Study: Significant rise in mosquito “disease danger days” in U.S., report warns

This article discusses a new study that shows an increase in mosquito population because of global warming.

As global temperatures continue to rise, the number of mosquito “disease danger days” is increasing across much of the United States, representing a greater risk for transmission of mosquito-borne diseases, according to a new report.

Among the many consequences of climate change is a shift in the pattern, incidence and location of insect-borne diseases, including those spread by the bites of mosquitoes, ticks and fleas. These diseases pose a significant public health risk and can have deadly consequences, warns the report published by Climate Central, a nonprofit news organization that analyzes and reports on climate science.

While a variety of mosquitoes are found throughout the U.S., the researchers focused on two species: Culex and Aedes (encompassing both Aedes aegypti and Aedes albopictus). These mosquitoes both transmit West Nile virus while Aedes mosquitoes also transmit other dangerous viruses, including dengue, Zika, chikungunya, and Yellow Fever.
