Probabilities of Zika virus RNA clearance according to time after onset of symptoms. Kaplan-Meier estimates (A) and parametric estimates (B) of the Zika virus RNA clearance probability. A table displaying number of individuals at risk of loss of Zika virus RNA detection is provided in panel A. An accelerated failure-time regression model (AFT) with a log-logistic error distribution was used to provide parametric estimates. The medians are indicated for both analyses (A, B) and the 95th percentile is provided for the parametric analysis only (B). Light gray shading denotes 95% confidence intervals. Abbreviation: CI, confidence interval.
