OR, odds ratio; CHIKV, Chikungunya virus. All estimations and P-values are weighted by the sampling scheme. All subjects had joint or muscle pain at disease onset. †Joint or muscle pain with at most two of the three following conditions: fever, six or more localisations of arthralgias, or at least four other symptoms; ‡fever and six or more localizations of arthralgias and at least four other symptoms.
