Based on the clinical symptoms (fever, myalgia, headache, and vomiting), signs (palpable hepatosplenomegaly), and laboratory findings (pancytopenia with deranged liver function tests), dengue fever was suspected in the context of endemicity and seasonality.2 It was subsequently confirmed through positive anti-dengue IgM and IgG antibodies in ELISA. This evidence concerns the gene CD40LG and dengue disease.
