## Clinical Context This patient has **uncomplicated dengue fever** (dengue without warning signs) on day 4 of illness with mild thrombocytopenia (95,000/µL) but no haemorrhagic manifestations, shock, or organ involvement. ## Key Point: **Uncomplicated dengue with platelet count >50,000/µL and no warning signs can be managed as outpatient** with close follow-up and education on danger signs. Hospitalization is reserved for dengue with warning signs or severe dengue. ## High-Yield: Dengue management is **risk-stratified**: - **No warning signs + platelets >50,000/µL** → Outpatient care with daily monitoring - **Warning signs present** (persistent vomiting, abdominal pain, lethargy, bleeding, hepatomegaly >2 cm) → Admit - **Severe dengue** (plasma leakage, haemorrhage, organ failure) → ICU admission ## Clinical Pearl: **Platelet transfusion is NOT indicated** unless platelets <20,000/µL with bleeding, or <50,000/µL with active haemorrhage. Prophylactic transfusion increases thrombotic and fluid overload risk [cite:WHO Dengue Guidelines 2009]. ## Management Algorithm for This Case ```mermaid flowchart TD A[Dengue confirmed, Day 4 fever]:::outcome --> B{Warning signs present?}:::decision B -->|Yes| C[Admit to hospital]:::action B -->|No| D{Platelet count?}:::decision D -->|<50,000/µL| E[Admit for monitoring]:::action D -->|≥50,000/µL| F[Outpatient management]:::action F --> G[Daily CBC, LFT, rehydration counselling]:::action F --> H[Educate on warning signs]:::action H --> I[Return if bleeding, shock, severe abdominal pain]:::action ``` ## Counselling Points for Discharge - Oral rehydration (isotonic fluids, electrolyte solutions) - Paracetamol for fever (avoid NSAIDs and aspirin) - Return immediately if: persistent vomiting, abdominal pain, bleeding, lethargy, restlessness - Daily follow-up for CBC (critical phase is days 3–7) [cite:Park 26e Ch 14, WHO Dengue Clinical Management 2012]
