Epidemic transmission chain
has not been completely cut off
It is also possible to be infected if it does not leave the community
Come and take a look at
At present, the domestic epidemic prevention and control virus transmission chain has not been completely cut off, and the risk of virus hiding and spreading in the community is still high. Hanzhong University of Science and Technology Tongji Medical College Professor Wei Sheng said that the community is the basic unit of society and the basic space for people's production and life. Most community members in Wuhan are highly concentrated. Once a positive infection occurs, especially the asymptomatic infection of , , without knowing it, it is easy to cause hidden transmission risks in multiple chains. Therefore, it is particularly important to do a good job in community epidemic prevention and control.

According to public reports, new infections in a certain place in China have been concentrated in communities with densely populated populations. "This type of environment has an amplifier effect on the spread of the epidemic, and the epidemic is very prone to rapid and concealed transmission." Wei Sheng further stated that the Omickron BA.5.2 mutant strain that is prevalent in this round of epidemic has strong transmission power and strong concealment, and the transmission method is mainly transmitted to others through respiratory droplet transmission and contact transmission.
Community transmission risk is mainly reflected in two aspects:
First, the transmission chain caused by the gathering activities of indoor personnel such as chess and card rooms, community activity rooms, etc. Potential infected people in these places may release the virus into the air and form droplets. People around them cause infection by inhaling this virus-containing droplet;
Second, if potential infected people go in and out of key places such as garbage dumping points, public toilets, elevators, etc., may cause new coronavirus pollution in the environment, and infection may also be possible through contact.
Due to the existence of a detection window period, it is difficult to detect all asymptomatic infected people at one time by using nucleic acid detection and antigen detection, making it difficult to prevent transmission caused by asymptomatic infected people hiding in the community.
Strengthen reporting Strengthening nucleic acid Strengthening protection
In view of the high risk of Omickron's hidden transmission in the community, Wei Sheng pointed out: "In order to avoid the hidden transmission of the virus in the community, it is necessary to obtain the understanding and full cooperation of community residents. Specifically, there are three points: Strengthen reporting, strengthening nucleic acid, and strengthening protection. "
First, strengthening reporting. Citizens should have a sense of epidemic risk and pay close attention to the epidemic information released by authoritative departments. If they have a history of traveling in medium and high-risk areas in China within the past 14 days, or find people who overlap with the announced activities of positive COVID-19 infections and accompanying people at the same time, they should report the visit time and location to their communities as soon as possible, and first consciously carry out home health monitoring to minimize social activities and prevent the epidemic from spreading to the society. When entering and leaving the community, you must scan the health code, check the itinerary, check the body temperature, and wear a mask.
followed by strengthening nucleic acid testing. Because Omickron currently mutates quickly and spreads quickly, in order to detect new coronavirus infected people hidden in the community in a timely manner in the early stage, prevent the spread of the virus, and avoid infecting more people, community residents should actively cooperate with the local nucleic acid testing policies and actively participate in normalized nucleic acid testing. All tests should be tested, which can help us detect and deal with the epidemic early.
Furthermore, take good protection. Wei Sheng emphasized that protection should be comprehensive, not only limited to common protective measures such as wearing masks and frequent hand washing, but also includes that citizens in various risk areas should implement targeted protection requirements."Citizens in high-risk areas should adopt 'no home leave and door-to-door service'; citizens in medium-risk areas should "do not leave the area, and take things off peaks"; citizens in low-risk areas should also have the risk awareness of 'low risk does not equal zero risk', so as not to gather, not to gather, not to gather, not to visit each other, reduce close contact with others, wear masks when going out for activities or going downstairs for walks or going downstairs for nucleic acid, and try to keep a certain distance from others when entering public places or taking public transportation." Wei Sheng said.
In the face of the epidemic, everyone is both a community of shared future and a community of responsibility. As long as everyone is united, united as one, and continues to cooperate in the implementation of various epidemic prevention measures, they will surely usher in the dawn of victory in the fight against the epidemic as soon as possible.
