Evaluation of the efficacy of insecticide-treated scarves to protect children from the trachoma vector (Diptera: Muscidae): A phase II randomised controlled trial in Oromia, Ethiopia.

Background: The eye-seeking fly can act as a vector for ocular , causing trachoma, yet there has been very little research on control measures. We investigated whether insect repellent products, specifically insecticide-treated clothing, could provide personal protection to the user from eye-seeking flies.

Methods: We first conducted a series of phase I laboratory studies to inform our choice of field intervention.
