There is still an outbreak of novel coronavirus pneumonia, so in daily life, the public, especially cold patients, learn the correct way to cough and sneeze to prevent droplet transmission. 1. When a cold patient feels about to sneeze or cough, use a tissue or handkerchief to cover the mouth and nose. 2. If you don’t have a tissue, you should turn your head around and punch at the crook of your arm when sneezing, and use your elbow to cover your nose to sneeze, instead of Cover your mouth and nose with your hands. This will prevent snot from splashing and the virus from attaching to your hands, thus reducing the chance of spreading it outward, and coughing in the same way. Source: Dr. Yurei
