The prevalence of this organism was found in 18.58% and 18.18% of children with and without associated symptoms. The prevalence is higher than in previous studies from Southeast Asia. Most children are commonly infected after 1 year of age. Giardiasis should be suspected in any child with unexplained chronic diarrhoea, abdominal pain and failure to gain weight. The diagnosis is important because the disease is curable after appropriate treatment.Mahidol UniversityMedicineArticleSCOPUS
