The novel coronavirus is more fragile than the hepatitis B virus and is very easy to kill. Its physicochemical properties are cognitively derived from SARS and MERS viruses. This novel coronavirus is very sensitive to UV light and high heat, and can be inactivated by a 56°C water bath for 30 minutes, while hepatitis B virus requires high pressure steam for more than 10 minutes to inactivate. The new coronavirus is less resistant to heat and heat. Not only that, ether, 75% ethanol that is medical alcohol can play a role in the inactivation of the virus. However, it should be noted that too high a concentration of ethanol may form an alcoholic film on the surface of the virus, reducing the inactivation effect. Other disinfectants, including chlorinated disinfectants such as 84 disinfectant, peracetic acid, chloroform and other fat-soluble solvents can effectively inactivate viruses. It should be reminded that commonly used broad-spectrum antimicrobial virucidal agents are not effective in inactivating viruses. Content source: Dr. You Lai
