Florida health officials reported four additional cases of locally acquired dengue fever in Miami-Dade County in the week ending December 24.
That brings total cases in the county to 59 this year and 63 statewide. In addition to Miami-Dade County, four cases have been reported this year in Collier, Broward (2), and Volusia counties.
All of the original dengue fever reported in the United States was from Florida this year, according to the Centers for Disease Control and Prevention.
There have also been 525 cases of locally acquired dengue fever reported in Puerto Rico.
In addition to local transmission of dengue in Florida, more than 800 cases of travel-related dengue have been reported, with ten cases meeting criteria for severe dengue (dengue shock syndrome) [DSS] or dengue hemorrhagic fever [DHF]).
More than 1,000 travel-related cases have been reported nationwide.
Dengue is a viral infection transmitted by the bite of an infected mosquito. There are four closely related but antigenically different virus serotypes that can cause dengue (DEN1, DEN 2, DEN 3, DEN 4).
Dengue fever (DF) – characterized by the sudden onset of high fever, severe headache, pain behind the eyes, and muscle and joint pain. Some may also experience a rash and varying degrees of bleeding from different parts of the body (including the nose, mouth, gums, or skin bruising). Symptoms can vary from dengue fever (DF) to the more serious dengue hemorrhagic fever (DHF).
Dengue hemorrhagic fever (DHF) – is a more severe condition, seen only in a small percentage of those infected. DHF is a typical disease characterized by three stages; febrile phase with persistent, high fever that usually lasts less than 7 days; The critical phase (plasma leakage) lasting 1-2 days usually appears when the fever has gone down, leading to shock if not detected and treated early; The convalescent phase lasts 2-5 days with improved appetite, bradycardia (slow heart rate), convalescent rash (white spots in a red background), often accompanied by general pruritus (more severe in the palms and soles), and diuresis (increased urine output). urine).
Dengue shock syndrome (DSS) – Dengue shock syndrome is a serious complication of dengue infection and is associated with a high mortality rate. Acute dengue occurs as a result of a secondary infection with a different serotype of the virus. Increased vascular permeability, along with myocardial weakness and dehydration, contributes to shock, leading to multiple organ failure.
