Comparison of antigenemia by ICT and FTS RDT, antibody responses to Wb123 and Ov 16 by ELISA , and Wb123/Ov16 Biplex RDT on LF sentinel sites
To compare antigenemia results by ICT and FTS RDT, antibody responses to Wb123 and Ov 16 by ELISA , and Wb123/Ov16 Biplex RDT on LF sentinel sites.
To compare TAS-STH vs. a standalone STH survey in 5 schools surveying 250 kids. TAS-STH Community study will have 6-7 year olds while the STH survey focuses on 10-14 year olds.

(1) Is it possible to eliminate schistosomiasis as a public health problem on Unguja in three years and to interrupt transmission in five years? (2) Is it possible to control schistosomiasis throughout Pemba (prevalence <10%) in three years and to eliminate it as a public health problem in five years? (3) What are the costs, successful strategies, barriers, etc. associated with three different interventions (MDA, vector control, and behavior change)?
