bAnnual parasite index = proportion of individuals with circulating malaria parasites
cSH = remaining susceptible human population [for details see “Methods” and Eq. (6)]
dObtained by RT-PCR from single field collected mosquitoes
eHuman biting rate, the per capita number of bites per night, calculated with the data obtained from the HLC based on 6-h collection
