Densities and microfilaria repopulation rates after first (day 90) and second ivermectin treatments (day 455).

Geometric mean densities (mf/skin snip) of O. volvulus microfilaria and repopulation rates observed at day 90 following the first study IVM treatment (day 90) and second IVM treatment (day 455) in the 10 onchocerciasis endemic communities studied in Ghana.*All data are based only on the subjects that were nodulectomized. At days 90 after the first study treatment and day 90 after the second study IVM treatment (i.e., day 455), there were no differences in skin mf repopulation (mf count as a % of pre-treatment) between five communities (Senyase, Beposo, Hiampe, Baaya and Begbomdo – good response or naive communities). However, three communities (New Longoro, Jagbenbendo and Kyingakrom) had significantly higher († p¶ Previously naïve had received two study treatments.
