Zika virus disease is caused by Zika virus that is spread to people primarily through the bite of infected mosquitoes. Sexual transmission also has been documented.
There is currently no vaccine or treatment for Zika. The most common symptoms of Zika are fever, rash, joint pain, and conjunctivitis (red eyes). In previous outbreaks, the illness has typically been mild with symptoms lasting for several days to a week after being bitten by an infected mosquito. Zika virus infection in pregnant women is a cause of microcephaly and other severe fetal brain defects. Zika also has been linked to Guillain-Barré syndrome, an uncommon sickness of the nervous system in which a person’s immune system damages the nerve cells, causing muscle weakness and sometimes paralysis.
