Zika virus

The Zika virus is spread mostly by the bite of an infected Aedes species mosquito (Ae. aegypti and Ae. albopictus). These mosquitoes bite during the day and night.  Zika can be passed from a pregnant woman to her fetus. Infection during pregnancy can cause certain birth defects.  There is no vaccine or medicine for Zika.  Local mosquito-borne Zika virus transmission has been reported in the continental United States.

Many people infected with Zika virus won’t have symptoms or will only have mild symptoms. The most common symptoms of Zika are

  • Fever
  • Rash
  • Headache
  • Joint pain
  • Red eyes
  • Muscle pain

Symptoms can last for several days to a week. People usually don’t get sick enough to go to the hospital, and they very rarely die of Zika. Once a person has been infected with Zika, they are likely to be protected from future infections.  (Credit: CDC)
