It sounds like the Norwalk virus and the only more common virus is the common cold. It is transferred from hand to mouth and it develops in your intestine. It can also come from improper food handling or raw seafood. When we go on trips I carry the Lysol disenfectant wipes and spray. I wipe everything in the cabin, including the remote control, light switches and the bathroom .. I don't want to be sick either and so it is time well spent to do a quick wipe down .. Never use the public bathrooms and wash your hands all the time, carry your own purell bottle and be a little over zealous.
