Introduction: Dengue fever, a mosquito-borne viral disease, is a global health issue affecting people of all ages and both genders. Understanding the demographic, clinical, and immunological characteristics of patients can guide clinical management and prognosis.

Material and Methods: We retrospectively analyzed a cohort of 200 patients diagnosed with Dengue fever. We examined demographic characteristics, hematological and liver function parameters, clinical symptoms, and Dengue IgM and IgG antibody levels.

Results: The mean patient age was 35 years, with a standard error of 0.71 years, suggesting a broad age range of Dengue fever affliction. Among the patients, 55% were male, and 45% were female. Thrombocytopenia was common, with a mean platelet count of 100 x 10^9/L. Hematocrit, AST, and ALT levels were within or slightly above normal ranges. The most common symptoms were fever (90%) and headache (70%). IgM and IgG antibodies had mean levels of 1.65 (SD = 0.84) and 10.25 (SD = 3.12), respectively.
