If you live in a building or in an office, you need to take an elevator to go up and down the stairs. Elevators are relatively confined environments, so if you do not wear a mask, when riding with multiple people, if there is a potentially infected person, it may lead to infection through droplet transmission and other means. It is recommended that when riding in an elevator, there should not be too many people if possible. You should ride alone or with fewer people. Be sure to wear a mask as standard when riding in an elevator and minimize contact with elevator buttons. If contact is necessary to do disinfection, after arriving home or to the office must pay attention to hand washing. Content source: Dr. You Lai
