A Brazos County resident is the first confirmed West Nile case in Texas for 2025, prompting officials to warn residents to take mosquito precautions seriously.

West Nile Virus was first reported in the U.S. in 1999. The virus spreads through mosquito bites, although most people who catch it won’t experience symptoms. About 20% of those infected will develop symptoms such as fever. Less than 1% of those infected will develop a more severe and sometimes fatal illness.
