Long Beach Confirms First Human Case of West Nile Virus This Summer

The Long Beach Department of Health and Human Services is reminding residents to take simple steps to protect themselves from mosquito bites after confirming the city's first human case of West Nile virus (WNV) this summer.
Although West Nile virus-positive mosquitoes have been detected in Long Beach and throughout California this season, this is the first symptomatic human case reported statewide in 2026. With mosquito activity increasing during the warmer months, the Health Department encourages residents to remain vigilant, particularly from June through October when the risk of mosquito-borne illnesses is highest.
While most people infected do not develop symptoms, some may experience fever, headache, body aches, nausea, vomiting or a rash. In rare cases, the virus can lead to serious neurological illness, including brain inflammation or paralysis. Older adults and people with chronic health conditions are at greater risk for severe illness.
Residents can help protect themselves and their families by using EPA-registered insect repellent, wearing long sleeves and pants when outdoors at dawn and dusk, repairing window and door screens, and eliminating standing water around homes where mosquitoes can breed.
The Health Department's Vector Control Program, in partnership with the Greater Los Angeles County Vector Control District and the Compton Creek Mosquito Abatement District, continues to monitor mosquito activity and treat areas with elevated mosquito populations throughout the city.
Residents are encouraged to report increased mosquito activity, learn more about prevention measures and report dead birds, which can help monitor the spread of West Nile virus, by visiting the City's mosquito information webpage. By taking a few simple precautions, the community can help reduce mosquito populations and protect themselves throughout the summer.
