It's official. The Zika virus has established a toehold in Florida.
Fourteen people likely caught Zika in a neighborhood north of downtown Miami, health officials said Monday. That means mosquitoes in that area have picked up the virus and are spreading it.
Zika can cause severe birth defects if a woman is infected at anytime during pregnancy.
So the Centers for Disease Control and Prevention is doing something it has never done before: issuing a travel advisory to a part of the continental U.S. because of an outbreak of an infectious disease.
