The sequencing results indicated that the genomic characteristics of the Manzhouli cases were different from recent cases detected in Kashgar Prefecture, Tianjin Municipality, . The source of the virus was not likely a spillover event from a host or intermediate host.

Since November 21, the Manzhouli Government carried out large-scale epidemiological investigations and comprehensive nucleic acid testing. All persons that had contact with the cases or entered from the land port at Manzhouli underwent nucleic acid testing. Further investigation is still being conducted.
