The new Omicron variant has caused successive infections in Shaoguan, according to the local government.

The latest outbreak in the city has two major transmission chains, respectively caused by Omicron variants BA.5.1.7 and BF.7, both highly infectious with fast spreading capability.

The subvariant BA.5.1.7 caused several infections on the same transmission chain in the city during a dinner gathering on Oct. 1, said the local government.
