(Fighting New Coronary Pneumonia) Beijing Disease Control: The previous cases of this round of the epidemic are in the same transmission chain as the Nanjing epidemic

  China News Agency, Beijing, August 4 (Reporter Chen Hang) Recently, Beijing has discovered multiple cases of infections caused by mutant delta strains of the epidemic outside Beijing.

Beijing conducted whole-genome sequencing of samples from the early stage of the epidemic, and the results showed that it is highly homologous to the whole genome of the recent Nanjing epidemic virus and belongs to the same transmission chain.

  This is what the reporter learned from a press conference on the prevention and control of the new crown pneumonia epidemic in Beijing on the 4th.

  Pang Xinghuo, deputy director of the Beijing Municipal Center for Disease Control and Prevention, stated that between 0:00 and 12:00 on August 4, there were three newly confirmed cases in Beijing related to the epidemic situation outside Beijing, all of whom were close contacts of the confirmed cases announced on August 1.

Among them, 2 were relatives of the confirmed case, with a travel history in Zhangjiajie City, Hunan Province, and 1 was a close contact of the confirmed case on the same flight.

  She mentioned that 50 close contacts of the confirmed cases were initially determined, and close contacts at other risk points are being verified.

  Since July 28, Beijing has accumulatively added 8 local confirmed cases related to the epidemic outside Beijing and 1 asymptomatic infection.

Pang Xinghuo said that the whole genome sequence of the samples of this round of pre-epidemic cases by the Beijing Centers for Disease Control and Prevention laboratory showed that it is highly homologous to the whole genome of the recent Nanjing epidemic virus and belongs to the same transmission chain.

  "In view of the high infectivity and spreading power of the delta mutant strain, the import risk and the pressure on prevention and control faced by Beijing continue to increase." The Lehuojiayuan community in Yancun Town is designated as a medium-risk area.

Up to now, there are 2 medium-risk areas in Beijing, and other areas in the city are low-risk areas.

  Pang Xinghuo reminds the public that if there is an overlap with the trajectory of confirmed cases, or those who have recently lived in high-risk areas or have close contacts with people in high-risk areas, they must report immediately and cooperate with nucleic acid testing, isolation and observation, etc. Prevention and control measures.

  In addition, Beijing has identified medium-risk areas and community streets and units where confirmed cases are reported are not allowed to leave Beijing in principle. Those who are still traveling outside Beijing are advised to end their trips as soon as possible and pay close attention to the progress of the local epidemic and prevention and control measures, trains and trains. Changes in flight ticket sales, take personal protection.

  “Wearing a mask, washing hands frequently, killing frequently, maintaining ventilation, and controlling distances are still the simplest and most effective protective measures.” Qi Jinli, deputy head of the steering group of the Beijing New Coronary Pneumonia Epidemic Prevention and Control Work Leading Group, said that the weather is hot now. Although wearing a mask is not so comfortable, safety is more important.
