Elevators used by patients with novel coronavirus pneumonia are best disinfected in health care facilities or in the community to avoid infecting other people who ride them. General elevator disinfection can be done with peroxyacetic acid or 84 disinfectant, but both have irritating odors and need to be placed for a period of time after disinfection before allowing others to use them; otherwise, if ventilation is poor, there is a high risk of infecting others or causing respiratory discomfort due to inhalation of the disinfectant. Disinfection should be done under good ventilation as much as possible. Also, for elevator buttons, if the patient has had contact with them, they can be disinfected with 75% alcohol. These buttons may involve electrical circuits and have a corrosive effect if 84 disinfectant or peracetic acid is used, which may cause the buttons to be insensitive or malfunction when used. If there is still patient vomit or excrement in the elevator, cover it with a more concentrated chlorinated disinfectant to disinfect. Content source: Dr. You Lai
