Onchocerciasis (river blindness) is a devastating, debilitating Stigmatising and incapacitating parasitic disease that is endemic in tropical and subtropical regions of the world, including Nigeria. Mass distribution of ivermectin (Mectizan) to the endemic parts of the world was initiated by the Onchocerciasis Control Programmes (OCPs). Absolute compliance to the regimen for up to 15 years has been reported to be effective in the control of the disease. The study was carried out in Ohaozara LGA, Onicha LGA and Ivo LGA. The three (3) LGAs made up the defunct Old Ohaozara LGA. A structured questionnaire was used to generate information on knowledge of Onchocerciasis and on the use of ivermectin by the inhabitants of the communities of the study areas. The distribution coverage of ivermectin in the study areas dating from 2010 to 2014 was ascertained with drug distribution charts obtained from Ebonyi State Health Management Board (ESHMB), Abakaliki (the point source of distribution in the state), and from the health centres in communities of old Ohaozara LGA (the service delivery points (SDPs) to inhabitants of the communities. Data was analysed using descriptive statistics. Utilization of the regimen was ascertained by determining the actual number of tablets of mectizan that was administered to the patients at the various health cenrtes (service delivery points (SDPs) in the communities. The percentage utilization of the regimen was determined by dividing the number of mectizan tablets administered to the patients at SDPs with the number of mectizan tablets supplied from state point source of distribution and multiplying by 100. A total of 347, 299 out of 1, 919135 tablets of mectizan supplied to the study areas from 2010 to 2014 were actually utilized, forming an overall percentage utilization of 18.10%. There was adequate supply but very poor utilization of the regimen. The poor utilization resulted from factors including locating of health centres very far from homes of some of the rural villagers, non-yearly compliance with regimen administration, poor health sensitization and education and lack of incentives orpoor incentives to the village-based health workers (VBHWs). Intensification of efforts to cover the lapses in the utilization of the regimen is advocated for a more effective control of the disease. |
