Popis: Tracking the genome diversity and evolution of virus like severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was the hotspot of current researches, which were essential for the developing of prevention strategies and therapeutic vaccines. In the current study, a total of 206073 oral or nasopharyngeal swab specimens were collected in 2022 from entry populations originated from Hong Kong, among which 141 whole genome sequences were obtained through next-generation sequencing and analyzed. Two major Omicron sub-lineages were identified: BA.2.2 (70.21%, 99/141) and BA.5 (24.11% 34/141). An average of 53.22 mutations was emerged in the genome, with S protein and ORF1a harboring the highest number of mutations among structure proteins and non-structure proteins (p
