Higher frequencies of CD8⁺ T cells expressing CD69, Interleukin‐17A (IL‐17A), IL‐10 and IL‐10R are found in patients with acute and chronic chikungunya disease (CHIKD). Percentage of CD69 (a), IL‐17A (b), IL‐10 (c) and IL‐10R (d) from healthy individuals (white bars), acute phase patients (black bars) and chronic phase patients (striped bars) was measured ex vivo. Bars represent the mean ± standard error for each group. Means were compared using Student's t‐test and differences were considered significant when P < 0·05. *P < 0·05, **P < 0·005 and ***P < 0·0001.
