[Infestation by triatomines in rural settlement and resettlement areas the Region of Pontal do Paranapanema, State of São Paulo].
This study had the aim of assessing the characteristics of triatomine infestation in human dwellings in rural settlement and resettlement areas with regard to the time when infestation began. We analyzed data relating to 48 triatomine surveys carried out in 105 settlement areas and six resettlement areas in the region of Pontal do Paranapanema between January 1984 and June 2005. Among the 16 surveys in settlement areas, seven (43.8%) had positive findings, all of them in communities established eight or more years previously. Among the 32 surveys in resettlement areas, 23 (71.9%) had positive findings, all of them in communities established for periods shorter than eight years. Since the inhabitants of such communities frequently move, the need for constant vigilance to detect any cases of infestation by vector triatomines in new settlements cannot be overemphasized.
