Liz - I'm sure the doctor won't think that you are silly for taking DS to see him (or her). I have taken my kids after they have had temps for a couple of days a few times and it has always been a virus like a cold and the doctor always says that he is happy enough that they don't need antibiotics and we just have to wait it out but always says just because he is happy today, doesn't mean that if things get worse tomorrow he doesn't want to see them again. I have found doctors to always be very supportive, especially when small children are involved.
As for face masks - my brother works for a zinc refinery owned by some korean men and they apparently have been wearing face masks for the last couple of weeks. My brother said they have drawn pictures on the front of them like cat whiskers and stuff. I had to have a chuckle - I think that would be hilarious. I think the masks are just a hygiene thing - apparently in other cultures it is a HUGE offence to go out in public when sick. Not a bad practice really :)
