(Fighting New Coronary Pneumonia) Xinjiang Centers for Disease Control: Gene sequencing shows that the epidemic was caused by exposure to the same source of infection
China News Service, Urumqi, August 4 (Reporter Sun Tingwen and Zhao Yamin) On the afternoon of August 4, the Press Office of the People's Government of Xinjiang Uygur Autonomous Region held the eighteenth press conference on epidemic prevention and control and answered reporters' questions.
In response to a reporter's question, "What has Xinjiang done in epidemiological investigations since the outbreak, and what progress has been made?". Cui Yan, director of Xinjiang Centers for Disease Control and Prevention, replied that from the current staged analysis of epidemiological investigations, the current epidemic in Xinjiang was manifested as a single source: by sequencing the genes of previous cases, the results showed that multiple test samples had the same sequence. It shows that the epidemic was caused by exposure to the same source of infection.

Cui Yan analyzed that the epidemic had three characteristics: First, it was "urgent." The epidemic developed rapidly in the early stage and the number of cases increased rapidly. After reaching a peak from July 26 to 28, it began to decline. The second is "gathering". The epidemic has shown strong regional and event clustering. So far, 99.3% of the cases have occurred in Urumqi. Changji and Kashgar each have 1 case and 2 cases imported or related to Urumqi. The third is "mild". The cases are mainly non-severe, with a high proportion of asymptomatic, mild and common types. In just two weeks on July 28, some cases have been discharged. So far, 42 cases have been cured and discharged, and 37 cases have been released from medical observation.
She said that after the outbreak of the epidemic, the State Council's joint prevention and control mechanism for the new crown pneumonia epidemic immediately sent an experienced team of circulation experts to Xinjiang to guide the work. Under the guidance of the national expert group, Xinjiang quickly integrated the autonomous region, city, district (county) three-level circulation team, coordinated the coordination of relevant departments and communities, and quickly cut off possible transmission channels through rapid, in-depth and detailed circulation work and strengthened The control measures for high-risk groups provide strong support for the effective and orderly implementation of epidemic prevention and control.
The first is to complete the epidemiological investigation of all confirmed cases, draw sequence diagrams and relationship diagrams to ensure that no one is missed, no clues are missed, and the daily flow adjustment work is cleared in time. Second, through epidemiological investigations, people in close contact were quickly identified, and concentrated medical observations were implemented. The third is to implement strict home control measures for the peripheral personnel of close contacts, and report their body temperature daily. The fourth is to carry out supplementary sampling and monitoring work in key areas and key places.
She reminded that citizens are expected to actively cooperate with the flow adjustment work and provide true and detailed information so that possible infected persons and risk points can be investigated and controlled as soon as possible. The behavior of concealing individual personnel's trajectory and illness is not only detrimental to their own treatment, but also extremely adversely affecting the prevention and control of the epidemic.
