Many people wonder why there are so many imported cases in China, but there are no cases. The reason is actually very simple. By 24: 00 on September 16, there were 14 1 confirmed cases in 3/KLOC-0 provinces and Xinjiang Production and Construction Corps, including severe cases 1 case. During the epidemic in COVID-19, 80,448 cases were cured and discharged, 4,634 cases died, and 85,223 cases were diagnosed, suspected 1 case. At present, 6496 close contacts are under medical observation.
The domestic epidemic has long been effectively controlled. On the other hand, many countries in the world are still plagued by pneumonia. For example, according to the real-time statistics of the World Health Organization, as of June 16, Beijing time, there were more than 29.73 million confirmed cases and 939,000 deaths in COVID-19. Among them, the cumulative number of confirmed cases in COVID-19 ranks first in the world, with nearly 6.79 million infected people and more than 200,000 deaths. Except the United States, the cumulative number of confirmed cases in India, Brazil and Russia has exceeded 1 10,000. France, Britain, Germany, Iran, Italy and other countries have confirmed more than 200,000 cases. Although the global city closure policy some time ago has reduced the spread of COVID-19. However, with the lifting of the ban, going to school and returning to work provided a good way for COVID-19 to spread.
Because the incubation period of COVID-19 is relatively short, it is difficult for people to judge when there are no symptoms. Especially after the domestic epidemic has been basically controlled, in the face of such a serious epidemic abroad, many people who have gone abroad before want to return home for their own safety. Besides these people, people from other countries who come to China for business or work will also come to China from their own countries. Because these people have come into contact with many people abroad, they simply don't know whether there are COVID-19 patients among the people they have come into contact with, let alone whether they have been infected after coming into contact with other people.
Especially now, the pneumonia virus has changed to some extent compared with the beginning, and both the symptoms and the incubation period are very different from before. Many people have come from abroad, so there is no problem in checking before boarding. However, he got off the plane after entering the country, and it took several days for the problem to appear. The reason why overseas input is so difficult to control. After all, no one knows if there is any problem with this person coming from abroad, but it is no problem through testing, and then it is isolated for 15 days to judge.
