The Aedes aegypti mosquito, known for carrying dengue, yellow fever, and Zika, has established a population in Western Colorado. Previously thought unable to survive the Mountain West's climate, this invasive species is now thriving there. The development raises concerns about disease spread in regions historically inhospitable to it.
The Aedes aegypti mosquito, a vector for serious diseases including dengue, yellow fever, and Zika, was long considered dependent on hot and wet climates. However, a population of this invasive species is now thriving in Western Colorado, part of the Rocky Mountains, where such conditions were previously deemed insufficient for its survival.
This unexpected spread highlights potential shifts in ecological boundaries, possibly influenced by climate change. The story, originally reported by Inside Climate News, is part of the Climate Desk collaboration, emphasizing its ties to broader environmental and ecological issues.
Experts note that the mosquito's presence in the Mountain West could alter public health strategies in the region. While specific timelines for the discovery are not detailed, the publication date of November 15, 2025, marks the reporting of this thriving population. Keywords associated with the coverage include climate desk, science, environment, ecology, climate change, mosquitos, infectious disease, and diseases, underscoring the interdisciplinary implications.
