Confirmed cases in many places have a history of contact with overseas items International express delivery can not be received

Recently, the traceability of the confirmed case of Aomi Kerong released by Beijing, Shenzhen and other places shows that the case has been in contact with international express delivery, and the possibility of infection through imported items from abroad cannot be ruled out. In this regard, many people wonder why the international express delivery that has been disinfected is still tested positive for the new crown virus?

"It is difficult to isolate and culture live viruses in the environment, and a positive test generally refers to a positive nucleic acid test, at which time the virus may be alive or dead." According to Zhang Liubo, chief expert in disinfection at the Chinese Center for Disease Control and Prevention, disinfectants are generally effective against the new crown virus. However, disinfection can not completely eliminate the viral nucleic acid, because the disinfectant usually does not target the nucleic acid, the virus is dead but the nucleic acid is still there, so the express delivery that has been killed will sometimes be tested positive for the new crown virus nucleic acid.

Judging from the cases of cold chain or non-cold chain transmission of cold chain items in many provinces (cities) of the mainland in the past, the new crown virus can survive for a long time in low temperatures, so the risk of menstrual transmission in winter also increases. Does this mean that international express delivery can no longer be received?

"It is unscientific to simply think that receiving international couriers will infect the virus." Zhao Guojun, director of the Postal Development Research Center of Beijing University of Posts and Telecommunications, said, "After overseas express delivery enters China, express delivery companies have a set of strict killing links for the outer packaging of express delivery, so the presence of viruses on the outer packaging is also quite limited." ”

However, in order to strictly prevent the import of overseas epidemic diseases through delivery channels, the relevant departments have made proper arrangements. The State Post Bureau recently issued a notice requiring postal administration departments at all levels and postal express delivery enterprises to further improve their risk awareness and build a solid barrier for the prevention and control of the epidemic in international mail express. All postal express delivery enterprises should earnestly do a good job in disinfection and ventilation of international mail express processing places, and for imported international mail express mail, they should carry out disinfection of all aspects of the outer packaging one by one at the first time after entering the production processing link. Under the guidance of local epidemic prevention and control departments, it is necessary to clarify and implement the standing period after the disinfection of imported international mail express mail.

In the delivery process, how to do a good job in the "last mile" safety guarantee? In this regard, Bian Zuodong, deputy director of the Department of Market Supervision of the State Post Bureau, said that on the one hand, couriers are urged to implement the basic health protection requirements such as wearing masks, washing hands frequently, and not gathering, and holding certificates and holding health codes; on the other hand, actively organizing practitioners to complete the vaccination of new crown vaccines, at present, the vaccination rate of the whole industry has reached more than 98%. In addition, areas with conditions are encouraged to use smart express boxes to achieve contactless delivery. Remind the courier to take the initiative to remind the recipient to wear a mask, properly dispose of the outer packaging, disinfect the inner parts before using and other protective measures when delivering.

At present, the new crown pneumonia epidemic caused by the global Aomi Kerong mutant strain is still frequent and high. The State Post Bureau stressed that all postal express delivery enterprises should comprehensively assess the epidemic risk level of the source of imported mail express mail, the qualification of upstream business entities, the attributes of the delivered goods and other factors, and formulate a plan for the prevention and control of the epidemic in imported mail express mail from high-risk countries and regions in accordance with the relevant requirements of accurate prevention and control, promotion and control.

How is it safer for consumers to receive international couriers? "It is important for consumers to protect themselves throughout the process." Zhao Guojun believes that consumers should correctly wear disposable gloves and masks when receiving international express delivery, and while doing a good job of personal protection, after strictly killing the outer packaging of international express delivery, they cannot ignore the sterilization of internal items of express delivery. During the period of high incidence of epidemics abroad, it is recommended that consumers appropriately reduce the purchase of overseas goods, which is also a measure to strengthen self-protection.
