Figure. Number of PCR-positive COVID-19 cases and time-varying reproductive number in study of epidemiology of SARS-CoV-2 Omicron BA.5 infections, Macau, June–July 2022. A) PCR-confirmed COVID-19 cases and deaths in Macau during June and July 2022. Light blue bars indicate daily numbers of COVID-19 cases confirmed by PCR in the community; dark blue bars indicate persons under quarantine; black bars indicate number of reported deaths. Gray bars under the x-axis indicate the number of real-time red-code zones (areas with movement restrictions in place) in Macau. Shaded areas indicate when public health and social measures (indicated by numbers 1–5) were implemented to control COVID-19 transmission. B) Estimates of time-varying Rt to quantify real-time transmissibility of SARS-CoV-2 Omicron BA.5 in Macau. Dotted line indicates Rt of 1. RAT, rapid antigen test; Rt, effective reproductive number
