Residents of Martin and St. Lucie counties are being urged to take precautionary measures against mosquito-borne illness after three cases of locally acquired dengue fever were confirmed in those counties, according to the Florida Department of Health in Martin County.

The affected individuals had no history of recent international travel. An investigation concluded that exposure may have come from local mosquitoes in the Rio neighborhood near Jensen Beach. Dengue Fever is transmitted by the bite of an infected mosquito. T

he most common symptoms of denque fever include high fever, severe headache, joint and bone pain and rash.

Health officials said that this is the second dengue case in Martin County. The county’s only previous case was contracted by a Port Salerno resident in August 2011. There have been no previous locally acquired cases in St. Lucie County.
