INTRODUCTION: This study aimed to determine the prevalence of vertical HIV-1 transmission in the western region of the State of São Paulo, Brazil. METHODS: The study analyzed the medical records of HIV-1-infected mothers and infant pairs living in the municipalities of São Paulo Regional Health Departments DRS II (Araçatuba) and DRS XI (Presidente Prudente). From March 2001 to March 2006, blood samples were collected and referred to the Molecular Biology Unit of the Adolfo Lutz Institute (ALI), Presidente Prudente. HIV-1-RNA viral load was determined by bDNA assay. RESULTS: The number of births (109/217, 50.2%) and vertical HIV-1 transmissions (6/109, 5.5%) that occurred in DRS II was similar to births (108/217, 49.8%) and vertical transmissions (7/108, 6.5%) in DRS XI (p > 0.05). Although 80% (4/5) of the infected children were male in DRS II, while in DRS XI, 75% (6/8) were female, no differences between sex regarding infected and noninfected children in the regions of Araçatuba and Presidente Prudente were verified. The overall vertical HIV-1 transmission rate was 6%. No consistent reduction in the prevalence of vertical HIV-1 transmission occurred over the years. About 20% of mothers did not know the HIV-1 status of their newborns eight months after delivery. CONCLUSIONS: In the present study, MTCT prevalence rates were about 70% higher than those previously determined in the State of São Paulo, with noreduction throughout the period.Furthermore, a significant number of mothers did not know the HIV-status of their newborns eight months after delivery.

In the first half of this century - a period of expanding coffee cultivation - there was a close relationship between the growth of cleared spaces, the domestication of triatomines, and the establishment of Chagas' disease in the state of São Paulo. However, the initiation of control mesuares in 1950 coincided with a period characterized by a progressive reversal of the conditions that had facilitated the establishment of Chagas' disease in the first place. Alterations were taking place in the agricultural environment, rural areas were becoming depopulated, and low-grade housing was being destroyed. Natural transmission of the endemic was interrupted in the mid-1970's, following the elimination of Triatoma infestans from homes. Subsequently, however, a challenge emerged from two extradomiciliary species, Triatoma sordida and Panstrongylus megistus. The invasive character of these species made it necessary to investigate their possible repercussions on human populations and to set up permanent programs of epidemiological surveillance involving direct participation by local populations.
