Northern California county confirms first human cases of West Nile Virus in 2024

(FOX40.COM) — A county in Northern California has confirmed the first human cases of West Nile virus detected in 2024.

The Yolo County Health and Human Services Agency said two Woodland residents required hospitalization after testing positive for the disease, which the agency says, “highlights the need for continued vigilance and proactive measures to control the spread of this mosquito-borne illness.”

Dr. Aimee Sisson, Yolo County’s public health officer, said, “Last year, several Yolo County residents died from West Nile virus infection. Mosquito bites aren’t just annoying—they can be deadly. Protect yourself with mosquito repellent and clothing that minimizes bare skin.”

She continued, “Most people who become infected after a mosquito bite do not get sick, and the risk of serious illness to most individuals is low. However, about one percent of individuals can develop a serious neurologic illness.”

To reduce the risk of West Nile virus infection, the Sacramento-Yolo Mosquito and Vector Control District recommends following the 7 Ds to reduce mosquito exposure.

• DRAIN any stagnant water to eliminate mosquito breeding sites.
• DAWN and DUSK, when mosquitoes are most active, are times to limit outdoor activities.
• DRESS in long sleeves and pants when outdoors.
• DEFEND against mosquitoes by using effective insect repellents containing DEET, Picaridin, or Oil of
  Lemon Eucalyptus.
• Ensure DOOR and window screens are intact to prevent mosquitoes from entering homes.
• For assistance, contact the DISTRICT at 1-800-429-1022 to address mosquito concerns.
