Louisa Messenger (Environmental and Occupational Health) co-published a paper on "Protective efficacy of holed and aging PBO-pyrethroid synergist-treated nets on malaria infection prevalence in north-western Tanzania" in the journal PLoS Global Public Health. 

This study presents the durability of two types of nets with and without the synergist PBO over three years of field use and examines whether this was associated with malaria infection in an area of pyrethroid resistance. The findings of this study demonstrate that the nets' lifespan in this setting was below two years. Aged PBO LLINs still provided better protection against malaria infection than standard LLINs up to two years. It is important that users are aware of the benefits of using nets, even if they become torn — and targeted behavior change communication campaigns may help to reduce the attrition of torn nets.
