The city of Dallas has confirmed its 5th case of West Nile virus this year. Last year, the state of Texas lost 89 lives due to the said virus.

The fifth case of West Nile virus in Dallas City has afflicted a 51-year old man from Duncanville. According to a report by CBS, the victim was hospitalized with a neuroinvasive form of the virus.

The neuroinvasive form of the West Nile virus is the most severe form, affecting the nervous system of the individual. This affects less than 1 percent of people who are infected with the virus, says the Centers for Disease Prevention and Control.

The neurologic illness that comes with the infection includes encephalitis or meningitis, which is an inflammation of the brain and the surrounding tissues. Symptoms for the neuroinvasive form of the West Nile virus include headache, high fever, neck stiffness, disorientation, coma, tremors, seizures and paralysis. Approximately 10 percent of those who develop the neuroinvasive form of the West Nile virus die.

According to an in-depth report by NBC 5, the "Culex" mosquitoes are the ones that can potentially carry the West Nile virus. Southern House mosquitoes are the "Culex" species found most frequently in North Texas, it adds.

Zachary Thomspon, Director of the Dallas County Health and Human Services (DCHHS) told CBS:

"Dallas County wants to alert the public that the mosquitoes that carry West Nile virus are here and they're active. Our mosquito surveillance program and the county and municipal abatement teams are taking the appropriate actions to ensure the safety of our residents. However, it is important that residents do their part by taking the necessary precautions to avoid exposure to the virus."

DCHHS has already confirmed 15 mosquito traps positive for the West Nile Virus July of this year. The 15 mosquito traps which tested positive were located in Cockrell Hill, Grand Prairie, Duncanville, Mesquite and Highland Park.
