I have been caring for people in my house with H1N1 for a week now. I've been expecting to come down with symptoms all week, but nothing so far. Yes, I've been washing my hands a lot, but I just have to have been exposed by now.
So what's going on? I remember getting a swine flu vaccine in '76. Could that be affording me some protection today? Is my hand washing just that good? Could the incubation period be really long?
