Table 1

Symbols in the mathematical model and their meanings. (The daily probability of a susceptible human becoming infected (pm) is 1 minus the probability of being bitten and not being infected. The number of bites received by a human per day is given by aM/H. The daily probability of a mosquito becoming infected (ph) is equal to 1 minus the probability of biting a number of times and not becoming infected, which depends on the proportion of infected humans and the efficacy of transmission.)
