Simplifying mosquito sampling to estimate community biting exposure and malaria indoor vector control impact Insecticide-treated nets (ITNs) are most effective against malaria if mosquitoes attempt to bite people when they are in bed. Collecting the biting behaviour data required to quantify a key metric - t...

USAID cuts have halted Demographic and Health Surveys that are essential for tracking diseases like HIV and malaria. Huge loss that threatens global security and the efficient distribution of aid.

As we try to understand how climate change impacts malaria @isaacstopard.bsky.social looked how daily temperature fluctuations impact development in mosquitoes. Quite a bit it seems, but still unclear in wild mosies. Lovely data from Antoine Sanou but we need more! www.nature.com/articles/s42...

Trump Administration Ends Global Health Research Program The Demographic and Health Surveys were the only sources of reliable information in many countries on metrics such as mortality, nutrition and education.

A very sad and counterproductive decision. Aid when you don’t know where diseases are is immensely inefficient. DHS is a vital long-term resource, both in counties with diseases like malaria, but also those finding new global threats. Everyone will be flying blind. www.nytimes.com/2025/02/26/h...

Target mosquitoes as they sugar feed shows considerable promise. We looked how these new tools could be used alongside existing malaria control and explored reasons why they might not be as good as early mosquito data suggested. Take_home - we just don't know what the mosi is doing!

Crucial WHO Health Emergency Response Faces Budget Cut Of 25% - Health Policy Watch β€œThe immediate response here in WHO was to use our Emergency Response Framework, to realign the functions at the country office to deploy an incident manager

The real damage to emergency response is probably much larger. On top of the cut to WHO, the US deployed much of their funds for emergency response via the CDC and other US organizations. healthpolicy-watch.news/crucial-who-...

Our paper estimates the use of these chlorfenapyr nets reduced overall malaria cases by 65-75%, substantially more than was observed in trials. These nets are likely to be the most cost-effective way of controlling malaria. www.thelancet.com/journals/lan...

Insecticidal nets prevent more malaria than anything else. Trials in Benin and Tanzania show newer nets that kill more mosquitoes are better than those currently used, but they are unable to assess their overall impact as you cannot leave people without a net and unprotected.
