A prevalence study for intestinal parasites among 305 infants and young children was conducted at the Paediatric wards of the General Hospital Kuala Lum.pur, Malaysia. 40.8 percent of children were infected with at least one type of intestinal parasites: 39 percent were found to be infected with intestinal helminths and 4.26 percent with intestinal protozoa. Ascaris formed 17.38 percent of the infestation followed by Trichuris (14.75 percent) and hookworm (2.95 percent); 0.3 percent of the cases had Strongyloides stercoralis; 2.30 percent and 2.62 percent of the children had Entamoeba histolytica and Giardia lamblia respectively. Indian children were the predominant group found infected, followed by the Chinese and Ma lays. A significant drop in infestation rate of soil-transmitted helminths was detected among the Malays. The significance of the changing pattern in the epidemiology of soil-transmitted helminths is
discussed. A brief review of literature is also presented.
