Onchocerciasis is one of the Neglected Tropical Diseases (NTDs) in Nigeria. The rate of spread of tropical diseases to higher altitudes is on the increase, due to climate change and global warming. This is why this research was conducted to determine knowledge, attitude and perception of those suffering from human onchocerciasis in reported endemic communities of Delta State, Nigeria. The study was carried out in two phases. The first phase involved the collection and examination of samples using standard parasitological protocols. Those who volunteered to participate were included in the study. The second phase examined the knowledge, attitude and perception of the infected and was carried out with the aid of a structured questionnaire. The results showed that out of the 1,201 persons, comprising of 826 (68.8%) males and 375 (31.2%) females examined, 138 were positive for the microfilaria of Onchocerca volvulus. The infected consisted of 101 (12.2%) males and 37 (9.9%) females. Most of the infected persons neither knew the name of the disease nor its vector. Rather, they associated the disease to low income and self-esteem. Comprehensive epidemiological surveys of onchocerciasis in remote areas should be carried out and all the affected population treated by the application of a holistic medical approach. People need to be more informed about the biology and local autecology of the vector and parasite of onchocerciasis. This requires proper health education in the public and schools to minimize the risk of disease transmission in the study area.
