In addition, DENV-NS3 specific T cells of 12.9% of those with mild/sub clinical dengue infection produced granzyme B only, whereas granzyme B only producing DENV-NS3 specific T cells were not detected in any of those who were hospitalized due to dengue (p = 0.02, odds ratio = 0.08, 95% CI 0.004 to 1.4). Here, KRAS is linked to dengue disease.
