As global temperatures rise, disease-carrying mosquitoes are steadily expanding into new regions once thought too cold for them to survive. Scientists have documented the northward spread of species such as Aedes aegypti and Aedes albopictus, which can transmit dengue, Zika, and chikungunya. According to the Centers for Disease Control and Prevention, this shift increases the risk of outbreaks in areas with little prior exposure. While the overall threat varies by region, experts warn that climate change is reshaping where mosquitoes live—and who may now be at risk.
