Abstract
After 2 months of relative quiescence, a large coronavirus disease 2019 outbreak occurred in Hong Kong in July 2020 after gradual relaxation of social distancing policy. Unique severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) phylogenetic clusters have been identified among locally acquired cases, with most genomes belonging to cluster HK1, which is phylogenetically related to SARS-CoV-2 reported overseas.
