In principle, the use time of medical surgical masks is 4 hours. However, due to the serious epidemic situation, under the premise of relatively scarce masks, it can be relaxed appropriately, but not more than 24 hours. For doctors, if they work in the infection department or outpatient department or other important posts, they must change every 4 hours. However, if ordinary people need to go out for shopping, or they can go to work after alcohol disinfection, or 84 spray disinfection for reuse, but it is not recommended to replace them after 48 hours. It is recommended that healthy people wear disposable masks under normal travel conditions, but it is also not recommended to use masks that have been repeatedly used or cross used.
