Last update date: 2020-06-15 22:50Beijing's recent new coronary pneumonia (COVID-19) epidemic has been repeated unexpectedly, and has brought many unsolved mysteries. Experts pointed out that the virus in the newly developed market is different from the new coronavirus popular in China, and it is more infectious than the southern China market in Wuhan, and it also has an impact on vaccine development.
On June 15, Gao Fu, director of the Chinese Center for Disease Control and Prevention, presided over a meeting and said that at present, the Chinese Center for Disease Control and Prevention has completed the determination and analysis of the whole genome sequence of virus in related sample cases. The preliminary conclusions have been reported and virus tracing is being actively carried out.
In order to support the needs of Beijing's epidemic prevention and control technology, on June 12, the Chinese Center for Disease Control and Prevention quickly launched the P3 laboratory in the southern part of the virus disease clinic to expand its detection capacity. On June 13, the complete genome sequence determination and analysis of the virus of the relevant case samples was completed, and the preliminary conclusions have been reported and the virus traceability has been carried out.
At present, based on laboratory test results, authoritative domestic experts in China have initially determined that the virus may come from Europe or even the Americas.
On the afternoon of the 15th, Yang Zhanqiu, professor of the Institute of Virology, Wuhan University, said in an interview with the media that 79 cases were diagnosed in Beijing Xinfadi within 4 days, indicating that the infectivity of the new crown virus found in Beijing Xinfadi may be stronger than that of Wuhan South China Seafood Market .
He also believes that if the virus is imported from overseas through cold and fresh biological products, the content contained in the "foreign defense import" will be expanded to the customs quarantine of these products; in addition, the different virus types will also affect the development of vaccines. , Yang Zhanqiu believes that this increases the difficulty of vaccine development.
After no new confirmed cases in the past two months, Beijing had new local cases on June 11, followed by several new days.
According to official information, most of the new cases in Beijing are related to the wholesale market in the new location of Fengtai District in Beijing. Facing the current grim situation, Beijing Fengtai has launched a wartime mechanism and sealed off the wholesale market in Xinfadi.
In addition, local cases in Beijing have now spread across provinces. On June 13, two asymptomatic infections in Shenyang, Liaoning Province were converted to confirmed cases and were close contacts of confirmed cases in Beijing. Disease control centers in Dalian, Liaoning, Luliang, Shanxi, Daqing, Heilongjiang, Dandong, Liaoning, Harbin, Heilongjiang and other places issued a reminder: If not necessary, citizens should not go to Beijing in the near future.
