Zika can cause fever and joint pain. Symptoms are similar to those of dengue and chikungunya and can include a slight fever, headache and pain in the hands and feet.
The virus is especially dangerous to babies. Scientists in Brazil have linked Zika infections to cases of babies being born with small heads, or microcephaly.
The Centers for Disease Control and Prevention is now warning people traveling to Brazil and Puerto Rico to guard themselves against mosquito bites.
There are no known cases of infection by the Zika virus in the United States, though it has been seen in returning travelers.MORE NEWS: Summer Break Ends Early For Some Dallas ISD Schools
