West Nile virus kills Orange County man as cases rise nationwide

Health

A 61-year-old Orange County resident, Daniel Clavel, died in a hospital after contracting West Nile virus, prompting local health officials to warn residents about rising mosquito activity. New York City health officials said 30 residents have been diagnosed with West Nile virus this year, surpassing the 18 cases reported in 2025.

Los Angeles County health officials reported 100 confirmed infections and five deaths, leading to intensified mosquito-control measures. County officials linked the surge to record humidity associated with El Niño, which has extended mosquito lifespans and driven the highest case count in over a decade.
