This research article examines the Ov16 (onchocerciasis) and Wb123 (lymphatic filariasis) seroprevalence in the Bakoye and Falémé foci in Mali after 24 – 25 years of treatment. Specifically, researchers tested for seroprevalence consistency with elimination of transmission (onchocerciasis) and elimination as a public health problem (lymphatic filariasis).
