Florida health officials said Tuesday they found six new locally transmitted cases of Zika virus, plus one more Wednesday, bringing the state's count to 71 cases. Florida has tracked 634 cases of Zika linked to travelers, and says 86 pregnant women are infected.
One doctor at the University of Miami said she'd spoken to pregnant women who may have become infected with Zika in Florida.

"There are four women who I have spoken to in the last weeks who have not left Florida and who are suspected to have gotten their infections here," Dr. Christine Curry, an obstetrician and gynecologist at the University of Miami Health System, told the meeting.
"Even within the last week I have had to make a phone call to a pregnant patient. She was infected because we are struggling to get a handle on this," Curry said to loud catcalls from the audience.
If the cases are confirmed, they would be the first non-travel related cases of Zika seen in pregnant women in the continental United States. The Florida Department of Health declined to provide any more information on the cases.
"SHE WAS INFECTED BECAUSE WE ARE STRUGGLING TO GET A HANDLE ON THIS."
Zika virus has spread explosively across the Americas and the Caribbean and is also spreading in parts of Asia. There's now no doubt it directly causes severe birth defects when pregnant women are infected by it. It can cause a paralyzing side-effect called Guillain-Barre syndrome and also, possibly, other very rare neurological conditions. And there are hints the virus can sometimes affect the brains of babies after they are born, as well as adults.
