Zika virus is spread to people through mosquito bites. The most common
symptoms of Zika virus disease are fever, rash, joint pain, and conjunctivitis
(red eyes). The illness is usually mild with symptoms lasting from several
days to a week. Severe disease requiring hospitalization is uncommon.
In May 2015, the Pan American Health Organization (PAHO) issued an alert
regarding the first confirmed Zika virus infection in Brazil. The outbreak
in Brazil led to reports of Guillain-Barré syndrome and pregnant
women giving birth to babies with birth defects and poor pregnancy outcomes.
In response, CDC has issued
travel notices for people traveling to regions and certain countries where Zika virus
transmission is ongoing.
