Because the Huanan Seafood Market in Wuhan is the site of the outbreak of the new coronavirus in China. First of all, the eight recorded cases of new coronavirus patients had the same contact point with the Huanan Seafood Market, and the virus did indeed spread. It is carried by animals. The South China Seafood Market was not only a place selling seafood and seafood at first, but also sold some wild animals. Moreover, Wuhan is a transportation hub area. There are many passengers entering and leaving the station every day, so its infection probability It's relatively large.

At the beginning, the Wuhan government had a very negative attitude towards the prevention and control of the epidemic. It even refuted rumors that the new coronavirus was not transmitted from person to person, which led to people not paying much attention to the disease. Not many people wore masks on the streets. I went out on the eve of the Chinese New Year. On a bus full of passengers, only three people wore masks, which greatly increased the risk of infection. Moreover, this infectious disease is different from SARS in that it is very contagious. Maybe everyone is not wearing masks. I noticed that this infectious disease is so contagious, and the rate of infection is fast, and the base is larger, much larger than the SARS in 2004.

Furthermore, the Wuhan government did not take corresponding preventive and solution measures. It chose to conceal the report at the beginning, and made big mistakes, such as failing to announce the development of the disease to the outside world in a timely manner. It took a long time between the first case was reported and the outbreak on New Year's Eve. During this period, there were no new cases. However, after Academician Zhong Nanshan announced human-to-human transmission, the number of reported cases increased sharply the next day, led by a The number of people has not increased to several hundred. Could it be that the lack of timely notification resulted in many cases not receiving timely treatment?

Also, the symptoms of this virus are very similar to those of influenza. Many people think it is influenza when they get the virus, because respiratory symptoms are also typical symptoms of influenza. This also leads to many patients not receiving treatment in time and indirectly infecting other people. People, many cases are already seriously ill when they are discovered, which is also one of the reasons for the seriousness.
