Through epidemiological investigation in Xinjiang, no cases, case contacts or high-risk groups were found, so the infection route of cases became a famous population. The only thing that can be determined now is that the real cause of the epidemic in Xinjiang was caused by a gathering activity. The case outbreaks were mainly concentrated in Tianshan District, Urumqi, Xinjiang.
We know that Xinjiang's land border has exceeded 5,000 kilometers, bordering many countries, such as Mongolia, Russia, Afghanistan and India.
In this epidemic, it is impossible to determine whether the virus originated in Beijing or abroad, whether it was introduced from the mainland, or whether it was due to geographical factors, ethnic factors and migration of foreign population. Some people think that the virus may be introduced by outsiders or things. Since Xinjiang has been located in the northwest of China since ancient times, in the hinterland of Eurasia, it was an important passage to block the Silk Road in history, and now it is also the only place for the second Eurasian continental bridge. Because Xinjiang has a long border, more than 5 kilometers, and borders with 8 countries, it is more likely that the epidemic will be imported abroad.
In addition, Xinjiang has been a multi-ethnic region since ancient times, bordering other countries, and there have been unexplained pneumonia in Kazakhstan, or viruses carried by people traveling from all over the world in Tianshan Mountains. Everything is unknown. Planting, the cunning of COVID-19 and the gap between the public and mainland health forces have led to all these epidemics.
Due to the complexity of virus traceability, the origin of virus in COVID-19 needs big data comparison or epidemiological investigation, including the trajectory of infected people and sequencing of biological whole genes. Only by analyzing these aspects can we determine the source of infection.
Although the source of COVID-19 epidemic was not found, the epidemic was concentrated in Urumqi, which was in wartime. The residential areas in Urumqi have also been closed, and all people who are in close contact with the virus are concentrated and isolated, and nucleic acid testing is carried out for key people. Now the leadership of Ulumu has conducted a strict thorough investigation to ensure that there are no omissions and no dead ends.
In the early days of the outbreak in Xinjiang, many cases have been found to be ordinary or mild. The number of cases is still increasing, but it is not out of control. Infected people and high-risk groups have been isolated. Through these measures, the source of infection was cut off from the source, and the previous cases were infected, not later, so there is no need to panic. Although it will take some time for the epidemic to end, there will be no large-scale epidemic in Xinjiang.
