I've taken and given many classes on influenza (the flu). I could tell you all sorts of things about the 1918 virus and the work being done on it now, and how it relates to the bird flu that's currently circulating around Asia and Europe. I could tell you the components of a flu virus and how it fuses with host cells. I could also tell you about the attempts to creat vaccines and drugs to combat the flu (and why one of them work very well). Unfortunately, all this knowledge doesn't help a fig when I've got the flu.
I'm sorry, M, if in a few days you start running a fever. And I'm sorry if any of the people I came into contact with at the tea party get sick too. This is no fun and I wouldn't wish it on anybody, not even... well, there's no need to be petty. I hope to feel better soon. I've got dancing to do.
