Small, scattered settlements made up of well-dispersed houses located along four Creeks (SL = São Luiz I, P = Palmital, R = Roque, and U = Ubá) in the study area.
Note: At 7 months, seroprevalences were calculated for the follow-up group that was available for survey. At 10 and 15 months, seropositivity rates were calculated for the original follow-up group plus new canines that had moved into the area and remained there for at least 3 months.
