After four area cases of Dengue fever, the Florida Department of Health in Martin County has issued a health alert.
The most recent case of the mosquito-borne illness was confirmed in the Rio neighborhood of Jensen Beach in Martin County.
Last week, a total of three cases were confirmed. Two of the people affected live in Martin County, while the third resides in St. Lucie County.
Health officials said after an investigation they believe all of the cases are related from mosquitoes in the Rio area.
Mosquito Control in Martin County is continuing to inspect and treat properties in the affected areas.
Residents are urged to drain standing water to stop mosquitoes from multiplying. Also, cover your skin with clothing or use repellent while outside.
Dengue fever is transmitted to humans by the bite of an infected mosquito, not person to person. The disease is rare in the U.S., but it's estimated there are over 100 million people affected worldwide each year.
