What is the effectiveness of appropriately dosed IDA in clearing microfilariae (Mf) from Mf positive people who (i) reported taking triple drug therapy with ivermectin, diethylcarbamazine, and albendazole (IDA) in August 2018, and (ii) did not report recently taking IDA.

This will be investigated by:

• assessing the baseline (current) Mf presence and density before re/treatment with IDA, against which post-treatment Mf presence and density can be compared
• assessing the peak plasma concentration levels of ivermectin, DEC and albendazole in treated Mf positive individuals to identify whether the recommended dosages of medications are sufficient for achieving effective plasma concentrations
• assessing Mf clearance one week following directly observed IDA re/treatment
