Las Vegas-area officials confirm first West Nile case of 2026
Southern Nevada Health District confirmed Clark County’s first West Nile case of 2026, said the patient has recovered, and urged mosquito precautions.
Southern Nevada health officials have confirmed Clark County’s first human West Nile virus case of 2026, a reminder that mosquito season is already a practical issue for Las Vegas-area homes, yards, and workplaces. The Southern Nevada Health District said the patient is a woman in her 40s with neuroinvasive West Nile virus, that she was hospitalized, and that she has recovered.
SNHD said the woman had traveled to another state where multiple human West Nile cases have been reported and was also in Clark County during the incubation period. The district also said no mosquito pools in Clark County had tested positive for West Nile virus as of the release.
As of June 1, SNHD said its surveillance program had set 920 traps and submitted 957 mosquito pools, representing more than 20,000 mosquitoes, for testing.
What residents should do now
- Dump, empty, or cover standing water around homes and businesses.
- Use an EPA-registered insect repellent when you are outside.
- Wear long sleeves and long pants, especially in the evening.
The practical takeaway for Las Vegas residents is simple: check patios, yards, pool areas, and job sites now, before summer heat and evening activity give mosquitoes more places to breed and more chances to bite.
