Table 3 Estimated malaria transmission rates by members of the Anopheles farauti complex in Western Province

From: Spatial-temporal heterogeneity in malaria receptivity is best estimated by vector biting rates in areas nearing elimination

Year No. tested Sporozoite positives (%) All night-biting ratea Annual EIRb
P. falciparum P. vivax P. ovale Plasmodium spp.
2014 1546 0.26 0.13 0.06 0.45 16.89 27.91
2015 591 2.03 0.51 0 2.54 6.44 59.73
Overall 2137 0.75 0.23 0.05 1.03 10.81 40.63
  1. aThe value for the all night biting rate was calculated from the landing catches from 18:00 to 00:00 h and adjusted from biting profile which estimated that 59% of biting occurs before midnight
  2. bEIR [infective bites per person per year (ib/p/y)] = Sporozoite rate × Biting rate (6pm-6am) × 365; where the sporozoite rate for all Plasmodium species is used
  3. Note: The villages included in these calculations were those with ≥ 8 sample periods, being Jack Harbour, Kinamara, Nazareth, New Mala, Saeragi
