I'm another who has been ill with flu/cold symptoms. Was first ill with fever, sore throat, and dry cough about a fortnight ago and then picked up for a week but yesterday I felt so awful I ate nothing and ended up taking to my bed.
Odds are overwhelming in favour of my virus being a common garden variety but what if it's not? DH commutes on the tube (and he had this virus first) so it's not as though an absence of local cases mean much.
I think the limited testing resources are one of our biggest problems. I'm not worried that my virus is suddenly going to spiral into dangerous territory but I am constantly aware of the 'what ifs' as I go about life as usual. It's currently not reasonable for people like me to stay away from work etc on the remote off chance that a nasty cold is something more sinister; if there was a simple quick test available to everyone we'd be able to know for sure and isolate ourselves accordingly.
Obviously anyone with symptoms should be taking careful hygiene steps to protect others regardless (and not just during a pandemic) but I'd hate to be responsible for unwittingly spreading CV about.
It's frustrating to feel so powerless.
