I got flu the week SARS turned up in the UK - but was so poorly I got home, collapsed and didn't move for three days (literally, didn't even need to get up to go to the loo!) (sorry if tmi), had high temp for a couple of weeks and was wiped out for a couple of months.
It wasn't until about 6 weeks afterwards that I happened to be reading about it and read down a list of symptoms of SARS that I'd had every one of that I vaugely wondered if I had had SARS but then read the list of ordinary flu symptoms and it was pretty much the same so never really gave it another thought. In hindsight, maybe I should have checked something out at the time as I was on a course with a large contingent over from SE Asia, but once I'd collapsed that was it, DH didn't know about all the SE Asians on the course, I didn't know about SARS until I finally got much better and started listening to/reading the news again, by which time it was to late to bother with.
On a sort of related note, there seem to be quite a few people that have been on TV news with swine flu that seem to have more of a cold than flu. They are up and about and dressed and talking... Only thing I remember about having flu was that I wasn;t going anywhere other than staying in bed, you could have waved a million pounds under my nose and I wouldn;t have cared or even noticed.
And if the media is getting all hyped up over this, why does nobody even seem to mention 'ordinary' flu which kills lots of people around the world every year?
