- S = no. of sporozoite positive mosquitoes/no. of mosquitoes tested
- B = no. of mosquitoes collected/no. of trap nights/calibration factor of 0.30 for A. gambiae complex and 0.68 for A. funestus; and EIR = S × B × 365
- a Calculated as the percentage of people who slept under a bed net the previous night; bed nets were considered to be treated if insecticide had been applied in the previous 12 months
