title: Geohelminth infection of children from rural plantations and urban slums in Malaysia.
abstract: This study compares levels of geohelminth infection in children living in rural estates and urban slum areas of Malaysia. The statistical characteristics of geohelminth infection in 1499 children from birth up to 15 years of age, living in rural estates, were analysed according to age, sex and ethnic origin and compared with the same statistics for 1574 slum-dwelling children of similar age groups and ethnic origins. The prevalence and intensity of ascariasis and trichuriasis were significantly higher among children from the urban slums. Slum-dwelling ethnic Indians and Malays had higher levels of infection with Ascaris lumbricoides and Trichuris trichiura than their rural counterparts, but the infection status of the ethnic Chinese in the 2 areas was similar. Hookworm infection was similar in both areas, indicating that hookworm infection is neither necessarily nor solely a rural disease. These results suggest that urban slum children are at greater risk of ascariasis and trichuriasis than their rural counterparts.
