When sneezing, droplets containing viruses can be dispersed into the air within a range of about 2 meters, and people around you may be infected by inhaling these droplets. Therefore, the following points should be noted when sneezing: 1. When sneezing, you should cover your mouth and nose with tissues or elbows, not directly with your hands; 2. Tissues used for sneezing should be put into a covered garbage can; 3. If you cover your mouth and nose with your hands when sneezing, you need to wash your hands thoroughly with soap or hand sanitizer; 4. When sneezing symptoms occur daily, it is recommended to wear a disposable medical mask; you should not take off your mask when sneezing; and you should change your mask after sneezing.
