Community-directed treatment with ivermectin (CDTI) was developed in the mid 1990's as a solution for the control and elimination of onchocerciasis. It requires that ivermectin be administered continuously over a period of at least 14 years with community involvement before elimination can be achieved.


The objective of this study is to assess the performance of CDTI strategy for control and elimination of onchocerciasis in endemic Local Government areas of Edo State.


A descriptive evaluation in a cross-sectional, descriptive study design was conducted among 720 community members selected from six communities using multistage sampling technique, 11 Community directed distributors (CDDs), and 17 health workers involved in the implementation of the CDTI strategy in Edo State. Primary data were collected using an interviewer's administered questionnaire while secondary data were obtained from the State Ministry of Health. IBM SPSS version 21 software was used for data analysis.


The highest therapeutic coverage (95.5%) was observed in Aden II community while the least therapeutic coverage (56.6%) was observed in Imeke community. Regarding the performance indicators, ivermectin supply, work of CDDs, training, monitoring and supervision, finances by communities had scores ≥2.5 and were therefore considered as having satisfactory performance. However, community participation and ownership and health education and mobilization had scores <2.5 and as such considered as having unsatisfactory performance.


Sustainability of the CDTI program in the study area is likely but not guaranteed as there is need for improvement in areas regarding community mobilization, participation, and ownership.
