This week, a New Hampshire man died of eastern equine encephalitis (EEE), a rare but extremely serious disease caused by a mosquito-borne virus. Human cases of EEE have also been reported in Wisconsin, New Jersey, Massachusetts, and Vermont, causing some municipalities to step up mosquito control efforts or attempt to limit outdoor activities during peak mosquito times at dawn and dusk.
Other mosquito-borne diseases are on the rise as well. Oropouche fever, a viral disease typically found in South America, has been spotted in the US—and in Brazil, health officials are reporting an 800% increase in the disease. Dengue fever, also spread by mosquitoes, has been increasing across Europe. Experts attribute all the surges to climate change, which has brought warmer, wetter weather that has allowed mosquito populations to thrive and expand their ranges.
Sophie Bushwick of New Scientist joins guest host Rachel Feltman to talk about climate, mosquitoes, and disease, and how communities are trying to curb the spread. They also tackle other stories from the week in science, including a puzzling result in a dark matter search, how fruit flies change their threat perception during courtship, and investigations into how marmoset monkeys call each other by name.
