Retracing Micro-Epidemics of Chagas Disease Using Epicenter Regression

Figure 2

The expected percent of study participants infected over each calendar year back to 1980.

A. The expectation for models with 2,4,6,8 and 10 epicenters; lines are shaded according to the number of epicenters (2 epicenters-light grey, 10 epicenters = black). B. A boxplot showing the median and credible intervals for the posterior estimates from the best-fit four-epicenter regression model. Chagas disease is a lifelong infection; infected individuals are assumed to remain seropositive through their lifetimes.
