As of November 4, the current round of the epidemic caused by the tour group has spread to 20 provinces and cities across the country, and the cumulative number of confirmed patients is nearly 800. In addition, there are some places where there are other transmission chains, such as Heihe, Ruili and so on. With the arrival of winter, many people are worried that the epidemic will start to get out of control again.
Just on November 5th, Academician Zhong Nanshan said at a meeting at Shenzhen Hospital that there were two unfavorable factors in winter epidemic prevention, but he also revealed a good news.
Disadvantage 1: Most of the cases are sporadic in the northwest, and it is difficult to track
From the words of Academician Zhong Nanshan, it is not difficult to understand that this round of epidemic has been distributed to the whole country from Gansu and Inner Mongolia, and the scope of transmission is extremely extensive, showing a clear multi-point distribution. The spread of this round of the epidemic is mainly related to travel, tourists from all over the country, will go to many cities and attractions, hotels, restaurants, etc., these places are more crowded. In addition, due to the relatively fast flow of passengers and the large number of people in contact, it is difficult to trace.
Moreover, the northwest region is vast, but some areas are economically underdeveloped or there are restrictions on conditions, which makes it impossible to implement temporary scenic spot control measures, and epidemic prevention is more difficult.
Take Ejina Banner as an example, it is a border crossing, so there is a risk of importation from abroad. However, the epidemic prevention capacity of scenic spots is limited, and at the same time, they are all over small hotels and restaurants, and once the nucleic acid testing intensity and level are not in place, it is easy for tourists to be infected with the new crown virus.
When large-scale tourists encounter the new crown virus, they will bring the virus from these places into densely populated cities, because some people receive news a few days after arriving home to report, in the process, they have already infected others, and then a new round of transmission in the local area has begun.
Disadvantage two: Winter has arrived, and people in the north have gathered more
This is indeed detrimental to epidemic prevention, with cold weather in winter and especially cold in the north. While temperature is not the condition that determines the survival of the coronavirus, studies have shown that they will exist longer in cold environments, which increases the risk of transmission. In addition, in winter, people have less activity, and immunity will be reduced, which also increases the risk of infection.
Some people in the north are used to "cats" spending the winter at home. In fact, this involves the problem of cluster epidemics. Once a person carries the virus but does not know it, then the people who gather together will most likely be all recruited, after all, familiar people get together to chat, play cards or eat together, which will lead to droplets or contact transmission.
Academician Zhong Nanshan revealed a small news that the epidemic can be controlled quickly
In addition to the unfavorable factors of winter epidemic prevention, Academician Zhong Nanshan also said that under China's strict epidemic prevention measures, the chain of infection will be found as soon as possible and the detection of close contacts will be strengthened, and the epidemic will not spread in large quantities and can be controlled quickly.
This has also brought confidence to many people that this round of epidemic will not be endless, as long as you do what you should do, this round of epidemic will soon end.
In daily life, we must do a good job in personal epidemic prevention and life epidemic prevention, such as timely injection of new crown vaccines and reinforced injections, frequent hand washing, wearing masks, enhancing immunity, ventilating more every day in winter, paying attention to keeping distance from others when going out, gathering less, paying attention to their own situation and family conditions in time after traveling, and reporting and nucleic acid testing in time if there is a problem.
All in all, winter is originally the high incidence season for respiratory diseases, and we are still facing pressure from overseas imports, and there may still be sporadic outbreaks after the end of this round of epidemics, or clusters of epidemics in local areas. The epidemic has not subsided, and everyone must pay attention to protecting themselves.
