  1. Prevalence of Plasmodium species was compared between the Goma Tsé-Tsé and Madibou districts
  2. The Chi2 test was used to compare the proportion of cases between the two districts.
  3. N Overall number of participants, n1, n2 total number of participants in Goma Tsé-Tsé and Madibou districts, respectively
  4. **Significant difference in prevalence between the two districts according to overall microscopic findings at P < 0.0001 and according to sub-microscopic study at P = 0.0099
