7. BF.7 is a sub-lineage of the Omicron variant BA.5, and has the strongest infection ability since it is highly transmissible, has a shorter incubation period, and has a higher capacity to cause reinfection or infect even those vaccinated, news agency PTI reported.The high degree of spread in Chinese cities — including the capital city of Beijing — is also being attributed to a "low level of immunity", possbly due to previous infections.

When the first case of BF.7 infection showed up, health expert Dr Rajeev Jayadevan had said, "Ever since Omicron arrived in November 2021, it has been giving off branches which divide into smaller branches. Of these, BA.2 and BA.5 proved to be stronger than the rest. BA.5.1.7 and BF.7 are names given to downstream descendants of BA.5."
