For some people their infection with covid is going to be mild, and their infection with a cough or cold is going to feel to them similar to covid. But for other people covid is very much more severe than a cough cold.
I have cancer, I'm going through chemo. I must not catch a cold, because it could be really serious. But I really must not catch covid, because it could kill me.
I'm not expecting society to live in lock down to accommodate me, but if an event asks people to do lateral flow testing before attendance, and someone tests and is positive, I'd like them to not attend, or attend with masking and social distancing. I don't want them to attend, not mask, not socially distance, and then near the end of the event say "oh, by the way, I tested positive for covid this morning". I don't attend events because this is a thing that people do.
