Vector control and ivermectin treatment history, current strategy and infection levels per village.

a CMFL = community microfilarial load as defined in [19], expressed as microfilariae (mf) per skin snip (ss)b CDTI = community-directed treatment with ivermectinc Flies infected with any O. volvulus larval staged Flies infected with O. volvulus L3 larvae in heads and thoraces (the percentages of infected and infective flies were calculated from all flies, collected by both oviposition and host-seeking methods. Details of the total numbers dissected for each collection technique per village per season are presented in S2 Table)e pre-treatment baseline prevalence unknown, with 2000 the earliest date available; multiple ivermectin treatments from 1993 to 1997. In 1992, a mapping survey of the Onchocerciasis Control Programme in West Africa extension stated that ‘the site of Djodji presents the highest transmission potentials of the Eastern extension’[95].Vector control and ivermectin treatment history, current strategy and infection levels per village.
