Seroprevalence of toxocariasis in children aged 1-9 years in western Islamic Republic of Iran, 2003.

We determined the seroprevalence of Toxocara canis infection in 544 children under 10 years randomly selected from urban and rural areas of Hamadan. An enzyme-linked immunosorbent assay was used for detection of antibodies to T. canis excretion-secretion antigens. Using a questionnaire, epidemiological factors associated with infection were examined, including age, sex, residence. Antibodies to T. canis were detected in 29 children (5.3%) and 19 children (3.5%) were categorized as borderline positive; thus together this gave a prevalence of toxocariasis of 8.8%. No significant differences were found in terms of sex, age and residence.
