Figure 2. Estimated incubation periods for the Middle East respiratory syndrome outbreak in Daejeon, South Korea, 2015. Curves indicate estimated cumulative fractions of cases corresponding to the incubation periods, estimated by creating log-normal density functions fitting the observed data. Horizontal lines indicate 95% CIs for the 5th, 50th, and 95th percentiles of the estimated incubation periods. A) Total; estimated median incubation period was 6.1 (95% CI 4.7–7.5) days. B) Hospital A; estimated median incubation period was 8.8 (95% CI 7.2–10.4) days. C) Hospital B; estimated median incubation period was 4.6 (95% CI 2.9–6.2) days.
