Ordinary people wear masks to protect themselves and prevent others from transmitting pathogens to themselves through droplets. If you wear a mask just to go in and out of ordinary places, such as going to the supermarket to buy food and going to the park for morning exercise, the mask can be reused.
The mask you take off can be folded inward, with the colored side facing outward, put in a clean bag, and then take it out to wear when you use it. Wash your hands before wearing a mask and after taking off the mask, or disinfect your hand surface with an alcohol-based hand-free disinfectant.
Extended data:
If you go to the hospital for treatment or enter the hospital, no matter whether the user is a patient or a healthy person, the mask belongs to medical waste. It should be thrown into the yellow trash can set up in the hospital and collected by the hospital for centralized harmless treatment.
Ordinary citizens wear masks when they go out, so it is impossible to judge whether they have touched novel coronavirus. From the point of view of protecting public life and health to the greatest extent, it is suggested that the used masks should be disinfected with alcohol spray, put into sealed bags such as plastic bags, and then discarded in closed trash cans.
