Zika is a virus carried by mosquitoes. It has been found all over the world.
Zika virus may be transmitted by sexual contact, a blood transfusion, or a mosquito bite. It is most often transmitted by mosquito bites in areas of the world where Zika is common.
Zika virus infection is associated with pregnancy complications. Pregnant women infected with Zika have an increased risk of having children with microcephaly or of having a miscarriage. Microcephaly is a condition of a small head circumference.
The symptoms of a new Zika infection are a low grade fever, itchy eyes, an itchy rash, and joint pains in the hands and feet.
Zika is suspected when exposure to a Zika source is present (such as a mosquito bite in an area with Zika) and there are two typical Zika symptoms (above). A lab test for antibodies to Zika can help to support the diagnosis. There are other tests that are used to confirm the diagnosis.
There is currently no approved treatment for Zika virus.
