Comparison of control and transmission of COVID-19 across epidemic waves in Hong Kong: an observational study.

ABSTRACT:

Background

Hong Kong contained COVID-19 for two years but experienced a large epidemic of Omicron BA.2 in early 2022 and endemic transmission of Omicron subvariants thereafter.
