Chi-square analysis showing the relationship between the incidence of falciparum malaria and age
| Age group | Positive (%) | Negative (%) | P-value | |
|---|---|---|---|---|
| 2017 | ≤5 | 41 (58.57) | 29 (41.43) | 0.0665 |
| 10–20 | 108 (55.38) | 87 (44.62) | ||
| ≥20 | 63 (44.37) | 79 (55.63) | ||
| 2018 | ≤5 | 44 (44.44) | 55 (55.56) | <0.0001 |
| 10–20 | 258 (50.69) | 251 (49.31) | ||
| ≥20 | 80 (31.01) | 178 (68.992) | ||
| 2017/2018 | ≤5 | 69 (46.62) | 79 (53.38) | <0.0001 |
| 10–20 | 356 (51.44) | 336 (48.55) | ||
| ≥20 | 145 (35.98) | 258 (64.02) |
Notes: Values less than 0.05 are accepted as statistically significant. P-values are from a chi-square test for proportions evaluating significant association of malaria incidence with age. Incidence in 2018 and overall prevalence revealed this significance.
