TULARE COUNTY, Calif. (KFSN) — Tulare County health officials are investigating four cases of suspected West Nile Virus in residents.

They believe three adults and one child have been affected.

Three are from the Visalia area, and one is from Tulare.

It comes as officials confirmed the Saint Louis Encephalitis Virus, also known as SLEV, has been detected in mosquitoes in Tulare County.

Symptoms of SLEV infection are similar to that of West Nile.

Mosquitoes transmit both illnesses.

Most people don’t even know they’re infected and show no signs of symptoms.

But a small percentage do get symptoms, and they can even be deadly in less than one percent of individuals.

Report mosquito presence (anonymously, if you like) by calling the Delta Vector Control District, or your local vector control agency, toll-free, at 1-877-732-8606 or by reporting online at, or on its Facebook page (, Twitter (@DeltaVCD), or Instagram (@DeltaVCD) accounts.
