Epidemic curve and sequential Bayesian estimation of the distribution of R for the A/H7N9 influenza outbreak in Zhejiang province, China. A) Daily number of laboratory-confirmed A/H7N9 influenza cases by date of symptoms onset.
Vertical dashed lines indicate the timing of the preemptive live bird market closures
in Zhejiang (15 April). B) Evolution of R estimates as data accumulate over time, assuming a prolonged serial
interval of six days (latent period, k^{-1} = 3 days and infectious period, γ-^{1} = 3 days). Median R (solid red line) and 95% credible intervals (dashed red lines)
are shown. Horizontal dotted line indicates the threshold at R = 1, above which large
epidemics are expected to occur. R, reproduction number.
