Global risk of selection and spread of Plasmodium falciparum histidine-rich protein 2 and 3 gene deletions - Nature Medicine A modeling approach to assess the global risk of Plasmodium falciparum histidine-rich protein 2 and 3 gene deletions identifies ten priority African countries for surveillance and could inform malaria control policies.

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...

Write to your MP.
Fill their post bags. They represent us.
Show the evidence of the catastrophe Israel is wreaking on Palestine and Gaza. It is abundant.
The situation in Gaza is beyond critical. Their minds must be changed urgently. There is no time to lose. Write. Or write again.

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. Apparently the UN is trying to track scale of impact. Please respond. form.jotform.com/250913880478...

Modelling the effects of diurnal temperature variation on malaria infection dynamics in mosquitoes - Communications Biology Mechanistic modelling of the effects of diurnal temperature variation on Plasmodium falciparum sporogony indicates this variation is important in the laboratory, but further validation is required to ...

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...
