Lymphatic Filariasis and Onchocerciasis reached the World Health Organization’s (WHO) elimination threshold in both Plateau and Nasarawa States in north-central Nigeria in 2017 and 2021, respectively.

However, no evidence-informed plan was created to detect or respond to potential recrudescence of the eliminated diseases while waiting for national elimination to occur. To meet this gap, Plateau and Nasarawa States were selected to pilot the development of the WHO integrated post validation/verification surveillance (PVS) planning toolkit for neglected tropical diseases.

PATH conducted the pilot, working in collaboration with The Carter Center – Nigeria as a local partner.
