In Brief

A clinical study evaluating Transfluthrin and Placebo for Arbovirus Infections. Completed, enrolled 6,949 participants across 2 sites.

Detailed Summary

The primary objective of the study is to demonstrate and quantify the protective efficacy (PE) of a single SR product, in reducing DENV infection and active Aedes-borne virus (ABV) disease in human cohorts. The study design will be a prospective, cluster randomized controlled trial (cRCT). Although not a specific objective of this project, an overall goal is to allow for official recommendations (or not) from the World Health Organization (WHO) for the use of SRs in public health. A WHO global policy recommendation will establish evaluation systems of SR products to regulate efficacy evaluations, thereby increasing quality, overall use and a consequent reduction in disease.
