Los Angeles County has recorded its first West Nile virus death of the year, a sobering reminder that mosquito season is in full swing. The victim, a resident of the San Fernando Valley, died after developing severe neurological complications from the infection, according to the county Department of Public Health.
Health officials say the death underscores the real threat the virus poses, especially to older adults and those with underlying conditions. While many people infected with West Nile never show symptoms, about 1 in 5 develop fever, body aches, and fatigue. In rare cases, the virus can cause encephalitis or meningitis, which can be fatal.
So far this year, Los Angeles County has confirmed 15 human cases of West Nile virus, not including separate reports from Long Beach and Pasadena. That number already exceeds the five-year average for this time of year, according to the county's vector control district.
A season of heightened risk
The warm months have always been prime time for mosquitoes in Southern California, but this year's surge in positive samples has put health officials on alert. The county's vector control teams are stepping up monitoring and testing in neighborhoods across the region, from the Eastside to the San Fernando Valley.
“We're seeing more infected mosquitoes than usual, and that means the risk to people is higher,” said a spokesperson for the Greater Los Angeles County Vector Control District. “We need everyone to take simple precautions seriously.”
Those precautions include using EPA-approved insect repellents, wearing long sleeves and pants at dawn and dusk, and—most importantly—eliminating standing water around homes. Mosquitoes breed in even small amounts of water, so checking for clogged gutters, bird baths, and old tires can make a big difference.
Local leaders are also getting involved. Councilmember Imelda Padilla, who represents parts of the Valley, has been sharing prevention tips on social media and urging residents to report dead birds, which can be an early sign of West Nile activity.
“This is about protecting our neighbors, our abuelitos, our kids,” Padilla said in a recent post. “A few minutes of yard work can save a life.”
Community groups across the county are organizing cleanup days to clear vacant lots and unclog drains, and local pharmacies report a spike in sales of repellents. The response has been encouraging, but health experts stress that vigilance must continue through the fall.
There is no specific treatment for West Nile virus and no vaccine for humans, so prevention remains the only defense. If you experience sudden high fever, severe headache, or confusion after being bitten by a mosquito, seek medical care immediately.
