Warning Signs and Management of Dengue in Children

Clinical Presentation and Warning Signs

The key warning signs of dengue in children include persistent vomiting, abdominal pain/tenderness, clinical fluid accumulation, mucosal bleeding, lethargy/restlessness, liver enlargement, and rising hematocrit with concurrent thrombocytopenia, according to the American Academy of Pediatrics 1
Dengue typically presents with fever, headache, retro-orbital pain, muscle and joint pain, and rash, as recommended by the Centers for Disease Control and Prevention 2
Warning signs that require immediate medical attention include persistent vomiting, abdominal pain or tenderness, clinical fluid accumulation, mucosal bleeding, lethargy or restlessness, liver enlargement, and rising hematocrit with concurrent thrombocytopenia, as stated by the World Health Organization 1

Acetaminophen/paracetamol is recommended for fever and pain management by the American Academy of Pediatrics 3
NSAIDs and aspirin must be strictly avoided due to increased bleeding risk, as advised by the Centers for Disease Control and Prevention 3
Adequate oral hydration with fluids containing electrolytes is essential, according to the World Health Organization 3
For patients with persistent vomiting, hospitalization for intravenous fluid therapy may be necessary, as recommended by the American Academy of Pediatrics 3

Warning signs typically appear around day 3-7 of illness, coinciding with defervescence, and the presence of any warning sign warrants close monitoring and consideration for hospitalization, as stated by the World Health Organization 1
Early recognition of these warning signs and appropriate management can significantly reduce the case-fatality rate to less than 0.5%, according to the American Academy of Pediatrics 1

The World Health Organization classifies dengue into three categories, including Severe Dengue, which is defined as dengue with severe plasma leakage, severe bleeding, or organ failure 4
