What are the sources of the two communication chains? Article 1 transmission chain means that the virus is highly likely to be infected through overseas articles, and the second article is spread through public goods and restaurants.
1, overseas articles. According to the description of the local infected person, the source does not exclude international mail, and the patient's infection belongs to mutant strain, which is highly similar to some strains isolated from North America and Singapore, while the infected person has not gone abroad, so it may be directly related to overseas items.
2. Public goods and meals. According to the description of local infected patients, they all have a common feature, that is, they have used public toilets. Secondly, there are some local infected people eating out. Therefore, it can also be inferred that the source of infection mainly comes from public goods and dining environment.
Therefore, the sources of the two communication chains are mainly spread through public goods and express mail, so people must pay special attention when sending and receiving express mail and using public goods.
How to put an end to the communication chain? There is no way to completely eliminate the transmission chain, because when no new drugs are developed, the development of COVID-19 can only be further confirmed through the cooperation of residents and regular nucleic acid screening. Secondly, if it is unnecessary, it is best not to go out, not to go to crowded places, and wearing a mask when going out can also play a protective role, thus greatly reducing the route of transmission.
Personal point of view. COVID-19 has spread for many years and has not been completely solved. During this period, people will naturally feel anxious and bored. However, when the corresponding drugs have not been developed internationally, we should still control the idea of going out to play, and this behavior is not only a respect for the country, but also a respect for our health.
