Researchers have found a way to reduce how effectively mosquitoes can transmit dengue fever, at least in the lab—and their work could be a step toward stopping the spread of the disease, which infects about 390 million people every year and can, in rare cases, be deadly.

The dengue virus is spread by the Aedes aegypti mosquito when the insect takes a bloodmeal from an infected human host. The virus goes through several phases and eventually infects the mosquito’s salivary glands, which means the next person it bites will be exposed.
A recent study in PLOS Neglected Tropical Diseases looks at genetically modified mosquitoes that were designed to be resistant to the dengue virus—and it seems that these researchers’ methods worked.
