What can you do to avoid getting the flu?

Here I am talking with Ray Suarez on HITN listing the basic stuff -- we don't know how flu is transmitted, so if you want to reduce your chances 1) wash your hands frequently (and don't touch your face), 2) stay as far away from sick people as possible, and c) wear a respirator if you have to get near sick people. Also, keep the windows open or otherwise get as much dilution ventilation as possible (either outside air or HEPA filtered air unless you have very special UV lights).
