If you are in a medical institution, please put all used masks in the medical institution directly into the medical waste garbage bag, and these masks will be disposed of centrally as medical waste by a professional treatment organization. If you are at home, for people who are suspected of having infectious diseases, you should hand over the used masks to the appropriate staff when you visit the doctor or undergo an investigation and disposal, and dispose of them as medical waste. For people with fever, coughing, sputum, sneezing and other symptoms or people who have been in contact with such people, it is recommended that the masks be disposed of in the garbage first, and then disposed of by spreading 5% 84 disinfectant solution in a ratio of 1:99 onto the masks. If disinfectant is not available, you can also use ziplock bags or plastic bags to seal the masks and dispose of them in the trash.
