I'm not sure, but I think the medics' masks are more to prevent transport in the other direction, such as someone accidentally spraying spittle over a compound fracture.
Hmm yes, you're probably right. Hazmat suit from now on then ;-)

When I was in north China, a lot of people wore cotton masks. The air was pretty dirty, and it was bitterly cold. One doctor told me not to wear a mask, as it would increase the chance of me getting sick. Wearing a mask caused a lot of warm condensation in the cloth covering the face, which I think may be a good breeding ground for whatever is in the air, or already in your mouth/nose.
I did wonder about that actually. Presumably this isn't a problem for medics who change their masks regularly.

That was interesting to know about the immune response to colds though. I had often wondered why people vary so much in their responses. Some of my Asian friends get a strong response for 24-48 hours, and then are fine. I usually will be crappy for 1-2 weeks, which I think helps to get futher infections.
I'm the same; I usually feel run-down and lethargic for about a week, then for 2 days feel so ill I want to die. Interesting things, viruses. There are only two ways it can play out for the virus: the host wins and the virus is destroyed, or the virus wins, the host dies, and is no longer able to sustain the virus. Either way the virus dies. So at least the rhinoviruses have evolved to exploit our immune system to ensure it is transmitted to a new host before its inevitable destruction. Clever!

Personaly, after spending a year or so in China, I don't get nearly so sick any more. It's a real kick for the immune system.
Really? How so?
