Experts suggest that whether you go to a hospital or visit a patient, all masks used in medical institutions should be directly put into medical waste garbage bags. These masks, as medical waste, will be centrally disposed of by professional disposal agencies. People who are suspected of having an infectious disease should hand over the used masks to the corresponding staff during medical treatment or investigation and disposal as medical waste. For ordinary people, because of the low risk, the used masks can be directly thrown into the trash. After handling the mask, remember to wash your hands carefully.
