DENGUE HEMORRHEGIC FEVER

      






Four totally different dengue viruses have been shown to lead to dengue hemorrhagic fever.
Dengue hemorrhagic fever occurs when somebody catches a special kind dengue virus when becoming infected by an additional one sometime prior to. Previous immunity to a special dengue virus kind plays a crucial role during this severe disease. Worldwide, greater than 100 million cases of dengue fever occur annually. A little variety of those develop into dengue hemorrhagic fever.
Most infections inside the United States are brought in from other countries. It's potential, however uncommon, for any traveler who has got returned towards the United States to pass the infection to a person who has got not traveled. Risk factors for dengue hemorrhagic fever embrace getting antibodies to dengue virus from previous infection and becoming younger than 12, female, or Caucasian.
Early symptoms of dengue hemorrhagic fever are similar to those of dengue fever, however when many times the patient becomes irritable, restless, and sweaty. These symptoms are followed using a shock -like state. Bleeding may seem as small spots of blood upon the skin (petechiae) and larger patches of blood below the skin (ecchymoses). Minor injuries may lead to bleeding. Shock may lead to death. When the patient survives, recovery begins following a one-day crisis era.
Early symptoms embrace :
Decreased appetite
Fever Headache
Joint aches
Malaise
Muscle aches
Vomiting
Acute phase symptoms embrace :
Restlessness followed by : Ecchymosis
Generalized rash
Petechiae
Worsening of previously symptoms Shock-like state Cold, clammy extremities Sweatiness (diaphoretic)
A physical examination may reveal :
Enlarged liver (hepatomegaly)
Low blood pressure
Rash Red eyes
Red throat
Swollen glands Weak, rapid pulse Tests may embrace :
Arterial blood gases Coagulation studies Electrolytes Hematocrit Liver enzymes Platelet count Serologic studies (demonstrate antibodies to Dengue viruses) Serum studies from samples taken throughout acute illness and convalescence (improve in titer to Dengue antigen) Tourniquet check (leads to petechiae to type below the tourniquet) X-ray from the chest (may demonstrate pleural effusion) As a result of Dengue hemorrhagic fever is caused using a virus for that there isn't any known cure or vaccine, the only real remedy usually is to deal with the symptoms.
A transfusion of recent blood or platelets can correct bleeding problems Intravenous (IV) fluids and electrolytes will also be designed to correct electrolyte imbalances Oxygen therapy can be had the need to deal with abnormally low blood oxygen Rehydration along with intravenous (IV) fluids is usually essential to deal with dehydration Supportive care inside an intensive care unit/environment Along with early and aggressive care, most patients recover from dengue hemorrhagic fever. But, half untreated patients who get into shock don't survive.
