West Nile and St. Louis Encephalitis Viruses remain in the Valley. Alarm raised for disease risk as invasive species also found in Desert Hot Springs.

“Residents and visitors to the Coachella Valley need to stay alert and aware of the dangers of mosquito-borne diseases,” says Tammy Gordon, Public Information Officer for the Coachella Valley Mosquito and Vector Control District. “West Nile and Saint Louis Encephalitis viruses can be dangerous and both are in mosquitoes we have been testing in the Valley.”

Mosquito samples in Coachella and Northshore were both positive for Saint Louis Encephalitis virus (SLEV) for the first time this year. SLEV was also recently detected in a sample from Thermal. In the past two weeks, West Nile virus (WNV) has been detected in mosquito samples from La Quinta, Mecca, and Oasis. So far in 2019, there have been no human cases of SLEV and ten human cases of WNV in Riverside County.
