Yantai, Shandong added a new local infected person “2+34”, the first domestic evolution branch of Omicron BA.2.3

China Youth Daily client, Jinan, April 25th (China Youth Daily, China Youth Daily reporter Xing Ting) According to the latest report of the epidemic prevention and control press conference held by the Yantai Municipal Government of Shandong Province this morning, April From 0:00 to 24:00 on the 24th, there were 36 new infections in the city, including 2 confirmed cases, all of which were common types, and 34 asymptomatic infections, all of which have been transferred to designated hospitals. Up to now, the city has completed the gene sequencing analysis of 16 local cases in 4 districts and cities, which belong to the same transmission chain. The genotype of the case is Omicron BA.2.3 evolutionary branch, which is the first occurrence in China.

According to reports, among the newly infected people, there were 2 confirmed cases and 22 asymptomatic infections in Zhaoyuan City. All were detected in centralized quarantine personnel. Among the 9 cases in Penglai District, 3 cases were detected in the centralized isolation personnel, of which 2 cases were close contacts of asymptomatic infected persons reported on the 23rd, and 1 case was from Xiwutongkuang Village, Jinling Town, Zhaoyuan City to Penglai; 6 cases were found in the nucleic acid screening of risk personnel in key areas. There are 2 cases in Zhifu District, 1 case was detected in the centralized isolation personnel, and 1 case was found in the nucleic acid screening of risk personnel in key areas, all of whom were asymptomatic infected people in Zhaoyuan City at the same time. One case in Laizhou City was detected in the centralized isolation personnel, and it was a co-resident of the asymptomatic infection reported on the 23rd.

At present, the provincial, municipal, and county-level transfer teams are working hard day and night to check the trajectory of positive people and important related personnel. A total of 1,700 people in close contact and 3,179 people in sub-close contact have been investigated in the city, and all isolation control measures have been implemented.

It is understood that Yantai City has established a team of experts including traditional Chinese medicine, Western medicine, psychology and nursing experts, “one person, one policy” to determine the diagnosis and treatment plan, and provide anti-virus, immune regulation and traditional Chinese medicine treatment. All patients are currently in stable condition. At the same time, the city paid close attention to the needs of citizens for medical treatment during the epidemic, optimized and standardized the admission and treatment plans of various medical institutions at all levels, and ensured “all the treatment that should be treated”; 13 yellow code hospitals were set up to fully ensure the admission of “one point and two districts” personnel. diagnosis and treatment.

In response to the rapid increase in the number of confirmed cases and asymptomatic infections in Yantai in the past two days, Wang Guiqiang, member of the Party Committee of the Yantai Center for Disease Control and Prevention, explained the following reasons: timely response, timely management and control, and timely testing. Since the discovery of the epidemic on April 22, the city has quickly identified risk areas through epidemiological investigations, increased the density of nucleic acid testing in the region, and screened out infected people in a timely manner. Combined with epidemiological history, clinical manifestations, and laboratory tests As a result, a clear diagnosis was made.

In addition, this outbreak was caused by the BA.2 variant strain of Omicron. It is more contagious and has a shorter incubation period. At present, it is still in the common incubation period of new coronavirus infection in the past two days. Most of these newly confirmed cases and asymptomatic infections are detected in centralized isolation points, and a few are in closed and controlled areas. The findings show that the division and management of the “three areas” of the closed area, the control area, and the prevention area in the on-site epidemic disposal is scientific, and it has played a good role in risk identification and control.

“Combining with the characteristics of these cases, the epidemic shows obvious spatial clustering, and it may have been hidden for a period of time.” Wang Guiqiang introduced that in the face of the rapid spread of Omicron mutants, strong concealment, Due to the short incubation period and other characteristics, the treatment of the epidemic needs to race against time, fast flow adjustment, fast detection, fast transportation, and fast isolation, and “fast to make fast” to strive to find and isolate all sources of infection in the shortest time, and block the spread of the epidemic. To achieve zero social infection.
