Zika virus is a mosquito-borne virus first identified in Uganda in 1947 in a Rhesus macaque monkey followed by evidence of infection and disease in humans in other African countries in the 1950s. From the 1960s to 1980s, sporadic human infections were detected across Africa and Asia. However, since 2007 outbreaks of Zika virus disease have been rec...
Most people infected with Zika virus do not develop symptoms. Among those who do, they typically start 3–14 days after infection, are generally mild including rash, fever, conjunctivitis, muscle and joint pain, malaise and headache, and usually last for 2–7 days. These symptoms are common to other arboviral and non-arboviral diseases; thus, the dia...
Zika virus infection during pregnancy is a cause of microcephaly and other congenital malformations in the infant, including limb contractures, high muscle tone, eye abnormalities and hearing loss. These clinical features are collectively referred to as congenital Zika syndrome. The risk of congenital malformations following infection in pregnancy ...
Zika virus is primarily transmitted by infected mosquitoes of the Aedes (Stegomyia) genus, mainly Aedes aegypti, in tropical and subtropical regions. Aedesmosquitoes usually bite during the day. These mosquitoes also transmit dengue, chikungunya and urban yellow fever. Zika virus is also transmitted from mother to fetus during pregnancy, as well as...
Infection with Zika virus may be suspected based on symptoms of persons living in or visiting areas with Zika virus transmission and/or Aedesmosquito vectors. A diagnosis of Zika virus infection can only be confirmed by laboratory tests of blood or other body fluids, and it must be differentiated from cross-reactive related flaviviruses such as den...
There is no specific treatment available for Zika virus infection or disease. People with symptoms such as rash, fever or joint pain should get plenty of rest, drink fluids, and treat symptoms with antipyretics and/or analgesics. Nonsteroidal anti-inflammatory drugs should be avoided until dengue virus infections are ruled out because of bleeding r...
No vaccine is yet available for the prevention or treatment of Zika virus infection. Development of a Zika vaccine remains an active area of research.

Overview. Zika is a mosquito-borne virus, similar to dengue fever, yellow fever and West Nile virus. The infection is associated with a birth defect called microcephaly, which can affect babies born to people who become infected with Zika while pregnant. What You Need to Know.
Most people who become infected with Zika virus do not become sick; but about 1 in 5 people may develop such symptoms as fever, rash, and conjunctivitis (reddened eyes). People who become infected while pregnant may transmit the virus to the fetus, which can result in very serious birth defects, including microcephaly (unusually small head).
