Figure 1.

Kinetics of IgG (A) and IgM (B) responses among scrub typhus cases. Longitudinal antibody dynamics were modeled from enzyme-linked immunosorbent assay (ELISA)-measured antibody responses using Bayesian hierarchical models. The points are the observed individual antibody concentrations; each point indicates one sample, and samples from a patient with more than one sample are connected with lines. The dark solid line indicates the median for the model-fitted antibody decay concentrations. OD = optical density; OT = Orientia tsutsugamushi.
