Dengue fever is a viral illness spread by mosquitoes, most commonly in tropical and subtropical regions. It can cause flu-like symptoms, and in some cases, can develop into a severe and life-threatening condition. Early recognition and proper management are crucial for preventing severe complications.
Dengue fever is a systemic viral infection caused by four serotypes of the dengue virus (DENV-1, DENV-2, DENV-3, DENV-4), transmitted by Aedes mosquitoes. It presents with a wide spectrum of illness, ranging from asymptomatic infection to severe dengue, characterized by plasma leakage, hemorrhage, or organ impairment.
| Condition | Distinguishing Feature |
|---|---|
| Chikungunya Fever | More pronounced and persistent joint pain, often with swelling, and less frequently associated with hemorrhagic manifestations. |
| Zika Virus Infection | Milder symptoms, often with conjunctivitis and a characteristic rash that may appear earlier. Less risk of severe disease. |
| Malaria | Cyclical fever patterns, chills, and rigors. Diagnosis confirmed by peripheral blood smear or rapid diagnostic tests. |
| Influenza | Respiratory symptoms are more prominent. Dengue typically lacks significant upper respiratory tract involvement. |
| Leptospirosis | Can present with fever, myalgia, and headache. Jaundice, conjunctival suffusion, and renal involvement are more common in leptospirosis. |
| Typhoid Fever | Gradual onset of fever, abdominal pain, and constipation or diarrhea. Rose spots may be present. Blood cultures are diagnostic. |
Management of dengue fever is primarily supportive, focusing on fluid resuscitation to prevent or manage plasma leakage and shock. Careful monitoring for warning signs of severe dengue is essential, with prompt escalation of care for patients exhibiting these indicators. Antipyretics like paracetamol are recommended, while NSAIDs should be avoided due to increased bleeding risk.
