↵a CI, confidence interval.

↵b Data represent results from bivariate comparisons.

↵c In conditional logistic regression analyses, odds ratios were as follows: ZIKV (

*P*= 0.030; odds ratio, 4.0 [95% CI, 1.1 to 14.1]) and CHIKV (*P*= 0.084; odds ratio, 2.8 [95% CI, 0.1 to 9.2]).↵d Data were calculated using χ

^{2}tests and Fisher’s exact tests when any cell count was below 5. Bold type denotes statistical significance.
