Initial proportion of infected humans 0 Supposed
Infectious meal rate from humans to mosquitoes 0.3 [41, 42]
Mortality rate of uninfected mosquito [k] (−90.66+9.54 T−0.18 T2)−1 [43]
Mortality rate of infected mosquito 1.56 k [44]
Infectious bites rate from mosquitoes to humans 0.2 [42, 43, 45]

Explicit Calculations
Dynamic of human-infected population [I(t)] I(t)=NHI(t1)+I(t1)NRH(t1)+NSTE(t1)H
Dynamic of human-infected population [R(t)] R(t)=R(t1)+NRH(t1)HLI(t1)H
Dynamic of susceptible-human population [S(t)] S(t) = 1−[I(t−1)+R(t−1)]
Dynamic mosquito-infected population [J(t)] J(t)=NMI(t1)+J(t1)DIM(t1)+NSCE(t1)M
Temperature 25+5Sin(t4*30π)2

T = Temperature, t = Time, NSTE = New serotype transmission event, NHI = New human infection, NRH = New recovered human, HLI = Human immunity loss, NMI = New mosquito infection, NSCE = New sequence consolidation events, DIM = Death of infected mosquito.
