A survey of users on the WHO insecticide susceptibility tube test kit

The WHO susceptibility test kit has been extensively used for monitoring of insecticide resistance in disease vectors for many years. Over the years, users have reported issues with these kits and potential improvements to WHO in an ad-hoc manner. To systematically determine whether the reported issues were widespread and to collate potential improvements to the kit, a survey of users was put online from 30 June to 15 October 2023. The results from this survey are reported in this report.
