The Los Angeles County Department of Public Health Monday reported the first human case of Saint Louis encephalitis in the region since 1997, and the first case of the disease in the state this year.

The patient, whose name was withheld, is an elderly resident of San Fernando Valley who became ill in late August, according to the DPH. Environmental monitoring for SLEV in Los Angeles County began in early spring, and, to date, one mosquito sample from Playa Vista has tested positive for the virus, according to the health department.

“Since Saint Louis encephalitis is transmitted to people through the bite of an infected mosquito, the best way to prevent getting infected is to prevent mosquito bites,” said Dr. Muntu Davis, Los Angeles County’s health officer. “Residents should protect themselves by using EPA-registered repellent to keep mosquitoes from biting you, and checking for items that collect standing water in their homes or yards where mosquitoes can breed to tip out the water.”
