Table 5.
The entomological inoculation rate (EIR) of An. arabiensis in five sub-villages of Kolla Shara village, southwestern Ethiopia, July to December 2016.
| Sub-villages | No. collected | No. assayed for CSP | No. positive (CSP rate %) | PfEIR (95% CI) |
|---|---|---|---|---|
| Abullo | 339 | 299 | 5 (1.7) | 17.0 (15.6–19.7) |
| Erze | 260 | 220 | 3 (1.4) | 10.6 (9.4–13.7) |
| Enmba | 143 | 106 | 0 (0.0) | 0.0 |
| Kurishata | 1 | 1 | 0 (0.0) | 0.0 |
| Muja | 23 | 19 | 0 (0.0) | 0.0 |
| PfEIR of village | 766 | 645 | 8 (1.2) | 5.7 (5.2–6.5) |
Pf EIR = (No. days in six month/total no. of catches) × (No. Pf positive An. arabiensis from CDC light trap + (No. Pf positive mosquito/No. ELISA tested) × (No. An. arabiensis collected from CDC light trap - No. ELISA tested). CI = Confidence interval; CSP = Circum-sporozoite protein; SR = Sporozoite rate; PfEIR = P. falciparum entomological inoculation rate.
