Fig. 2. — Relationships between the three main post-chikungunya syndromes reported among infected subjects aged 15 years and over who declared symptoms at the onset of infection, TELECHIK cohort study, Reunion island, November 2007–May 2008. The percentage in the left upper corner (light pink) accounts for the subjects who recovered. The percentage in the right upper corner (light blue frame) accounts for the ensemble of all long-lasting post-chikungunya disease manifestations. Percentages into the Venn diagram accounts for the proportions of the three long-lasting post-infective syndromes of interest: long-lasting rheumatic musculoskeletal pain (yellow circle and left bottom frame), idiopathic chronic fatigue (green light circle and right bottom frame) and chronic fatigue syndrome-like illness (dark green bottom circle). In light blue are other manifestations remaining to be specified, as sleep disorders (n = 23), memory troubles (n = 20), blurred vision (n = 15), depression (n = 12), attention difficulties (n = 6), hearing difficulties (n = 4) and mood disturbance (n = 3).
