There is a risk of infection when riding in an elevator, but it can be prevented by some protective measures. The new coronavirus is mainly spread through droplet transmission and contact transmission, and elevators are confined and small environments, so if you ride in an elevator with a carrier, you may be infected by droplets from his or her coughing, sneezing, or talking. If the droplets fall on the buttons or elevator walls, they may be spread by contact. For this case, you can wear a mask to ride in the elevator, do not directly touch the elevator buttons or walls with your hands, you can use disposable gloves or paper towels for protection, and you need to wash your hand hygiene first after you arrive home to reduce the possibility of infection.
