If you want to know whether COVID-19 will attach an e-mail package, you should first know the route of transmission in COVID-19.
1. Transmission route of COVID-19 ① Transmission through respiratory tract, mainly in the form of coughing, sneezing and droplets.
(2) Through contact and transmission, the things that the virus-infected people have touched are easily infected if they don't wash their hands in time to touch their nose, mouth and eyes after careless contact.
(3) Airborne transmission, where the virus stays and spreads for a long time is still contagious.
④ Fecal mouth infection
④ Environmental communication, in essence, is the communication of things, which is a new subject that needs to be solved urgently recently put forward by Academician Zhong Nanshan. Different from the second item, environmental transmission is an infection caused by contact with articles contaminated by viruses, which are generally imported in China at present.
Second, whether the express parcel carries a virus is unlikely to be infected by the virus during logistics and transportation. Because of the prevention and control of the whole process of goods packaging and transportation, there will be no infection under normal circumstances.
The only thing that needs attention is cold chain transportation, especially imported products. Experts say that the virus has a high survival rate in cold conditions. Assuming that the items are infected with the virus, even wearing a mask and washing your hands frequently can be avoided. It is worth noting that it is easy to form infection only by repeated contact with items with viruses. This situation tends to the so-called environmental transmission and material transmission.
However, it does not mean that contact will lead to infection. Virus prevention and control clearly points out that human-to-human transmission requires three conditions: ① serious pollution of articles; ② Long-term survival of virus in articles; ③ Failing to take timely protective measures when contacting infected articles.
Third, does the courier need to be disinfected? The virus spread attached to the courier belongs to the spread between people, and the formation of virus infection needs to meet the above three conditions at the same time. Therefore, there is no need to disinfect the courier, just take protective measures when taking the courier. Couriers are required to wear masks and gloves when receiving express delivery, which will also reduce the spread of the virus.
How to prevent it? Whether you will contact the courier or not, you should wear a mask and gloves when picking up the package. After picking up the parcel, put the courier bag into the box according to the garbage classification. Finally, take off your gloves and wash your hands in time. If possible, you can clean it with alcohol.
Of course, no matter how restless you are, you can also disinfect the courier with disinfectant first. It is always right to be cautious.
Human-to-human transmission generally occurs in the early stage of virus infection, but it has limited effect on epidemic spread. Whether it is human, environment or biological transmission, the most important medium is contact, and only contact can lead to infection. At present, COVID-19's main route of transmission in China is interpersonal communication.
