    • Abstract:
      Background: West Africa includes the most endemic areas in the world with Nigeria being one of the largest countries of West Africa that has been reported to have a high incidence of onchocerciasis. Aim: The aim of this study was to determine Onchocerca volvulus infection among ivermectin-treated population in Ekpan community, Edo State, Nigeria. Setting and Design: A total of 105 participants including 60 males and 45 females with an age range of 15–81 years were recruited in the study. Random sampling technique was employed in the recruitment of participants. Materials and Methods: Two skin snip specimens were taken from the left and right iliac crests of each participant into a microtube containing physiological saline. The skin snips were processed using standard technique and examined microscopically for microfilariae of O. volvulus. Statistical Analysis: The data collected were analyzed using the Chi-square (X2) test and odd ratio. The statistical package used was GraphPad INSTAT. Results: An overall prevalence of 74.3% of O. volvulus infection was observed among ivermectin-treated subjects in Ekpan. Age, occupation, noncompliance of ivermectin treatment, and source of water significantly affected the prevalence of O. volvulus infection among ivermectin-treated population in Ekpan (P < 0.05). Conclusion: Effective distribution of ivermectin and strict compliance of ivermectin treatment are advocated as these efforts will go a long way at controlling as well as reducing the effects of onchocerciasis in this community.
