Tarrant County health officials have confirmed the season's fist human case of West Nile virus Monday.
The affected person has West Nile fever, rather than the more serious neuroinvasive disease, officials said. Further information about the case has not been released in order to protect the person's identity.
Tarrant County had 44 human cases of West Nile virus in 2016, including one death.
Officials said West Nile fever can involve headache, fever, muscle and joint aches, nausea and fatigue. The illness may last for several weeks, but people typically recover.
Symptoms of West Nile neuroinvasive disease include neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness and paralysis. The neuroinvasive form of the disease can be deadly.
