Characteristics of infection were studied in a rural area of the eastern plains of Colombia. Using enzyme-linked immunosorbent assay and indirect fluorescent-antibody tests, the infection was determined in 11.6% of the inhabitants of 142 dwellings. During 6 months of community surveillance, in 42.3% dwellings, 609 triatomines were collected (597 and seven, three, one, and one of , , , and , respectively). was found in 80% peridomiciliary palms examined with baited traps, and its infection with was 30% and 38.5% in dwellings and palms, respectively. was isolated in five of 35 triatomines and in one of 24 dogs. The blood of domestic and wild animals was identified in triatomines collected in the intradomicile and in palms. These results support the extension of the wild cycle of to human dwellings and the characterization of a new scenario for transmission in Colombia.
