I'm rather keen other people self isolate when required.
Every Flu season, we have to ensure we have enough food, medication and whatever else we need to ride out someone close to us having a common cold (including a lot of hand wash and anti bacterial gel) - so yes, we're taking extra precautions this year.
P.S He also doesn't look ill or otherwise vulnerable and is encouraged to be as independent and active as possible so you'd have no idea by just looking at him either.
