Managing Seasonal Dengue & Viral Fever: When to Consult a Medicine Specialist in Khulna

Understanding Seasonal Dengue in Southwestern Bangladesh

During the monsoon and post-monsoon months, dengue viral infections transmitted by *Aedes* mosquitoes spike significantly across Khulna, Jessore, and Satkhira. While most dengue cases resolve with symptomatic care, severe dengue (Dengue Hemorrhagic Fever) requires rapid specialist intervention.

Critical Phases of Dengue Fever

**Febrile Phase (Days 1–3):**

High fever (103°F–105°F), severe retro-orbital eye pain, joint and muscle aches (breakbone fever), and mild flushed skin.

*Action:* Paracetamol only (avoid aspirin, ibuprofen, or NSAIDs as they increase bleeding risks). Complete Blood Count (CBC) and Dengue NS1 Antigen test.

**Critical Phase (Days 4–6):**

The fever often drops, leading patients to falsely believe they are cured. **However, this is when plasma leakage and platelet drops occur.**

*Warning Signs:* Severe abdominal pain, persistent vomiting, mucosal bleeding (bleeding gums, nosebleeds, black stools), extreme fatigue or restlessness.

**Recovery Phase (Days 7–10):**

General appetite returns, fluid resorption stabilizes, and platelet counts rebound naturally.

Essential Laboratory Monitoring

**Platelet Count:** Monitored daily or alternate days during the critical phase.

**Hematocrit (HCT):** The most accurate indicator of plasma leakage and hemoconcentration. A rising HCT combined with falling platelets warrants immediate intravenous fluid therapy under specialist supervision.
