They therefore constitute serious public health and socio-economic problems in the areas that they occur. The study was undertaken to assess some physical and chemical factors affecting the distribution of Simulium damnosum complex in Oji river basin, Enugu state, Nigeria. Study Design: Larval prospection was carried out in eleven riverine breeding sites in Oji river basin Original Research Article
