Figure 1.
Study site location and household infestation status in 2011.
A. Map of Guatemala showing the location of Comapa and Zapotitlán, Jutiapa. B. Map of Comapa and Zapotitlán showing the presence (grey circles) and absence (white circles) of household infestation of Triatoma dimidiata, and triatomines infected with Trypanosoma cruzi (red circle). No triatomines were collected in the municipality of Zapotitlán. *Because of conflicts between municipalities three communities considered part of Comapa are located outside the map boundary.

Association of triatomine infestation according to person-hour survey and animal ownership as reported by householders, and rodent presence as recorded by rodent surveys.
