Observed and predicted host infectiousness, with 95% confidence intervals (shaded areas around solid blue line), according to bloodstream parasite loads in T. cruzi-infected domestic and sylvatic mammals, at Pampa del Indio 2008–2017 and Misiones 2011. Hosts with zero parasite load were pooled with those exhibiting 0.01 Pe/ml. a Model 1, b Model 2, c logistic model for domestic animals, d Model 1 for sylvatic hosts. Symbols:  + represents humans; open square, cats; filled circle, dogs; filled triangle, Dasypus novemcinctus (9-banded armadillo); open circle, Didelphis albiventris (white-eared opossum)
