3. If you sneeze or cough, cover your nose or mouth, Bassett said. He also recommends avoiding rubbing or touching your eyes and nose. "Don't touch your face. Cold and flu are often spread by hand-to-hand contact, so avoid directly facing an individual who is coughing and sneezing." If you do sneeze into your hands, make sure you clean them, and do this EVERY time you sneeze or cough.
