Table 1.
Parameter values used in SIYR model. These parameter values result in an R0 = 2.0 in the absence of sexual transmission. Time unit is months (correspondingly months−1 for rates).

| ϕ | degree of intervention to current incidence | 0.054 |
| βC | transmission rate through direct-contact | 0.01334 |
| α | scaling parameter of gamma distribution/number of sexually infectious pseudo-stages | 5 |
| η | rate parameter of gamma distribution/pseudo-stage transition rate | 0.722 |
| ω | mean recovery rate from sexually infectious phase (η/α) | 0.144 |
| p | proportion of directly infectious individuals who become sexually infectious | 0.0–0.5 |
| βS | transmission rate through sexual contact | 0.0–0.5 |
| ψ | probability of disease-induced mortality | 0.7 |
