The West Valley Mosquito and Vector Control District detected the presence of St. Louis Encephalitis (SLE) virus in mosquitoes collected this week near Comet Avenue and Chino-Corona Road in Chino.

“This is the first time since the formation of the district (in 1983) that SLE has been detected in our area,” said district manager Michelle Brown.

SLE has also been detected in the Central Valley, as well as Riverside and Orange counties, she said.

The mosquitoes carrying SLE are not the black and white “Aedes” mosquitoes that have been aggressively biting residents day and night, but the native “Culex” mosquitoes, Dr. Brown said.

SLE is a mosquito-transmitted virus in the “flavivirus family,” which is the same as the West Nile Virus, Dr. Brown said.

Symptoms are similar to West Nile Virus, which include headache, fever, dizziness and nausea.
