  1. 1. Case presentation on Dengue Fever, Dengue shock syndrome
  2. 2. • Dengue fever also known as breakbone fever, is a mosquito-borne topical disease caused by the dengue virus • Dengue fever, a benign syndrome caused by several arthropod-borne viruses Dengue fever
  3. 3. ETIOLOGY • Vector • Mosquito • Primarily Aedes Aegypti • Most female Ae. Aegypti • Dengue virus ▫ Flavivirus: Single Stranded RNA virus ▫ Serotypes: DEN-1 to DEN-4
  4. 4. Incidence ▫ 2.5 billion people in over 100 endemic countries ▫ 50 million people infected annually with 500,000 cases of DHF and approx 20,000 deaths
  5. 5. Dengue Clinical Syndromes: 1.Undifferentiated fever; 2.Classic dengue fever; 3.Dengue hemorrhagic fever, or DHF; and 4.Dengue shock syndrome, or DSS.
  6. 6. Dengue Fever Classical Dengue fever or Break bone fever is an acute febrile viral disease frequently presenting with headaches, bone or joint pain, muscular pains,rash,and leucopenia
  7. 7. • Dengue hemorrhagic fever is a severe, often fatal, febrile disease caused by dengue viruses. • It is characterized by capillary permeability, abnormalities of hemostasis, and, in severe cases, a protein-losing shock syndrome 4 Necessary Criteria: 1.Fever, or recent history of acute fever 2.Hemorrhagic manifestations 3.Low platelet count (100,000/mm3 or less) 4.Objective evidence of “leaky capillaries:” • elevated hematocrit (20% or more over baseline) • low albumin
  8. 8. Dengue shock syndrome is the fourth clinical syndrome of dengue fever a sever form of Dengue hemorrhagic fever • 4 criteria for DHF • Evidence of circulatory failure manifested indirectly by all of the following: • Rapid and weak pulse • Narrow pulse pressure (< 20 mm Hg) OR hypotension for age +
  9. 9. Pathophysiology
  10. 10. Prevention
  11. 11. Prognosis • Dengue fever < 1% mortality • Dengue hemorrhagic fever approx 2.5% mortality • Primarily children • Dengue shock up to 47% mortality
