Data fitting and simulation results for Guangdong province: (a) Data fitting for the cumulative confirmed cases using both the direct and indirect transmission routes, from January 23, 2020 (day 1) to February 11, 2020 (day 20). (b) Simulation for the cumulative confirmed cases based on data fitting from part (a), for a period of 80 days from February 12, 2020 (day 1) to May 1, 2020 (day 80). (c) Data fitting for the cumulative confirmed cases using the direct transmission routes only, from January 23, 2020 (day 1) to February 11, 2020 (day 20). (d) Simulation for the cumulative confirmed cases based on data fitting from part (c), for a period of 80 days from February 12, 2020 (day 1) to May 1, 2020 (day 80). The reported cases in Guangdong province increased significantly after March 15 (day 33) due to cases imported from abroad.
