Age-specific prevalence of seropositivity for Trypanosoma cruzi infection in Area I residents by ethnic group (a) and observed (black) and predicted (grey line) seroprevalence according to an irreversible catalytic model with a constant force of infection (b) in Pampa del Indio, Chaco. The arrow indicates when the last community-wide insecticide spraying was conducted. Numbers close to data points represent the numbers of humans examined for infection; bars are 95% CI. This figure excludes 18 people from a mixed ethnic background. Multimodel inference analysis provided little support for including an ethnic group in the best models
