A Case of Dengue Fever With Multiserotype IgG Positivity.

Dengue fever is a rapidly spreading mosquito-borne viral disease, increasingly endemic in tropical and subtropical regions. This case report details the clinical presentation of a 52-year-old male who developed severe symptoms shortly after returning from a two-week trip to El Salvador, an area known for dengue endemicity. The patient presented with a five-day history of high-grade fever, malaise, diarrhea, dizziness, and intermittent blurry vision, accompanied by chills, dry cough, headaches, and generalized pain.
