Assessment of perceived adverse events and acceptability
ADVERSE EVENTS
To identify and document any perceived adverse events associated with the IRS application of each insecticide, a questionnaire was administered to each spray operator after each day of spraying, at the end of the IRS campaign and one-month post-spraying. A questionnaire was also administered to the heads of households of randomly selected households in each study arm immediately after spraying and was repeated at 6 months post-spraying. Study participants were encouraged to contact members of the study team if they experienced health issues that they believed were related to the IRS applications.
