"The mechanism of disinfection of express packaging is to destroy the protein of the virus, make it denatured and lose the ability of transmission, not to decompose the nucleic acid - so the sterilized express can still detect the nucleic acid virus, but the virus at this time has no ability to infect." At the press conference on epidemic prevention and control in Zhejiang Province on March 6, Lu Ye, deputy director of the Institute of environmental health of the Provincial Center for Disease Control and prevention, said. He said, for the disinfection of express, according to the existing scientific evidence, medical disinfectants which meet the medical level have inactivation effect on which COVID-19 variant strains. COVID-19 is composed of protein nucleic acid. The way of chemical disinfection is mainly to inactivate the virus, the mechanism is to destroy the viral protein, and make its degeneration lose the ability to transmit. It does not decompose nucleic acids. "So that's why sometimes when we disinfect the external packaging, we can still detect nucleic acid fragments, but at this time, the virus has no infectious ability." He said that for the public, the selection of disinfection products mainly depends on whether the outer package is marked with the words "hygiene license of disinfection products". Secondly, if the mark on the product manual is applicable to the surface disinfection of environmental objects, the surface disinfection of environmental objects can be carried out on the stacked express and express and its place. Lu Ye reminded that we should not forget that unpacking tools and transfer tools, such as carts and pens and mobile phones used in the signing process also need to be disinfected. "Collecting express mail seems to be a small matter, but there are many details related to each of us. I hope you can start with the details, everyone can do a good job in epidemic prevention and prevent all possible risk factors." (Xinhua News Agency)
