The new coronavirus is more fragile and easier to inactivate than other known viruses. In the fifth edition of the diagnostic and treatment guidelines, it is clearly stated that the physicochemical properties of the new coronavirus, although derived from the SARS coronavirus and the MERS coronavirus, are relatively the same, and that the virus is very sensitive to ultraviolet light and heat, and that it can be inactivated in 30 minutes at 56 degrees Celsius. It has been reported that if the new coronavirus can be completely inactivated in boiling water at 100 ℃ for 1 minute under standard atmospheric pressure, which is much worse than the familiar hepatitis B virus vitality, and the hepatitis B virus may be inactivated in high pressure steam at about 130 ℃ for 10 minutes. In addition, ether, 75% ethanol that is medical alcohol, chlorine disinfectants such as 84 disinfectant, peroxyacetic acid, chloroform and other fat solvents are very effective on the new coronavirus inactivation of the virus, but has a strong broad-spectrum antibacterial bacteriostatic effect of chlorhexidine can not be effective in inactivation of the virus. Therefore, the new coronavirus is both afraid of alcohol and intolerant of high temperature. People can take corresponding countermeasures, such as wiping with 75% alcohol, ventilating the room in time, or sterilizing takeaway food with high temperature, and if you are worried about the possibility of infection by the new coronavirus, high-temperature disinfection can completely inactivate the new coronavirus.
