General information about symptoms of Dengue hemorrhagic fever: The symptom information on this page attempts to provide a list of some possible symptoms of Dengue hemorrhagic fever. This symptom information has been gathered from various sources, may not be fully accurate, and may not be the full list of symptoms of Dengue hemorrhagic fever.

List of symptoms of Dengue hemorrhagic fever: The list of symptoms mentioned in various sources for Dengue hemorrhagic fever includes:

Symptoms of Dengue hemorrhagic fever: Dengue hemorrhagic fever is characterized by a fever that lasts from 2 to 7 days, with general signs and symptoms that could occur with many other illnesses (e.g., nausea, vomiting, abdominal pain, and headache). This stage is followed by hemorrhagic manifestations, tendency to bruise easily or other types of skin hemorrhages, bleeding nose or gums, and possibly internal bleeding. The smallest blood vessels (capillaries) become excessively permeable (“leaky”), allowing the fluid component to escape from the blood vessels. This may lead to failure of the circulatory system and shock, followed by death, if circulatory failure is not corrected. 1

During the first few days of illness, dengue hemorrhagic fever (DHF), a severe and sometimes fatal form of dengue, may resemble classic dengue or other viral syndromes. Patients with DHF may have fever lasting 2 to 7 days and a variety of nonspecific signs and symptoms. At about the time the fever begins to subside, the patient may become restless or lethargic, show signs of circulatory failure, and experience hemorrhagic manifestations. The most common of these manifestations are skin hemorrhages such as petechiae, purpura, or ecchymoses, but may also include epistaxis, bleeding gums, hematemesis, and melena. DHF patients develop thrombocytopenia and hemoconcentration, the latter as a result of the leakage of plasma from the vascular compartment. The condition of these patients may rapidly evolve into dengue shock syndrome (DSS), which, if not immediately corrected, can lead to profound shock and death. Advance warning signs of DSS include severe abdominal pain, protracted vomiting, marked change in temperature (from fever to hypothermia), or change in mental status (irritability or obtundation). Early signs of DSS include restlessness, cold clammy skin, rapid weak pulse, and narrowing of pulse pressure and/or hypotension. Fatality rates among those with DSS may be as high as 44%. DHF/DSS can occur in children and adults. 2
