The Aedes aegypti mosquito that can carry dengue, yellow fever, and Zika was thought to be too reliant on a hot and wet climate to survive in the Mountain West. But now, a population is thriving in Western Colorado. Mosquitoes are often called the most dangerous species on the planet for their ability to spread life-threatening diseases to humans. Of those, malaria, carried by female Anopheles mosquitoes, has long been one of the most devastating. However, as climate change allows the Aedes aegypti to move northward, survive at higher elevations and stay active for longer into the fall, dengue virus is fast emerging as one of the most dangerous of the world’s diseases transmitted by mosquitoes and ticks.The virus is often mild or asymptomatic, but for some people, it can become severe, so painful that it’s nicknamed “break-bone fever.” Can mosquitoes be completely eliminated ?
