Confirmed COVID-19 local cases and deaths in Hong Kong over the first 4 epidemic waves (A) and wave 5 (B, C). Blue and red bars in panels A and B indicated daily numbers of COVID-19 cases confirmed by reverse transcription PCR and daily number of reported deaths. Bars in light blue in panel B indicate daily numbers of COVID-19 cases detected by rapid antigen tests. Panel C indicates the exponential growth of the reported COVID-19 cases in wave 5 before the epidemic peaked. Six fatal imported cases were also included in panel A; no deaths were reported among persons with imported cases in wave 5.
