Climate change may be lengthening tick and mosquito seasons

Experts warn that climate change is creating ideal conditions for ticks and mosquitoes to reproduce for longer periods, increasing the risk of diseases such as Lyme disease, West Nile virus, and malaria. Record rainfall and high temperatures across much of the U.S. are providing abundant breeding grounds for insects. Health experts from the University of Wisconsin–Madison and Stanford University say these conditions highlight how climate change is already affecting human health. Protection measures include using insect repellent or hiring professionals to spray backyards.
