Miami Neighborhood Declared Free of Zika Transmission

"We encourage people not to let down their guard," said the CDC's Tom Frieden.

— -- The Miami neighborhood where a local outbreak of Zika was first detected has been declared free of ongoing Zika transmission.

The first locally-acquired Zika cases in the Wynwood neighborhood of Miami were reported in July. The neighborhood has been at the center of public health efforts to stop the virus from spreading in the U.S. At least 79 people have been reported to be infected via local transmission in Florida since the outbreak started.

Officials used both aerial and other forms of insecticide spraying to try and kill the Aedes aegypti mosquito that is responsible for nearly all of the virus transmission. The disease can also be spread through sexual contact.

While the Wynwood neighborhood has been declared Zika-free, the outbreak remains ongoing since transmission and additional cases have been reported in Miami Beach.

"We could see additional cases," said Frieden. "People living in or visiting Miami-Dade County, particularly pregnant women, are encouraged to continue to take steps to prevent mosquito bites and to follow guidelines for preventing sexual transmission.”

Scott called on Congress to pass a federal bill to help fund actions to prevent the Zika virus from spreading.
