First West Nile Virus death confirmed in Mississippi

JACKSON, Miss. (VDN) — The Mississippi State Department of Health has confirmed the state’s first death from a human case of West Nile Virus (WNV) in 2025. The individual, whose identity has not been disclosed, was a resident of Washington County.

Out of respect for the family’s privacy, the department has not released further details regarding the age or gender of the deceased.

This marks the first WNV-related fatality in the state this year. So far, 10 human cases have been reported statewide. A full breakdown of cases by county is available at msdh.ms.gov/wnvcases.

West Nile Virus is primarily spread through the bite of an infected mosquito. The MSDH is urging residents to take precautions both personally and around their homes to reduce the risk of infection.

To protect yourself:

• Avoid outdoor activity during peak mosquito hours, typically from dusk to dawn.
• Use mosquito repellents containing DEET. Products with up to 30% DEET are considered safe for adults, while concentrations of 10% or less are recommended for children ages 2 to 12. Parents of children under 2 should consult a pediatrician before using repellent.
• Wear long-sleeved shirts, long pants, socks and shoes when possible.

To protect your home:

• Eliminate standing water in containers such as tin cans, flower pots, and discarded tires.
• Keep garbage cans covered and prevent water from pooling in them.
• Turn over wading pools and wheelbarrows when not in use.
• Clean and chlorinate outdoor pools, hot tubs and saunas regularly.
