Parametric estimates of the incubation period distribution for fatal (dotted line) and non-fatal cases (solid line) of laboratory-confirmed influenza A(H7N9) virus infection.
The parameters of the weibull distribution were estimated with the MCMC approach in the fatal and non-fatal cases, respectively. The estimates are for fatal cases: k = 2.30 (95% CrI: 1.80, 2.89) and θ = 4.21 (95% CrI: 3.62, 4.85) and for non-fatal cases: k = 2.03 (95% CrI: 1.62, 2.52) and θ = 3.74 (95% CrI: 3.20, 4.36).
