Antigen and antifilarial antibody prevalence for A, persons who received treatment (n = 126) and B, persons who did not receive treatment (n = 34) in 2000 (solid bars) and 2001 (cross-hatched bars). The error bar represents the upper 95% confidence interval. Among persons who received treatment antigen and antifilarial IgG1 prevalences decreased significantly. Among person who did not receive treatment, antifilarial IgG1 prevalence increased significantly.
