There is currently no vaccine to prevent 2019-nCoV infection. The best way to prevent infection is to avoid being exposed to this virus. However, as a reminder, CDC always recommends everyday preventive actions to help prevent the spread of respiratory viruses, including:
Avoid close contact with people who are sick.
Avoid touching your eyes, nose, and mouth with unwashed hands.
Stay home when you are sick.
Cover your cough or sneeze with a tissue, then throw the tissue in the trash.
Clean and disinfect frequently touched objects and surfaces using a regular household cleaning spray or wipe.
Follow CDC’s recommendations for using facemask.
CDC does not recommend that people who are well wear facemask to protect themselves from respiratory viruses, including 2019-nCoV.
