Effects of host age on the average infection duration. The average duration of clonal infections is shown against the midpoint of each age group and compared across clearance models. Lower AIC values indicate a better fit to the data. All models qualitatively agree with respect to the age pattern: an initial increase in duration during childhood, a sudden drop around the time of puberty, and no further decrease thereafter. The best-fitting Weibull model estimates that average duration remains constant in adults at ca. 80 days, even after decade-long exposure. Both the non-monotonic changes during childhood and adolescence as well as the absence of a change in adults are consistent with NAI not acting to shorten infections.
