Diseases and Conditions

Zika virus


As many as 4 out of 5 people infected with the Zika virus have no signs or symptoms. When symptoms do occur, they usually begin two to 14 days after a person is bitten by an infected mosquito. Symptoms usually last about a week, and most people recover fully.

Signs and symptoms of the Zika virus most commonly include:

  • Mild fever
  • Rash
  • Joint pain, particularly in the hands or feet
  • Red eyes (conjunctivitis)

Other signs and symptoms may include:

  • Muscle pain
  • Headache
  • Eye pain
  • Fatigue or a general feeling of discomfort
  • Abdominal pain

When to see a doctor

See your doctor if you think you or a family member may have the Zika virus, especially if you have recently traveled to an area where there's an ongoing outbreak. The U.S. Centers for Disease Control and Prevention (CDC) has blood tests to look for the Zika virus and other viruses spread by mosquitoes.

If you're pregnant and have recently traveled to an area where the Zika virus is common, ask your doctor whether you should be tested, even if you don't have symptoms.
