First human West Nile virus cases confirmed in Texas Denton County and Mississippi Hancock County

Denton County Public Health announced that a resident of the City of Denton tested positive for West Nile virus non‑neuroinvasive disease, marking the first human case reported in the county this season. Assistant Director Juan Rodriguez noted, "We’re seeing more positive mosquito traps in the last few weeks, indicating an increasing risk for contracting WNV, just as we’ve seen in our first human case of the year." The county warned residents to take preventive actions against mosquito bites.

Mississippi's State Department of Health confirmed its first human West Nile virus case of the year in Hancock County. While most infections are asymptomatic, about one‑fifth develop fever and other symptoms. Officials issued guidance on personal protection, such as using DEET repellents, wearing long sleeves, and eliminating standing water to reduce mosquito breeding sites.

Both health agencies emphasized heightened vigilance as mosquito activity rises with the summer heat.
