Durability associated efficacy of long-lasting insecticidal nets after five years of household use

摘要

New research by Eliningaya J Kweka and colleagues from the Tropical Pesticides Research Institute, Tanzania evaluates the effectiveness of insecticidal bed nets that have been used for an extended period, typical of use in the field. Long-lasting insecticidal nets (LLINs) have been strongly advocated for use to prevent malaria in sub-Saharan Africa and have significantly reduced human-vector contact. PermaNet~R 2.0 is among the five LLINs brands which have been given full approval by the WHO Pesticide Evaluation Scheme (WHOPES). The LLINs are expected to protect the malaria endemic communities, but a number of factors within the community can affect their durability and efficacy. This study evaluated the durability, efficacy and retention of PermaNet~R 2.0 after five years of use in a Tanzanian community.
