Tentativa de avaliação do programa especial de controle da esquistossomose (PECE) no Estado da Paraíba, Brasil

Epidemiological and control aspects of schistosomiasis in Brazilian endemic areas

“…However, all of them show a reinfection trend and an increase of parasite load after a time, when there is therapeutic interruption, being more intense in children than in adults, indicating that therapy alone is not able to interrupt transmission. This fact was very well demonstrated during an evaluation attempt of Special Schistosomisis Control Program (Pece), in Paraíba, after ten years of program installation (Coura et al 1987).…”

A comparative cross-sectional study on the prevalence and morbidity of schistosomiasis in a community in northeastern Brazil (1979-2010)

“…Coura and Camillo-Coura (1980) and Coura et al (1983, 1984, 1987, 1992) conducted studies on the morbidity, evolution and control of schistosomiasis in areas of MG, SE and PB. Following the master’s degree dissertations and PhD thesis of Conceição (1976, 1985) in Capitão Andrade, MG, and of Mendonça (1982) in Alhan- dra, PB, several studies were conducted by Conceição and Borges-Pereira (2002), Conceição et al (2007) and Conceição and Coura (2012) on the prevalence of morbidity, evolution and the response to specific treatment of schistosomiasis in rural areas in MG.…”

In PB, in addition to the study conducted by Mendonça (1982) in Alhandra, Coura et al (1987) conducted an evaluation of the Schistosomiasis Control Program in all areas covered by the program in that state, including Alhandra. With the dissertation of de Melo (2012), which formed a basis for the present study, 33 years of observations of schistosomiasis have now been conducted in Alhandra.…”

“…Studies conducted by Coura et al (1983, 1984, 1987, 1992), Coura and Amaral (2004) and Conceição and Coura (2012) have demonstrated the prevalence and morbidity of schistosomiasis in various areas of Brazil. In a hospital study, Coura et al (1982) showed that of 4,652 patients, 12.82% had the hepatosplenic form (Type III) and 87.18% presented the hepatointestinal form (Type II).…”

Schistosomiasis control in Brazil

“…It must be also pointed out that the great majority of the studies performed in specific endemic areas, by different researchers in Brazil, consistently find significant decrease on prevalence and on incidence of schistosomiasis, when control measures (chemoterapy and/or molluscicide) are repeatedly used for a number of years (Katz 1980, Coura et al 1987, Coura Filho et al 1992, Katz 1992, Lima e Costa et al 1993.…”
