Answer:
The best way to protect yourself from contracting coronaviruses is by using the same daily habits that help prevent the spread of many viruses, including the common cold and the flu. To help prevent the spread of disease always:
Avoid close contact with people who are sick.
Wash your hands with soap and water frequently. Wash with soap and warm water for 20 seconds. If soap and water aren't available, use an alcohol-based hand rub.
Avoid touching your eyes, nose, and mouth with unwashed hands.
Stay home when you’re sick (and keep sick children home from school).
Cover your cough or sneeze with a tissue, then throw the tissue in the trash and wash your hands. If you don't have a tissue, cough or sneeze into your upper sleeve or elbow, not your hands.
Clean and disinfect frequently touched objects and surfaces
