Many infected people in Beijing may have the same transmission chain as migrant workers in Chaoyangshizhuang

Beijing News Express (reporter Zhang Lu) On January 20, the 270th press conference on the prevention and control of the new crown pneumonia epidemic in Beijing was held. According to the notification, on January 20, the Municipal Center for Disease Control and Prevention performed whole genome sequencing of the nucleic acid test positive person 1 reported by the city on January 19, and the results showed that the Delta variant strain (AY.30 evolutionary branch) was completely consistent with the virus sequence of the nucleic acid test positive person notified by the city on January 18, and belonged to the same transmission chain.

The reporter noted that the positive nucleic acid test reported on January 18 is a migrant worker in Chaoyang Shigezhuang Village, which has attracted much public attention. He went to the nucleic acid testing point in Chaoyang District for nucleic acid testing on the 17th, and on the morning of the 18th, he reported that the nucleic acid test results were abnormal, and at 14:00, the laboratory review result of the Municipal Center for Disease Control and Prevention was positive, and the specific mutation site of the Delta variant was detected. According to the "Healthy Beijing" public account released on the 20th, the migrant worker has been turned into a confirmed case.

On January 19, Beijing reported that the positive nucleic acid test 1 lived in the dormitory of No. 8 North Guangyangcheng Street, Changyang Town, Fangshan District, and had a routine nucleic acid test once a week. On January 19, the nucleic acid test result was reported to be abnormal, and the Fangshan District CDC immediately re-collected his sample for nucleic acid testing, and the result was positive. The Municipal Center for Disease Control and Prevention detected the specific mutation site of the Delta strain. The person has been transferred to a designated hospital for isolation treatment.

The positive nucleic acid test 2 reported on the 19th lived with the positive nucleic acid test person 1 on the same day, and the nucleic acid test result was reported as positive on January 19.

3, 4 and 5 people who tested positive for nucleic acid live in Wanliuyuan Community in Fengtai District, and according to the release of "Healthy Beijing" on the 20th, from 0:00 to 24:00 on January 19, two of them turned into confirmed cases.

According to today's notification, from 0:00 to 16:00 on January 20, there were 5 new confirmed cases of local new coronary pneumonia. Among them, 3 confirmed cases were positive for nucleic acid tests reported on the 19th. This means that the positive nucleic acid test patients in Fangshan reported by Beijing on January 19 were confirmed cases, and one of the positive nucleic acid testers in the Wanliuyuan community in Fengtai District was also turned into a confirmed case.

According to the notification, the positive nucleic acid test in Fangshan 1 is completely consistent with the viral sequence of the workers in Shigezhuang and belongs to the same chain of transmission. Today's newly announced confirmed case 1 is a unit dormitory at No. 8 North Guangyangcheng Street, Changyang Town, Changyang Town, Changyang District, a cold storage administrator, and is a close contact of the nucleic acid test positives 1 and 2 notified on January 19, who once shared the same bathroom. This also means that the 3 confirmed cases in Fangshan District may all belong to the same chain of transmission as the confirmed cases in Shi gezhuang.

However, the reporter noted that the main travel trajectory of the Shigezhuang case from January 1 to 18 did not involve Fangshan, and from the trajectory of the 3 confirmed cases in Fangshan, their range of activities was mostly in Fangshan, of which the confirmed case of Fangshan 3 went to Daxing on January 18 and took Metro Line 4. However, there is no direct intersection between the three people and the confirmed cases in Chaoyang Shigezhuang.
