Zika Virus

The Zika Virus is actively spreading in the Caribbean, Central and South America.

The virus spreads quickly when infected individuals are bitten by the Aedes species mosquitos, passing the virus to the next person. Unlike other mosquito-borne illnesses spread by species active during dawn and dusk, Aedes mosquitoes are more active during the day.

W.H.O. recommends those planning trips affected areas delay travel. If you have traveled recently to an impacted area, download this Centers for Disease Control guide.

Who’s at risk?

Zika is especially dangerous for pregnant women as the virus may cause physical and neurological abnormalities in newborn babies.


Symptoms usually begin three to seven days after being bitten by an infected mosquito.

  • Rash
  • Joint pain
  • Red eyes
  • Muscle pain
  • Headache
  • Pain behind the eyes
  • Vomiting

The illness is usually mild, with symptoms lasting several days to a week. Severe disease is uncommon, and no deaths have been reported.

The virus can be found in blood during the first week of infection, so individuals experiencing symptoms can reduce the spread of virus by avoiding further mosquito bites.

Contact your health care provider if you are experiencing these symptoms to test for Zika and other mosquito-borne illnesses.


There is no vaccine to prevent and no medicine to treat Zika infections. The best way to prevent infection to reduce areas where mosquitoes breed around your home and use repellents and wear long sleeves, long pants and/or permethrin-treated clothing when outdoors.

Other information


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.
