There are more than 654.38+10,000 local infected people in Shanghai. Why did this epidemic spread widely in Shanghai?

At present, the two areas with the most serious epidemic situation are Shanghai and Jilin. In particular, the epidemic in Shanghai has spread widely. The number of local infected people exceeded 654.38+10,000, including19,660 newly infected people on April 6. The public cannot help asking a question. There is a precedent for Wuhan to fight the epidemic. Why did this epidemic spread in Shanghai?

I think the first reason is that this wave of popular COVID-19 is mainly a mutant of Omicron. This mutant virus has a strong concealment in the early stage of development, and it spreads quickly, and most people are asymptomatic. In the past, people would go to the hospital after they had symptoms of fever and cough, so that doctors could find it in time and control it as soon as possible. But now many infected people know that they are infected cases only after nucleic acid testing, but they have been active in public places for several days, which undoubtedly increases the number of close contacts, increases the risk of infection in COVID-19, and brings great difficulties to the accurate prevention and control of the epidemic. ?

? The second reason is that Shanghai is an international metropolis with a population of more than 25 million and a complex population. People from all over the country and many friends from abroad have brought great difficulties to the epidemic prevention work. In addition, there are many international flights and cargo planes, which undertake most of China's foreign trade. The epidemic situation abroad is relatively serious, and Shanghai is under great pressure to prevent and control foreign imports.

? The third reason is that people's thoughts are slack. Most people in China have been vaccinated with COVID-19 vaccine, so residents may relax their vigilance, pay insufficient attention to protection, and do not do enough protection, such as not wearing masks when traveling. In addition, China's epidemic prevention and control has also won before, and has always insisted on dynamic clearing. People began to relax, just in time for spring, the weather turned warmer, people wanted to restore their previous lives and began to travel frequently.

The Wuhan epidemic was our first contact with COVID-19. Without any experience, only by relying on scientific epidemic prevention and integrated traditional Chinese and western medicine treatment can we win the battle against the epidemic. Therefore, under the premise of having so much valuable experience, I believe that with our joint efforts, the epidemic will eventually pass, and as long as we persist, we will definitely fight this epidemic defense.
