Florida's top health officials confirm three women, who recently traveled to Latin America and who are now pregnant, are infected with Zika virus.
Not much is publicly known about these three cases or will be publicly known, due to confidentiality rules.
The state now has 32 cases of Zika, about a third of them in Miami.
All are believed to have been acquired abroad.
Florida officials insist that due to proximity and travel patterns with South American and Caribbean nations, Florida is at higher risk.
