mosquitoes

Scientists are developing new methods to control mosquitoes, the animal that kills more people than any other on Earth. As the climate warms, mosquito seasons are growing longer, giving the insects more time to spread dangerous diseases such as malaria and dengue. Reports highlight how shifting temperatures are expanding the disease threat into new regions and prompting fresh research into targeting the insects.

PBS NewsHour reports on scientists developing new ways to control mosquito populations as rising global temperatures expand the habitats where the insects and the diseases they carry can spread. The segment examines research approaches to targeting mosquitoes as warming climate conditions push the public health threat into previously unaffected regions.

Several Florida counties have declared a state of emergency in response to what health officials describe as a wildly unusual dengue fever outbreak. The mosquito-borne illness, typically rare in the continental United States, has prompted local emergency measures as authorities work to control mosquito populations and curb further transmission. Coverage from national outlets is drawing attention to the outbreak's unusual scale and its implications for public health in the region.

Researchers in Colombia have identified previously unknown viruses and antibiotic resistance genes in mosquitoes and sand flies, revealing that these disease-carrying insects host far more microbial life than expected. The findings suggest the insects could play a role in spreading antimicrobial resistance, adding a new dimension to concerns about mosquito-borne disease in the region.
