Dengue Fever

Dengue fever is a systemic viral illness transmitted by Aedes mosquitoes. It is characterized by high fever, severe arthralgia, and myalgia, earning the historical moniker "breakbone fever." While often self-limiting, it can progress to life-threatening hemorrhagic manifestations and circulatory collapse.

Dengue is caused by any of the four distinct serotypes of the Dengue virus (DENV-1 through DENV-4), belonging to the Flaviviridae family. Transmission occurs via the bite of infected Aedes aegypti or Aedes albopictus mosquitoes.

Following inoculation, the virus infects dendritic cells and macrophages. The subsequent release of cytokines ("cytokine storm") increases vascular permeability. In secondary infections, antibody-dependent enhancement (ADE) occurs, where non-neutralizing antibodies from a previous infection facilitate viral entry into cells, leading to increased viral load and severe systemic inflammation.

Endemic in over 100 countries across tropical and subtropical regions. Approximately 3.9 billion people live in endemic areas, with an estimated 390 million infections annually. All age groups are susceptible.

Living or traveling to tropical endemic areas, lack of mosquito control, urbanization, climate change (rising temperatures), and secondary infection with a heterologous DENV serotype.

A. Early Symptoms

• Sudden high-grade fever (up to 104°F)


• Severe retro-orbital pain


• Headache B. Common Symptoms


• Myalgia (muscle pain)


• Arthralgia (joint pain)


• Maculopapular rash


• Nausea and vomiting C. Advanced Symptoms


• Mucosal bleeding (epistaxis, gingival)


• Persistent vomiting


• Severe abdominal pain D. Emergency Symptoms


• Rapid pulse, hypotension


• Respiratory distress


• Massive internal hemorrhage


• Altered mental status

Fever, tachycardia, facial flushing, petechiae, hepatomegaly, and a positive tourniquet test (petechial formation).

A. Clinical Assessment: Recognition of fever + warning signs.
B. Laboratory Testing: NS1 antigen (early), IgM/IgG ELISA (late), PCR.
C. Imaging Studies: Ultrasound to assess for plasma leakage (pleural effusion, ascites).
D. Functional Tests: N/A.
E. Biopsy Findings: N/A.
F. Genetic Testing: Not used for diagnosis.
G. Differential Diagnosis: Zika, Chikungunya, Malaria, Leptospirosis, Typhoid.

Test Name: NS1 Antigen Test
Type: Blood Test
Purpose: Early detection of DENV
Expected Findings: Positive
Interpretation: Acute infection Test Name: CBC with Differential
Type: Blood Test
Purpose: Monitor severity
Expected Findings: Thrombocytopenia, leukopenia, hemoconcentration
Interpretation: Indicates plasma leakage risk

Chest X-ray/Ultrasound: Used to detect pleural effusions or ascites, which are clinical hallmarks of severe plasma leakage.

• Chikungunya: Features more severe, persistent joint pain.
• Malaria: Usually manifests with cyclical fevers and rigors; confirmed via blood smear.
• Zika: Characterized by mild fever, conjunctivitis, and rash.

Dengue shock syndrome, organ failure (liver, kidney), severe hemorrhage, myocarditis.

A. Lifestyle Modifications: Bed rest, hydration.
B. Preventive Measures: Vector control (nets, repellents, eliminating standing water).
C. Medical Treatment: Supportive care, acetaminophen for fever. Avoid NSAIDs (aspirin, ibuprofen) due to bleeding risk.
D. Surgical Treatment: N/A.
E. Interventional Procedures: Fluid resuscitation.
F. Rehabilitation: Physical therapy for chronic fatigue.
G. Emergency Management: Intravenous fluids, blood transfusion for hemorrhage.

Good for classical dengue with proper hydration. Mortality for untreated dengue shock syndrome can exceed 20%, but drops to <1% with timely fluid management.

Mosquito avoidance, vaccines (e.g., Dengvaxia in seropositive individuals), public health vector control.
