Intestinal parasitic infections in schoolchildren in a suburban area of Hanoi, Vietnam.
An epidemiological study on intestinal parasitic infections among schoolchildren in a suburban area of Hanoi, Vietnam, was conducted. Of the 217 schoolchildren involved in this study, 166 (76%) were positive for at least one of nine species of parasite (six helminths and three protozoa). Among the helminth parasites, Trichuris trichiura (67%) was detected the most frequently followed by Ascaris lumbricoides (34%) and hookworm (3%). In the case of protozoan parasites, Entamoeba coli (8%) was the most frequently detected followed by E. histolytica (2%). No Cryptosporidium parvum or Cyclospora sp were found. A questionnaire survey revealed that there was no positive relationship between parasite infection and the children's school records, educational background or parental income, which have been known to play a role.
