First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested whether spraying insecticide on indoor walls (Targeted Indoor Residual Spraying) can prevent diseases spread by Aedes mosquitoes, like dengue, chikungunya, and Zika. Over 4,400 children aged 2 to 15 in Merida, Mexico took part. Researchers tracked how many got sick over three transmission seasons to see if the spraying reduced infections.
