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.
Though most people infected with West Nile Virus do not show symptoms, some have experienced:
- Body aches
- 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.
Individuals who develop the more severe West Nile Encephalitis or West Nile Meningitis also experience:
- Mental confusion
- Muscle weakness
- Tremors (shaking)
Find out more about the West Nile Virus through your health care provider, or use the resources available on these government public health sites:
- Tarrant County Public Health
- Department of State Health Services
- Centers for Disease Control and Prevention
The City of Fort Worth has 71 trap locations that are monitored weekly. Mosquitoes that are collected are 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.
