After genetic sequencing analysis and comparison, the epidemic situation in Xuchang Yuzhou City and the epidemic in Zhengzhou City are homologous, and the virus gene sequencing is a Delta strain.

Subsequently, according to the office of the Anyang City New Crown Pneumonia Epidemic Prevention and Control Headquarters, Anyang City found 2 cases of local new coronavirus nucleic acid positive in the active test population. After the whole genome of the virus was sequenced by the laboratory of the Henan Provincial Center for Disease Control and Prevention, it was shown that all of them were BA.1 branches of the Aomi Kerong variant, which belonged to the same transmission chain as the existing local epidemic situation in Jinnan District, Tianjin. Combined with the results of epidemiological investigation and gene sequencing, the source of infection of this epidemic in Anyang City was basically identified as a college student who returned to Tangyin County of Anyang City from Jinnan District of Tianjin City on December 28, 2021.
