On February 26, the Joint prevention and control mechanism of The State Council held a press conference to introduce the epidemic prevention and control and vaccination work.Mi Feng, spokesperson of the NHC and deputy director of the Publicity Department of the NHC, said that as of February 25, a total of 3.14 billion novel coronavirus vaccine doses had been reported nationwide, with a total of 1.234 billion people having completed the whole course of vaccination.In the past week, 15 provinces have reported new locally confirmed cases, said Mi Feng, spokesman for the NHC and deputy director of the publicity department.We need to respond quickly, seize the critical “window period” in the early stage of the response to the cluster of cases, resolutely take all prevention and control measures, and realize the “zero social gatherings” as soon as possible.The epidemic prevention and control measures should be implemented in key groups, places and links to minimize the risk of the spread of the epidemic.Wu Liangyou, deputy director of the DISEASE control and Prevention Bureau of the NHC, said that the recent domestic epidemic shows a large number of spots, a wide range of frequent, delta and Omicron variant strains superimposed epidemic characteristics.Wu Liangyou, deputy director of the Disease Control and Prevention Bureau of the National Health Commission, said that the cases in Beijing, Tianjin, Shanxi, Shanghai, Shandong, Xiamen, Fujian and Jixi, Heilongjiang were all isolated or closed-loop management personnel, and the risk of further spread of the epidemic is low.The newly infected people in Suzhou, Jiangsu province, are mainly from those under control. The epidemic is on a downward trend, and the risk of community transmission is gradually decreasing. The local authorities are continuously strengthening the management of the containment and control areas.The number of cases in Huludao, Liaoning province, has increased recently, which requires vigilance against the rebound and further spread of the epidemic.The source of infection is still under investigation, and there is a risk of spread of the epidemic. Local authorities are further checking the movements of infected people and strengthening screening and control of those at risk.The newly confirmed cases in Lincang, Yunnan province are concentrated in a local middle school. All teachers and students need to be transported and isolated as soon as possible, and nucleic acid screening in key areas should be accelerated to prevent further spread of the epidemic in schools and communities.Shenzhen, Guangdong has a wide range of epidemic sites and complex transmission chains, with high risk of community transmission and spillover. The newly infected people in Dongguan are mainly distributed in an industrial park with a high population density. Relevant cities in Guangdong are strengthening screening and control of those at risk, accelerating the push of information for assistance, and preventing further spread of the epidemic.Chengdu in Sichuan province and Fangchenggang in Guangxi province are at risk of further spread of the virus. Local authorities are speeding up screening and control of those at risk to prevent spilovers.The outbreak in Wuhan, Hubei province has spread to Beijing, Shandong, Hebei, Shanghai and other provinces (cities). Local authorities are working to track down and control those at risk and speed up screening of those who spilled over to prevent further spread of the epidemic.The epidemic in Hohhot, Inner Mongolia, is still at a high plateau, but the risk of community transmission and spread has decreased. Local authorities are making all-out efforts to strengthen the handling of community screening cases and the control of key areas such as containment areas, and further implement prevention and control measures.Wu liangyou said that from China’s epidemic prevention and control experience, the current prevention and control measures against the omicron variant strain are effective, the key is to implement the “four early principle”, consolidate the “four party responsibility”.The NHC will guide areas affected by the epidemic, speed up nucleic acid screening in key areas, strengthen epidemic screening, timely standardize the isolation and control of people at risk, and implement detailed prevention and control measures to ensure the overall stability of the epidemic situation.
