Fig. 3From: Modelling the pulse population-wide nucleic acid screening in mitigating and stopping COVID-19 outbreaks in ChinaBest model fitting results for the transmission dynamic model in Yangzhou and Xi’an. A, C and E are the daily opportunistic confirmed cases from I, the daily confirmed cases from \(E_q\) and the cumulative confirmed cases in Yangzhou, respectively. Similarly, B, D and F are those in Xi’an. The yellow and green curves are the estimated curves in Yangzhou and Xi’an, respectively, with the shadow areas being the corresponding 95% confidence intervals. The circles are the corresponding observed dataBack to article page
