The new coronavirus cannot survive in air alone, but needs to rely on liquid, medium, and the new coronavirus is very sensitive to sunlight and ultraviolet light as well as air quality, and it does not survive for a long time in the outside environment, and the higher the temperature, the more difficult it is for the virus to survive. If the temperature is low, the virus will survive longer in vitro. The home environment can be disinfected with the appropriate concentration of 84 disinfectant, disinfecting the floor and objects that the patient has touched, and ventilating in a timely manner.
