There is a certain risk of contact with public facilities such as staircase handrails and community equipment because the virus may attach to the surface of these public facilities and spread to others through contact. However, protection can be provided through measures such as not touching the staircase handrails or community equipment as much as possible, and wearing a mask throughout the entire process of going out. If you accidentally touch these public facilities, you should avoid touching your nose, mouth and eyes with your hands and wash your hands with hand sanitizer or soap when you get home. In addition, in order to prevent and control the epidemic, we still encourage people to stay home as much as possible, while increasing the disinfection of public facilities to reduce the probability of infection as much as possible.
