Age distribution of sampled cattle.
Four hundred sixty nine cattle, ranging in age from one year old to sixteen years old, were sampled for serotype-specific FMDV antibodies.

Yearly force of infection by serotype.
Estimates derived by model fitting for the time-varying force of infection (FOI) for SAT1, SAT2, SAT2, type O, and type A inferred for the 16-year period preceding data collection represented by a solid line. The dotted line represents the epidemic threshold R0 = 1; the shaded areas represent estimated FOI that correspond to R0 > 1 and therefore, sustained chains of transmission within the study population. Note that the scale of the y-axis varies across panels.

Model selection and parameterization results for five FMDV serotypes.
Best-fit model results using the catalytic model (for SAT2, SAT3, and type A) or reverse catalytic mode (for SAT1 and type O) with values for the duration of immunity and serotype-specific time-varying forces of infection estimated from serology data.
