The Surge of Mosquito-Borne Diseases

Amid changing climates, mosquitoes are redrawing the health map of the United States, one bite at a time.

Here at Vox’s climate team, we've been meticulously examining a persistent yet escalating issue: the increasing prevalence of diseases spread by mosquitoes and other vectors across America.

Mosquitoes are often dismissed as a mere annoyance of the warmer months. However, with climate change, urban development, and international travel, their presence—and the diseases they bring—are expanding. West Nile has firmly established itself nationwide. Diseases like dengue, chikungunya, and malaria are beginning to resurface, and the Oropouche virus, previously confined to the Amazon, is appearing in US-bound travelers from South America.

Correspondent Umair Irfan has been examining these phenomena through various lenses. In Texas, extensive mosquito monitoring efforts demonstrate how vulnerable we are to risks breaching our preventive barriers. His observations also underscore the weakening state of US public health infrastructure amid rising threats. To aid public understanding, he's crafted a practical guide detailing the seven most critical mosquito species for disease in the US.

These narratives intertwine into a comprehensive story that goes beyond environmental or scientific inquiry, portraying a significant public health crisis affecting communities nationwide. Whether you're in Boston or Houston, these developments in vector-borne illnesses will undoubtedly impact your environment, health, and daily life.

Below, you can explore our related stories, beginning with our illustrated manual of the top seven mosquito threats in the US. Formerly considered 'tropical diseases,' these ailments have extended their reach far beyond the tropics, reminding us all to remain vigilant.
