Model parameter definitions, values and sources
| Definition | Value [cited literature] | |
|---|---|---|
| b H | Transmission coefficient (vectors → hosts) = bite rate (day−1) × transmission probability | 0.1 = 1/3 × 0.3 [47] |
| b V | Transmission coefficient (hosts → vectors) = bite rate (day−1) × transmission probability | 0.007 = 1/3 × 0.02 [48] |
| m | Ratio of vectors to humans | Varied in simulations; values in figure legends |

| κ | Clearance rate of asymptomatic infection (day−1) | 1/200 [49] |
| θ | Level of reduced susceptibility to secondary infection | 0.5 (assumed) |
| τ | Full susceptibility reversion rate (day−1) | 1/1000 [50] |
| μ H | Birth and death rate of humans (day−1) (i.e., stable population) | 1/21,900 (assumed) |
| μ V | Birth (or maturation) and death rate of vectors (day−1) (i.e., stable population) | 1/10 [51] |
| σ | Adjustment factor for asymptomatic transmissibility to vector | 0.25 [52] |
