Published on August 08, 2022

Tarrant County Public Health has confirmed the first human case of West Nile virus for the 2022 season.

The individual resides in northwest Tarrant County and presented the mild form of the disease, often referred to as West Nile virus fever. Symptoms include headache, fever, muscle and joint aches, nausea and fatigue. People typically recover on their own, although symptoms may last for several weeks.

It was reported that the individual had outdoor activities during the incubation period.

There have been no West Nile virus-positive mosquito pools in the associated area. Additional details are not being released to protect the identity of the patient.

This year’s first positive mosquito pool in Tarrant County was reported in May. Seven positive mosquito pools have been found in Tarrant County so far this year.

Monitoring for the virus in mosquito pools takes place April through mid-November. Local cities and Tarrant County, for unincorporated areas, may perform mosquito treatment as needed.

Residents should take measures to safeguard against West Nile virus. Dump standing water outdoors, use repellent and, whenever possible, dress in long pants and long sleeves.
