Zika

WHAT WE KNOW
  • Zika 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.
  • There is no vaccine or medicine for Zika.
  • Zika can be passed from a pregnant woman to her fetus. Infection during pregnancy can cause certain birth defects.
  • Zika can be passed through sex from a person who has Zika to his or her partners. Zika can be passed through sex, even if the infected person does not have symptoms at the time. 
  • Local mosquito-borne Zika virus transmission has been reported in the continental United States. Learn more.
  • Microcephaly is a birth defect in which a baby’s head is smaller than expected when compared to babies of the same sex and age. Babies with microcephaly often have smaller brains that might not have developed properly.
  • 44 states reported cases of pregnant women with evidence of Zika in 2016. Most were travel-associated.
  • About 1 in 10 pregnant women with confirmed Zika had a fetus or baby with birth defects.
