To assess community-directed treatment coverage with Ivermectin (CDTI) in Onchocerciasis-endemic communities in Birnin Kudu local government area (LGA) Jigawa state.
This was a community-based multistaged cross-sectional survey based on probability proportional to size. The study involved the administration of a questionnaire on 2021 respondents from 207 households. Also, 30 Community Leaders and Community Directed Distributors (CDDs) were purposively selected for interview from the communities visited.
Overall, 2021 respondents from the 2031 sampled population took part in the study giving a response rate of 99.6%. Slightly above half, 1130 (55.9%) were males. The geographic and therapeutic coverage of mass drug administration of Ivermectin achieved in the LGA was 100% and 79.9%, respectively. The key factors affecting coverage includes the unavailability of drugs (48.8%), absenteeism of some of the household members (31%), and inadequate incentives to the CDDs by the government and poor record keeping by the CDDs.
This study found that the minimum geographic and therapeutic coverage of Ivermectin distribution was achieved by CDD as recommended by the World Health Organization for the control of onchocerciasis. For this to be sustained and to achieve elimination, there must be an adequate supply of ivermectin, training of CDDs, retraining of CDDs, adequate supervision in record keeping, and health education to the community.
评估在吉加瓦州比尔宁·库杜地方政府区(LGA)的盘尾丝虫病流行社区中,伊维菌素(CDTI)的社区定向治疗覆盖率。
这是一项基于概率比例的社区为基础的多阶段横断面调查。该研究涉及对来自 207 户家庭的 2021 名受访者进行问卷调查。此外,还从所访问的社区中选择了 30 名社区领导人和社区定向分销商(CDD)进行访谈。
总体而言,来自抽样人口 2031 人的 2021 名受访者参加了这项研究,应答率为 99.6%。略高于一半,即 1130 名(55.9%)为男性。在 LGA 进行的伊维菌素大规模药物治疗的地理和治疗覆盖率分别为 100%和 79.9%。影响覆盖率的关键因素包括药物不可用(48.8%)、一些家庭成员缺勤(31%)、政府对 CDD 的激励不足和 CDD 记录保存不善。
这项研究发现,CDD 实现了伊维菌素分配的最低地理和治疗覆盖率,这是世界卫生组织推荐的控制盘尾丝虫病的覆盖率。为了保持这种覆盖率并实现消除,必须有足够的伊维菌素供应、对 CDD 的培训、对 CDD 的再培训、对记录保存进行充分监督以及对社区进行健康教育。
