This round of epidemic in Langfang involves 22 schools. Where is the source of the local epidemic?

At present, Hebei has been identified as a high-risk area, and the whole province has entered a wartime state. I did survive at the beginning of the year, but not at the end of the year. For the source of the epidemic, we immediately carried out measures such as mobile investigation and isolation control, and introduced preliminary investigations from abroad. In order to prevent the spread of 20 19 coronavirus disease, personnel control and nucleic acid detection should be done well to prevent coronavirus pneumonia-19 from spreading and spreading to more people. Since the end of the Wuhan epidemic, the overall epidemic prevention work in northwest China has been done well, and the overall epidemic prevention effect is also very good.

There is basically no large-scale outbreak. However, due to a tour group in Ejina Banner, Inner Mongolia, the prevention and control of COVID-19 in many northwest areas has been strengthened again. The press conference was informed that there was no obvious turning point in the epidemic, the risk of proliferation still existed, and the traceability work was still in progress. By comparing the gene sequencing of Xingtai case samples, experts found that the virus was different from the virus in China gene bank, which may rule out that the source of the virus outbreak was in China.

This case belongs to a European family branch. It is speculated that the virus of this epidemic came from abroad. This fully shows that the cause of this outbreak is still the source of imported virus, which provides an important reference for us to do a good job in the follow-up epidemic prevention and control measures. Recently, many people who tested positive in COVID-19 passed through northwest, central and north China by EMU trains. Therefore, in the event of an epidemic, it is actually very dangerous to take the train and other means of transportation, because the train takes a long time and it is difficult to ensure that everyone always wears a mask.

Before taking the high-speed train, I found that many people would eat and drink on the road, and it was unrealistic to wear a mask for a long time. Coronavirus occurred on 20 19, so once one or two people just got on the train of coronavirus pneumonia-19, others were particularly dangerous on the train or on the train. The source of the epidemic is guo zhuang cun, which is only 10 minutes' drive from zhengding international airport. Zhengding international airport is one of the designated entry points for international flights. The flight ca9 10 runs between Moscow and Shijiazhuang. It can be preliminarily judged that it was passed on to the airport staff by outsiders in Moscow, Russia. The reasons for the spread of the epidemic are as follows: First, the winter weather is conducive to the spread of respiratory infectious diseases, and social activities such as weddings and funerals of villagers in Hebei epidemic areas are very intensive, which intensifies the spread of the epidemic. Second, lack of discovery ability. There are still weak links in the ability of disease transmission and detection in rural grassroots. It had spread for some time before it was discovered in rural areas. So it led to the sudden outbreak of Hebei epidemic.
