In patients with DHF, the percentage of CD69 positive iNKT cells was also higher during febrile phase (day -1) (27.40%; 17.20–36.80%) and defervescence phase (10.00%; 5.26–22.70%) when compared to 2 weeks after fever subsided (0.23%; 0.00–0.57%) (p<0.0001 and p = 0.0001, respectively) (Figure2d). This evidence concerns the gene CD69 and Dengue hemorrhagic fever.
