Actual (reported)This is a randomised controlled trial that will be conducted in eastern Thailand in a group of schools with approximately 2,000 students aged 7-15 years. Pre-fabricated school uniforms will be commercially treated to ensure consistent high quality of insecticide impregnation with permethrin. A double-blind randomised cross-over trial at the school level will cover two dengue transmission seasons.

Actual (reported)insecticide:placebo incidence rate-ratio (per 1,000 person-years) of laboratory-confirmed dengue cases in school-aged children
Schools are cross-over randomised to insecticide-treated or untreated (placebo) school uniforms, and so the primary outcome is the rate-ratio of dengue fever cases in school children, compared between these two groups.
up to 2 years
comparison between intervention and placebo groups of number of serious skin reactions to insecticide-treated uniforms
up to 2 years
washing only
washing and insecticide treatment
commercial permethrin insecticide impregnation of clothing before transmission season
normal washing of school uniforms, without permethrin insecticide impregnation
