Scientists have discovered a microbe carried by some mosquitos that prevents the insects from being infected with malaria parasites - and by extension, from transmitting the deadly disease to humans.
“The data we have so far suggest it is 100% blockage, it’s a very severe blockage of malaria,” the team’s Dr Jeremy Herren told the BBC.

The parasite is responsible for the deaths of around 400,000 people every year, most of them children aged under five, but scientists hope the new findings could “be investigated as a strategy to limit malaria transmission”, says the researcher in a newly published paper in the journal Nature.
Scientists could infect male mosquitoes with Microsporidia MB and then release them into the wild, where the insects would pass it on to females and their offspring. Once at least 40% of a region’s mosquito population is carrying the microbe, malaria infection rates in humans should start to fall, according to experts.
Professor Steven Sinkins, from the Medical Research Council-University of Glasgow Centre for Virus Research, told The Times: “It is a very exciting finding, and we very much hope that we can translate it into a new malaria control tool.”
