Chlorhexidine, which is commonly used in daily life, has no effect in inactivating the novel coronavirus. In addition, bathing with hot water at 56℃, high temperature sauna, smearing the nasal cavity with small milled sesame oil, and drinking high level of white wine, etc. circulated on the Internet are not effective ways to inactivate novel coronavirus. Research on the novel coronavirus is still incomplete. Through the analysis of the available epidemiological data, researchers have conducted an in-depth study of the physicochemical properties of the novel coronavirus and found that the virus is sensitive to ultraviolet light and heat, and can be inactivated by heating at 56℃ for 30 minutes. In addition, lipid solvents such as ether, 75% ethanol, chlorine-containing disinfectants, peroxyacetic acid, and chloroform can effectively inactivate the virus.
