Table 2. Parameter estimates of the transmission model.
Parameter | Description | Median | 95%CrI |
---|---|---|---|
β1 | Transmissibility of primary infection | 0.0019 | 0.000081—0.0089 |
β2 | Transmissibility of re-infection/reactivation | 0.042 | 0.035—0.049 |
z | Relative susceptibility for re-infection | 0.32 | 0.017—0.84 |
Reactivation rate in 0-20 year old females (yr−1) | 0.013 | 0.0042—0.021 | |
Reactivation rate in 20-50 year old females (yr−1) | 0.021 | 0.013—0.029 | |
Reactivation rate in 50-80 year old females (yr−1) | 0.028 | 0.017—0.040 | |
Reactivation rate in 0-20 year old males (yr−1) | 0.0054 | 0.0035—0.013 | |
Reactivation rate in 20-50 year old males (yr−1) | 0.011 | 0.0035—0.018 | |
Reactivation rate in 50-80 year old males (yr−1) | 0.013 | 0.0043—0.021 | |
μρ | Hyperparameter for the reactivation rate (mean) | 0.015 | 0.0047—0.027 |
σρ | Hyperparameter for the reactivation rate (sd) | 0.010 | 0.0050—0.028 |
Parameters estimates (represented by posterior medians with 95% credible intervals) are shown of the transmission model with reactivation and re-infection in the B compartment (model E). This model gives the best fit to the data, as judged by WBIC and WAIC (Table 1). For all parameters the potential scale reduction factor Q is close to 1 (0.999 < Q < 1.001), and effective sample sizes of the parameters neff range from 3596 (β1) to 4457 (μρ).
