According to the CDC, here are ways to prevent the spread of respiratory diseases like coronavirus:
You should remember to clean and disinfect frequently touched objects and surfaces using a regular household cleaning spray or wipe. Also, make sure you wash your hands often with soap and water for at least 20 seconds, especially after going to the bathroom, before eating, and after blowing your nose, coughing, or sneezing. If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol. Always wash hands with soap and water if hands are visibly dirty.
If you are well, the CDC does not recommend wearing a face mask to protect themselves from respiratory diseases, including COVID-19. Face masks should only be used by people who show symptoms of COVID-19 to help prevent the spread of the disease to others. The use of face masks is also crucial for health workers and people who are taking care of someone in close settings, such as at home or in a health care facility.
