Recently published documents 

Two generic risk assessments (GRAs) have been published for ITNs: Chlorfenapyr and Pyriproxyfen.  

GRAs are intended to be used by applicants, regulatory authorities, and other stakeholders as examples of the implementation of the Generic risk assessment model for Insecticide-Treated Nets, 2nd edition (WHO, 2018).  They use representative values which exemplify currently prequalified ITN products for specific active ingredients to characterize the hazards, exposure, and risk. 

All of the generic risk assessments for ITNs are located on the ITN Guideline page of the PQT/VCP website. 

Updated documents 

Two implementation guidance documents for ITNs have been updated with minor changes. 

The ITN guideline and all associated implementation guidance documents can be found here. 

The specification templates for proposers have been updated to reflect the most recent reference analytical methods (as per the templates' publication date).  As such, users of the Chemical and Microbial manuals are encouraged to refer to the templates as a reference point to identify if updated analytical methods are available.
