The contribution of different age groups to the human infectious reservoir in the population
| Proportion in the current study (n) | Proportion of population in a census (%) = (P) | Proportion of individuals infecting ≥ 1 mosquito, % (n/N) | Proportion of infected mosquitoes, % (n/N) = (T) | Relative contribution to the infectious reservoir of individuals ≥ 5 years* | |
|---|---|---|---|---|---|
| < 5 years | ND | 19.3 | ND | ND | ND |
| 5–9 | 23.0 (43) | 17.0 | 11.6 (5/43) | 1.6 (14/860) | 19.7% |
| 10–14 | 23.5 (44) | 12.3 | 13.6 (6/44) | 2.3 (20/880) | 19.9% |
| 15–24 | 16.6 (31) | 17.3 | 6.5 (2/31) | 3.5 (22/620) | 43.7% |
| 25–44 | 19.8 (37) | 20.3 | 2.7 (1/36) | 0.4 (3/740) | 5.9% |
| ≥ 45 | 17.1 (32) | 13.8 | 12.5 (4/32) | 1.1 (7/640) | 10.8% |
| Total | (187) | 100.0 | 9.6 (18/187) | 1.8 (66/3740) | 100% |
ND = non-determined; contribution to the infectious reservoir estimated by the formula.
