Intestinal and urinary helminthes are distributed worldwide, particularly in tropical and sub-tropical areas. More than one billion of the world's population, including atleast 400 million school children are chronically infected with Ascaris lumbricoides, Trichuris trichiura and the hookworms (1) while schistosomiasis affects nearly 200 million people in 75 countries. The prevalence of infections and degree of factors predisposing to infection vary from one region to another (2). Most intestinal nematodes like Ascaris and Trichuris are acquired by ingestion of infective eggs from soil contaminated with human faeces containing eggs. Hookworm and Strongyloides stercoralis infections occur when the infective larvae from the soil penetrate the bare skin, usually of the foot. Man acquires taeniasis by ingestion of raw or inadequately cooked beef or pork containing the infective larvae (cysticerci). The intestinal protozoans are transmitted by ingestion of contaminated water or food containing cysts from faeces of infected persons or by interpersonal contact (3,4). The urinary parasite, Schistosoma haematobium, is an infestation in humans by a parasitic blood worm with fresh water gastropod snails as intermediate host vectors. This study was undertaken to study the presence and prevalence of intestinal and urinary parasites in four communities in south-west Nigeria.
