Abstract:
Four hundred and six soil samples collected from five schoolyards in Mai Trung Commune, Bac Giang Province, Northern Vietnam, from 2005 to 2007 were examined for helminth eggs using a sucrose centrifugal flotation method. The soils around latrines was found to be heavily contaminated with Ascaris sp. eggs. The contamination rate of Ascaris sp. eggs at each school and prevalence of ascariasis among the school children showed a positive correlation (P&It;0.05). This indicated that examination of soil from the area around latrines for Ascaris sp. eggs is a useful method to estimate the prevalence of ascariasis among school children.
