The virus is highly contagious and is currently spreading rapidly. Especially if you are in an area where the virus is widespread, the best way to prevent illness is to avoid exposure to the virus. This means avoiding close contact with people who are infected and public spaces where you can come into contact with many people. You should follow any national or local guidelines around social distancing, staying at home, and wearing masks. You should regularly wash your hands and disinfect any frequently touched surfaces.
