A survey of 5595 primary school children in Lagos State showed that most of the children were over-loaded with parasitic infestations which included malaria (37.7%), schistosomiasis (13.4%), ascariasis (74.2%), tichuriasis (75.8%), hookworm (29.%) and tungiasis (49.5%). Multiple infections were observed with about 16.2% harboring all the causative organisms of the parasitic diseases enumerated above. The high prevalence of parasitic infestations among children is an index of the community''s low level of health and also of inadequate health education.
