Acceptability and preferences for Dual-Active Ingredient Long-Lasting Insecticidal Nets in Rural Tanzania: A Mixed-Methods study Open
Background The World Health Organization (WHO) recommends dual-active ingredient long-lasting insecticidal nets (dual-AI LLINs) for protection against malaria in areas with insecticide resistance. The effectiveness of LLINs, however, depen…

Safeguarding malaria control gains in Africa through ‘species sanitation’ and structural resilience Open
To maintain effective malaria control, endemic countries must reinforce their short-term commodity-based approaches with sustainable, longer-term strategies. In Africa, where only a few highly-efficient Anopheles vectors drive most malaria…

Uneasy bedfellows: Public-Private partnerships for malaria control Open
It is argued that reducing poverty is likely to alleviate malaria transmission and that the way to do this is by reducing inequality. The present capitalist system (as opposed to a straightforward market) tends to erode equality and promot…

Time series analysis of survival and oviposition cycle duration of <i>Anopheles funestus</i> (Giles) in Mozambique Open
Background Survival and gonotrophic cycle duration are important determinants of the vectorial capacity of malaria vectors but there are a limited number of approaches to estimate these quantities from field data. Time-series of observatio…

Molecular archaeology: individual human DNA and infection profiles from 100 year old mosquitoes Open
Natural history collections represent a vast biological and genetic resource, which has remained largely untapped. We revisit mosquito collections of varying ages; some made by early tropical medicine pioneers over 100 years ago. By applyi…
