A Case of Dengue Fever With Multiserotype IgG Positivity

Area of Science:

• Tropical Medicine
• Infectious Diseases
• Virology

Background:

• Dengue fever is a significant global health concern, endemic in tropical and subtropical areas.
• It is a mosquito-borne viral illness with increasing prevalence worldwide.

Observation:

• A 52-year-old male presented with severe dengue-like symptoms after traveling to El Salvador.
• Symptoms included high fever, malaise, diarrhea, dizziness, blurry vision, chills, cough, headache, and generalized pain.
• Physical examination revealed petechiae and a positive Rumpel-Leede test, indicating capillary fragility and potential thrombocytopenia.

Findings:

• The patient's clinical presentation was consistent with dengue infection.
• Supportive care, including antipyretics, hydration, and electrolyte management, led to symptom resolution.
• The patient was discharged by day four of treatment.

Implications:

• This case highlights the importance of considering dengue in differential diagnoses for patients with relevant travel history.
• It emphasizes the expanding geographic reach of dengue fever.
• Prompt recognition and supportive management are crucial for favorable outcomes in dengue cases.
