Zika outbreaks are currently happening in many countries and territories. If you will be traveling please visit the CDC Traveler’s Health website for the most recent travel information.
Zika virus spreads to people primarily through the bite of an infected Aedes species mosquito. Zika can also be passed through sex from a person who has Zika to his or her sex partners and it can be spread from a pregnant woman to her fetus. People can protect themselves from mosquito bites and getting Zika through sex.
Most people infected with Zika won’t have symptoms or will only have mild symptoms. The most common symptoms are fever, rash, joint pain, or red eyes. Other common symptoms include muscle pain and headache. 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.
Zika infection during pregnancy can cause fetuses to have a birth defect of the brain called microcephaly. Other problems have been detected among fetuses and infants infected with Zika virus before birth, such as defects of the eye, hearing deficits, and impaired growth. There have also been increased reports of Guillain-Barre syndrome, and uncommon sickness of the nervous system, in areas affected by Zika.
There is no vaccination or medication for Zika.
