First West Nile virus death of 2026 in California reported in Kings County
KINGS COUNTY, Calif. (KFSN) -- A Lemoore resident has died after contracting West Nile virus, marking California's first West Nile virus-related death this year, according to Kings County officials.
The case was reported July 20, Kings County said.
Health officials say West Nile virus is a seasonal concern and is spread by mosquitoes that breed in standing water.
"It is something that every year during this time, we have positive mosquito pools, so the mosquitos lay eggs on standing water, like ponds and lakes, so that's where it puts it at risk for people that are out during dusk and dawn," said Nichole Fisher, a supervising nurse with Kings County Public Health.
Fisher said most people infected with West Nile virus experience mild flu-like symptoms or no symptoms at all.
She said that of the three cases reported in Kings County this year, the Lemoore case was the first symptomatic one.
"If it's something that is going to impact you in a larger way you can see neurological conditions like difficulty walking, difficulty doing your normal activities," Fisher said.
County officials said they cannot release details about the individual who died, but cautioned that older adults and people with pre-existing health conditions should be especially careful.
Matthew Boyett of Kings County said officials are encouraging residents to remember the "three D's" for mosquito protection:
- DEET: Use repellents containing DEET
- Dusk/Dawn: Take precautions during dawn and dusk when mosquitoes are most active
- Drain: Drain standing water around homes and properties
Kings County officials say West Nile virus season could continue through October and are encouraging residents to take preventive measures.
They also advise anyone experiencing symptoms who believes they may have contracted the virus to contact a health care provider.
