Two sectional surveys evaluating ITNs use were performed in April (peak of the season of exposure to An. gambiae—survey 1) and June to July (beginning of dry season—survey 2), just after the installation of ITNs (N = 130) in February 2006. The “loss rate” and “correct-use rate” are indicated for each survey, and the P value indicates the significant percentage differences between surveys 1 and 2 (χ2 test).
