Indio, CA, April 18, 2019:
A combination of an unusually wet winter and a spike in temperatures could result in increased mosquito-borne virus activity, such as West Nile and St. Louis encephalitis. The Coachella Valley Mosquito and Vector Control District is currently trapping twice the mosquitoes than is normal this time of year when compared to the 5-year average. These factors point to an early and active mosquito season. To raise awareness and educate Californians about the public health threat mosquitoes pose to our communities, the California Legislature declared April 21-27, 2019 “Mosquito Awareness Week."
