The percentage of CD69 positive iNKT cells was significantly higher during febrile phase (day -1) (median 3.02%; interquartile range 2.18–20.33%) and defervescence phase (day 0) (7.42%; 3.91–13.23%) compared to 2 weeks after fever subsided (0.50%; 0.13–2.08%) in patients with DF (p<0.05 and p<0.005 respectively) (Figure 2c). The gene discussed is CD69; the disease is dengue disease.
