S.W.
H1N1 presents with a dry cough and chills and fever. He would not be breathing very well. He would be VERY sick. I would watch and see. If you are heading back home in the next day or so then treat the symptoms and follow up with his doctor on Monday providing he does not get any worse before then. Steam, baby vicks rub, extra fluids and some extra TLC. If he isn't fevered or in pain, hold off on the tylenol, it does nothing for a cough anyway.
