My S had it and he was very sick. I took the tamiflu too as I was about to have surgery. When I got to the hospital and told them that I was taking Tami as a preventative the nurse raced straight out of the room and grabbed a mask for her and for me. (Just a slight overreaction as I didn't actually have it and by the time I got to hospital S was completely well.) Surgeon didn't see the problem and I was allowed to remove the mask.
