Year | No. tested | Sporozoite positives (%) | All night-biting ratea | Annual EIRb | |||
---|---|---|---|---|---|---|---|

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 |
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
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
Note: The villages included in these calculations were those with ≥ 8 sample periods, being Jack Harbour, Kinamara, Nazareth, New Mala, Saeragi
