Mosquito-borne diseases spiked across the world this year. In the US, eastern equine encephalitis, a rare but deadly disease with a 30% mortality rate, has killed five people. In Brazil, cases of Oropouche virus, a disease similar to dengue, are up 800% since last year, while globally this is also the worst recorded year for dengue itself: There have been 11 million confirmed cases and 7,000 deaths, almost double last year’s already high numbers. Experts say climate change is driving the increase, as more areas become habitable to mosquito species that spread disease. Aedes albopictus’ range in Europe doubled between 2013 and 2023, and mosquito season in the US has expanded by two weeks since 1979, New Scientist reported. |
