The activity of the novel coronavirus can be significantly reduced after two hours of survival in vitro, and the virus can be effectively inactivated at 56°C for 30 minutes. The virus is also sensitive to ultraviolet light, and some chemicals, such as chlorinated disinfectants and peroxyacetic acid, are also effective in killing the virus.
