West Nile Virus

West Nile Virus is a disease that spreads from birds to humans through infected mosquitoes. Cases have been reported throughout North Texas as well as most of the United States.

Who’s at risk?

Most people infected with West Nile experience no symptoms, but a small number of people (about 1 in 150) develop a severe form known as West Nile Encephalitis or West Nile Meningitis, an inflammation around the brain which can cause permanent neurological effects and death.

People over age 50 and those who have received an organ transplant are most likely to develop serious symptoms if infected.

Symptoms

Though most people infected with West Nile Virus do not show symptoms, some have experienced:

  • Fever
  • Headache
  • Body aches
  • Nausea
  • Vomiting
  • Swollen lymph glands
  • Skin rash on the chest, stomach and back.
  • Symptoms can last a few days to several weeks. If you experience any of these symptoms, contact your health care provider.

Severe cases

Individuals who develop the more severe West Nile Encephalitis or West Nile Meningitis also experience:

  • Mental confusion
  • Muscle weakness
  • Tremors (shaking)
  • Convulsions
  • Paralysis
  • Coma

Monitoring

Mosquito traps have been placed at 42 Fort Worth fire stations, and will monitored. Mosquitoes will be tested, in partnership with Tarrant County Public Health, for West Nile virus and St. Louis encephalitis.

Mosquitoes are not tested for the Zika virus since this virus hasn’t been identified locally.
