Today (September 19), the Xiamen Municipal Government of Fujian Province held a press conference on epidemic prevention and control to introduce the latest situation.
Through the flow of traceability, the expert group has studied and analyzed that the origin of the epidemic was imported cases from other cities, which broke out and spread in densely populated places such as factories, and had spread for 2 to 3 generations before the first case was reported, resulting in a severe and complicated epidemic.
Our organization performed genetic sequencing on positive samples, and 28 samples were detected, all of which were delta mutant strains, and were highly homologous, and belonged to the same transmission chain.
