BF.15 has been detected in most of the city’s COVID-19 infections since 23rd Aug., while some other infections were related to omicron subvariants BA.5.2, BA.5.2.1 and BA.2.2.
All the subvariants of BA.5 are more contagious and harder to discover. The mutant strains found in the COVID cases were highly homologous with some of the strains reported abroad, thus the possibility that the latest COVID flare-up was caused by imported cases cannot be ruled out, Lin said.
