To support Member States and other stakeholders, the WHO Vector Control Product Assessment Team in the Prequalification Unit (PQT/VCP) is developing guidance related to the post-market surveillance (PMS) and monitoring of VCPs.

The document below was developed to respond to the requests from stakeholders, including Member States, procurement agencies, and NGOs, for updated guidance on conducting PMS activities for insecticide treated nets (ITNs).  PMS can cover a wide variety of activities and be employed to address different questions and interests from stakeholders. The specific technical questions which may be addressed as part of PMS activities are dependent on the stakeholder and the intent of the monitoring activities.

This document should not be viewed as a checklist nor mandate for PMS activities. Instead, it should be referred to as guidance information that aids in developing PMS activities in the form necessary to address the needs of the stakeholders.
