Objective:
Describing soil-transmitted helminthiasis prevalence and trends in children aged less than 15 in the village of La Virgen, Cundinamarca.
Methods:
Three non-random surveys were carried out on school-children aged 0 to 15 years. Intestinal parasitism was determined In the three cross-sectional studies by direct examination of fecal samples and modified Ritchie-Frick concentration method. Intestinal parasitism distribution was analysed and the trend during 1995-2005 described.
Results:
The prevalence of intestinal parasitism in children aged less than 5 increased from 62,5 % in 1995 to 66,7 % in 2001 and to 69 % in 2005; soil-transmitted helminthiasis prevalence in this age group was 37,5 % in 1995, 23,6 % in 2001 and 27,6 % in 2005. The prevalence of intestinal parasitism for children aged over 5 increased from 86,2 % in 1995 to 89,1 % in 2005; soil-transmitted helminthiasis prevalence was 62,9 % in 1995, 39,8 % in 2001 and 23,9 % in 2005.
Conclusions:
Soil-transmitted helminthiasis was endemic and presented high prevalence during the study period. Effective control measures are needed to prevent intestinal parasitism in pre-school and schoolchildren.
