Evidence of much wider distribution of the potential West Nile virus vector, Culex modestus, in the UK - Parasites & Vectors Culex modestus is a primary vector of West Nile virus (WNV) in Europe, feeding on both avian and mammalian hosts. Since its rediscovery in the UK in Kent in 2010, its range has been reported throughou...

This is so sad. Burkinabe scientists have been at the forefront of the development of GM mosquitoes. They have been meticulous and patient, showing how this technology should be implemented. I fear this decision will cost a huge number of lives. www.malariaworld.org/news/after-h...

"we found that mosquitoes are drawn to those who avoid sunscreen, drink beer, and share their bed".......

🚨 New publication!
Our RCT in 🇧🇫 Burkina Faso & 🇨🇮 Côte d’Ivoire shows that adding either non-pyrethroid indoor residual spraying (IRS) or intensive behaviour change communication (BCC) to LLINs reduces #malaria burden.

Questionnaire on the use of the Demographic and Health Surveys (DHS) data Please click the link to complete this form.

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...

March issue of The Lancet Microbe will be online next week, but you can read our editorial already.

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 “The 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-...

Super exiting paper from Olivia Lamera & Meta Roestenberg et al using GM malaria infected mosquitoes to vaccinate people against malaria. Early days and the use-case unclear but really interesting science. www.nejm.org/doi/10.1056/...

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.
