The epidemic situation in Xi, Shaanxi Province has spread to the whole country. Are the old couple in Shanghai the source of infection?

The epidemic situation in Xi 'an has not spread to all parts of the country, but it is really serious. Its related epidemic situation has spread to six provinces and seven cities 1 municipality directly under the central government, including 24 cases in Gansu. At least seven people in this tour group, which consists of people over 60 years old, were infected, and the activity track involved scenic spots and restaurants in several provinces.

The cases 1 and 2 confirmed by the tour group are from Shanghai, a couple. They flew from Shanghai to Gansu, and Xi 'an was the third stop. The old couple in Shanghai may not be the source of infection, and the source of infection of Xi 'an epidemic is still being traced.

Two: There is no local epidemic in Shanghai. Where did the old couple in Shanghai get infected and need to investigate the source of infection? There is no local epidemic in Shanghai. As of June 65438+1October 65438+September, there are five medium-risk areas in China, including two in Gansu, three in Inner Mongolia and no medium-high risk areas in Shanghai.

Cases 1 and 2 were tested for nucleic acid before leaving Shanghai. 1October 9th, 10, they flew from Shanghai to Xi 'an, and then transferred to Gansu. 1June13rd, the nucleic acid test results of both of them were negative. However, their nucleic acid detection in Gansu province was abnormal later, and the diagnosis time was June 65438+June 654381October+July.

In addition to cases 1 and 2, five other people in their tour group, as close contacts, also did nucleic acid tests and the results were positive.

At present, it can be determined that these seven people are in the same transmission chain. In addition, Yinchuan was diagnosed as 1 person, and the patient was a close contact of Shaanxi cases.

Case 1 2: The activity track of the old couple in Shanghai involves Gansu, Inner Mongolia and Xi 'an. It is still difficult to determine where they were infected, and it is necessary to wait for the follow-up viral genome sequencing and activity trajectory investigation to trace the source.

Three: the Xi epidemic spread to six provinces, and more than 23 people were infected. The Xi 'an epidemic was associated with many provinces in Inner Mongolia, and 24 people were infected, including 8 people in Xi 'an, Shaanxi, 6 people in Gansu, 5 people in Inner Mongolia, and Hunan, Guizhou, Beijing and Nanjing 1 person. Seven people in the tour group were infected, and their activities involved many scenic spots and public places in three provinces. There are six provinces related to the Xi 'an epidemic, so it is not easy to find out the source of infection.

In addition to screening infected people and preventing the epidemic from spreading to other provinces, Xi 'an also needs to trace the source of infection through big data screening and cut off the transmission channels of the virus. The outbreak of the epidemic is certainly traceable, but it does take time. After all, the seven members of this tour group have been to many places, which makes it more difficult to trace the source.

At present, the source of Xi 'an epidemic is still uncertain. We all hope that this epidemic can be controlled as soon as possible, and the source of infection can be found as soon as possible, so that Xi 'an can resume her usual life as soon as possible.

The source of the virus has not been determined, so it is recommended not to speculate. COVID-19 epidemic, the source of each disease is different. The root cause of the outbreak of its elite chess has not been clarified, and science is expected to solve the problem.
