(Fighting New Coronary Pneumonia) 44 Key Transmission Chain Cases of Hebei Outbreak, 27 Viral Gene Sequencing Completed
China News Service, Shijiazhuang, January 12 (translated by reporter Wang Tian) China News Service reporter learned from Hebei Provincial Center for Disease Control and Prevention (hereinafter referred to as Hebei Provincial Center for Disease Control and Prevention) on the 12th that as of the morning of the same day, the center had been The confirmed cases of new coronary pneumonia reported in Hebei Province and the 44 cases of key transmission chain cases among asymptomatic infections imported from Hebei Province reported in Xinjiang. Viral gene sequencing has been launched. Among them, 27 viral gene sequencing reports have been completed, all of which belong to European new coronavirus genes Branch of evolution.
According to Qi Shunxiang, director of the Viral Disease Prevention and Control Institute of the Hebei Provincial Center for Disease Control and Prevention, on the evening of January 2, after the Second Affiliated Hospital of Hebei Medical University and the Shijiazhuang Center for Disease Control and Prevention successively confirmed, a specimen of a local confirmed new coronary pneumonia patient in Hebei Sent to Hebei Provincial Center for Disease Control and Prevention.
The Hebei Provincial Center for Disease Control and Prevention immediately began to sequence the virus gene of the case and reported it to the National Center for Disease Control and Prevention.
Qi Shunxiang said that the virus gene sequencing work takes 48 hours. After two samples were used in the two factories’ reagent nucleic acid tests were confirmed to be positive, the genome sequence of the first confirmed patient in Shijiazhuang was carried out, and the results were tested with the National Center for Disease Control and Prevention. By comparison, it is found that they are highly consistent with the virus gene sequences reported in Europe.
According to Qi Shunxiang, the Hebei Provincial Center for Disease Control and Prevention dispatched an emergency inspection team overnight to Zhengding International Airport to conduct inspections on the T2 terminal, logistics vehicles in the airport, flight cargo, elevator handrails, toilets, etc., as well as the food factory’s refrigerated warehouse and a nearby hotel. Carry out environmental sampling work with patients’ families and other places.
After testing the 227 environmental samples submitted for inspection, it was found that the home environment of individual patients was positive, which should be caused by the virus pollution discharged by the patients.
Qi Shunxiang believes that after investigation, the tracing of the Hebei epidemic is based on the transmission of asymptomatic infections from overseas returnees, and the other is the transmission of imported goods and cold chain foods.
Currently, the Hebei Provincial Center for Disease Control and Prevention is launching genetic tracing work on these two lines.
According to Qi Shunxiang, as of the morning of the 12th, the Hebei Provincial Center for Disease Control and Prevention and the Chinese Center for Disease Control and Prevention have jointly carried out all 44 key transmission chain cases related to the Hebei epidemic, including one case of asymptomatic infection reported from Hebei. Viral gene sequencing work, of which 27 viral gene sequencing reports have been completed, all belong to the evolutionary branch of the European new coronavirus gene.
