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. Shenzhen 12345 government service convenience hotline staff told the Zhongxin Jingwei reporter on the 19th that during this time received overseas courier, the health code may turn yellow, but there is no more information and unified regulations.
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?
Zhang Liubo, chief expert of sterilization at the Chinese Center for Disease Control and Prevention, will teach you:
1Why is the express delivery that has been killed still tested positive for the new crown virus?
Isolation and culture of live viruses in the environment is difficult, and a positive test generally refers to a positive nucleic acid test. At this point, the virus may be alive or dead.
Disinfectants are generally effective against covid-19, but we cannot completely eliminate viral nucleic acids through disinfection. Because disinfectants are usually not aimed at nucleic acids, 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 nucleic acid of the new crown virus.
2What should I pay attention to when receiving international courier?
Expert tip: try to use international express as little as possible, and do not use international express delivery when it is not necessary or urgently needed.
At present, the new crown epidemic situation abroad is high, and the domestic situation is in a dynamic zero situation, and the epidemic situation at home and abroad is very different.
The possibility of contamination of items entering the country from abroad exists, and people exposed to the virus may be infected.
This requires courier companies to carry out proper disinfection when sorting to ensure that the outer packaging surface is not contaminated by live viruses. On the other hand, it also prompts us to take certain disinfection and protective measures to ensure safety when contacting express delivery.
3How to receive international express delivery safely under the normalization of the epidemic?
First, leave the packaging open for a while, and the safety of epidemic prevention will increase.
Second, try to avoid direct contact between people and people, and it is recommended to put the goods in the express locker.
Third, wear a mask when taking the courier, preferably gloves. If gloves are not available, hand disinfection should be performed with hand disinfectant after treatment.
Fourth, after getting the courier, you can use disinfectant to spray or wipe the surface of the courier to do a disinfection in all directions. The dose of disinfectant should be used correctly, each side should be completely wet, and a thin layer of water mist can be seen on the surface, and disinfection is in place. A few random sprays of disinfection are ineffective.
Regarding the choice of disinfectants: In addition to chlorhexidine disinfectants, it can be said that all disinfectants are effective, and there is no need to deliberately choose a disinfectant that is effective against the new crown virus.
Fifth, suppose there is a layer of items in the bag, you can disinfect it again, as above.
Sixth, after touching the items, use hand sanitizer to disinfect your hands or wash your hands according to the six-step method with running water.
Finally, the outer packaging that has been sprayed with disinfectant can be disposed of as ordinary garbage. If it is determined that the outer packaging is contaminated with the new crown virus, it needs to be treated as medical waste.
4How does the courier brother do a good job of personal protection?
First, masks are required throughout the entire contact item.
Second, it is best to wear gloves to handle items and pay attention to hand hygiene.
Third, timely vaccination against the new crown virus.
The courier brother has more opportunities to contact the goods, so it is necessary to strengthen health monitoring, always pay attention to their physical condition, and stop the relevant work in time if there is discomfort, and diagnose and treat as soon as possible.
Expert reminder: for items from foreign express delivery, in addition to paying attention to the outer packaging, but also need to pay attention to the pollution problem of the goods themselves, if the purchased items belong to manual production, the risk of contamination may be higher.
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.
