The pattern of human intestinal helminth infections in farming communities in different parts of Ondo State, Nigeria.

Faecal samples collected from people inhabiting project areas of Owena River Basin and Rural Development Authority at Okitipupa, Akure Ifon and Ajowa which are located in different geographical areas of Ondo State, Nigeria, were examined for helminth ova and larvae. The common worms were Ascaris lumbricoides, Trichuris trichiura and hookworms with average occurrences of 43.1% 23.4% and 17.0% respectively. Infections were highest in subjects in the age groups of 6-10 and 11-15 years and lowest in those over 25 years. The frequency of occurrence of Ascaris and Trichuris were high in all towns. Hookworms infection rates were 24.6%, 19.7%, 21.5% and 2.1% at Akure. Ifon, Ajowa and Okitipupa respectively. The low hookworm incidence at Okitipupa which is near the coast has been attributed to the heavy soils of clay and silt coupled with heavy rainfall.
