U.S State of Florida health officials are tripling the local Zika's transmission area in Miami Beach, the CNN quoted on Saturday Gov. Rick Scott as saying. 
The zone, which had been limited primarily to South Beach, has expanded north, bringing the total affected area to around 4.5 square miles, a news release from the governor’s office said. 
The Florida Department of Health said five people -- two males and three females -- in the expanded area have experienced symptoms within a month of each other.
