Comparison of FTS antigen and Wb123 ELISA in a co-endemic LF and Loiasis area (Or Integrated lymphatic filariasis and Loiasis mapping)
Compare lymphatic filariasis FTS antigen prevalence to the Wb123 antibody prevalence in an area co-endemic with Loa-loa. Refine LF prevalence with FTS and provide evidence for MDA intervention by excluding areas where prevalence of ICT card is due to Loa loa cross reaction; 2) Provide additional data to address the influence of Loa loa cross-reaction and the specificity of antigen rapid test positive result alone to identify ongoing LF transmission in areas co-endemic for LF and Loiasis.
