The CDC has said there needs to be evidence that no new cases have developed for at least 45 days, or about three mosquito incubation periods, before its guidance can change. The domestic travel advisory for Wynwood was issued Aug. 1 and was the first warning against travel within the United States.
Although Scott urged residents to support the art galleries and patronize restaurants in the trendy Wynwood neighborhood during a celebration day at the end of month, federal health officials were much more cautious. They said pregnant women and their partners who are worried about potential exposure to the virus may also consider postponing nonessential travel to all parts of Miami-Dade County. Mosquito season in South Florida continues through the fall, and additional cases could be identified, the CDC said.
Women and men who lived in or traveled to the area "should be aware this location was considered an area of active Zika transmission from June 15 to Sept. 18," the CDC said. Pregnant women should talk to their healthcare providers about getting tested.
Women and men who don't have signs or symptoms of Zika and who traveled the the Wynwood area during that time should wait at least 8 weeks before trying to get pregnant, the CDC said. Men with symptoms or who have been diagnosed with Zika and who traveled to the area during this period should wait at least six months before trying to get their partner pregnant.
Although most people infected with Zika have no symptoms or only develop mild illnesses, the virus causes an array of severe birth defects, including a condition known as microcephaly.
Scott announced late Friday that the Miami Beach zone was expanded to cover 4.5 square miles because state health department officials have identified five people who have experienced symptoms within one month of each other, three of them in the newly expanded area.
Florida now has at least 93 cases of locally transmitted Zika. State officials credited aggressive mosquito-control measures for stopping the spread in Wynwood, and they said they would redouble efforts in the Miami Beach area.
