How much do you know about cough etiquette【New Coronavirus Popular Science Knowledge】(496)

　　The droplets produced by sneezing and coughing can spread bacteria or viruses, and then spread diseases. Even if a healthy person sneezes or coughs, the droplets produced may also carry bacteria or viruses!

　　Cough etiquette is to physically block the respiratory droplets ejected from coughing or sneezing with the help of shields to reduce the spread of respiratory droplets and droplet nuclei in the air, thereby reducing the risk of infection of the surrounding people.

　　During the new crown pneumonia epidemic, take personal health protection and pay attention to cough etiquette.

　　No.1

　　When you cough or sneeze, avoid crowds as much as possible and cover your mouth and nose with a tissue or handkerchief to prevent saliva from splashing.

Avoid covering your mouth and nose with your hands, as this will make your hands contaminate with germs and spread the germs to others.

　　No.2

　　If you are in a hurry and are too late to prepare, you can bend your elbows close to your face and cover your mouth and nose with the inside of your clothes sleeve.

This action can block the sprayed droplets on the elbow skin or clothes, and this part is relatively dry, and it is not easy to contact other public goods, which can effectively block the spread of pathogenic microorganisms.

　　No.3

　　Do not throw away the tissues that have touched your mouth and nose when you cough, but should be thrown into the trash can.

　　No.4

　　Wash your hands promptly after coughing or sneezing or use a no-wash disinfectant to disinfect your hands.

　　No.5

　　Clothes contaminated by respiratory secretions should be washed in time and exposed to the sun for drying to achieve the purpose of disinfection.

　　Notice

　　1

　　When sneezing or coughing, try to keep a distance of more than 2 meters from others. If you are in crowded places (such as on the subway in the morning rush hour), you can wear a mask to avoid spreading to others.

Because when we sneeze or cough, the droplets produced spread quickly like a cloud, which can bring bacteria or viruses to a distance of about 2 meters.

　　2

　　You do not need to remove the mask when you sneeze or cough, but you can change it in due course; if you are not used to it, you can remove the mask and cover your nose and mouth with a face towel or elbow.

　　3

　　Don't speak too loudly to avoid "foaming and flying".
