Soil-Transmitted Helminthiases in Secondary School Students in Selected Sites in Two Provinces in the Philippines: Policy Implications

Abstract

The latest World Health Organization (WHO) strategic plan for eliminating soil-transmitted helminthiases (STHs) as a public health problem in children puts the emphasis on school-age children. On the other hand, the Philippine national helminth control program excludes secondary school students in mass deworming for STH. This study determined the prevalence and intensity of STH in a sample of 633 students (14–15 years old) in selected secondary schools in two Philippine provinces. Stool specimens were processed following the Kato-Katz technique and examined for the presence of helminth ova. Overall cumulative prevalence of STH was 31.3%, while prevalence of moderate–heavy-intensity infections was 7.7%, well beyond the WHO target of ≤1% for reducing morbidity in school-age children. Recommendations were made to update the Philippine helminth control program and to re-examine the WHO strategic plan so that helminth prevention and control strategies may also be emphasized for secondary school students especially in high-prevalence areas.
