It has been found that novel coronavirus is sensitive to UV light and heat, and that lipid solvents such as 75% alcohol, ether, peroxyacetic acid, chlorinated disinfectants and chloroform can effectively inactivate novel coronavirus at 56°C for 30 minutes. However, chlorhexidine does not inactivate the virus effectively and disinfectants containing chlorhexidine should be avoided. In addition, the virus cannot exist and reproduce independently, and it cannot survive for a long time after leaving the living body, much less reproduce. It is advisable to ventilate the room, pay attention to cleaning and disinfection, reduce crowded places, and wear a mask to prevent infection.
