An analysis of the impact of the Schistosomiasis Control Programme in Brazil

“…Thirty years after the introduction of the PCE, it has become obvious that, wiping out schistosomiasis from the country is a huge challenge. Several reasons which account for this difficulty have been dealt with in other papers (Coura & Amaral 2004). At this point, it is worth mentioning two as yet insurmountable technical problems.…”

Spatial analysis for the identification of risk areas for schistosomiasis mansoni in the State of Sergipe, Brazil, 2005-2014

“…The endemic control programs, even instrumented with effective technologies, have not achieved efficiency in their actions because they are making use of a centralized logic that is interventionist, medicalized and standardized for all endemic areas (30) . As much as there are limitations and challenges, SISPCE is a breakthrough in the monitoring and surveillance of schistosomiasis, requiring continuity of action by the municipalities and the use of spatial analysis of cases of schistosomiasis to estimate the risk of disease transmission, set priorities and deepen the analysis of the environment, parasitic infections and the definition of preventive measures.…”

Biomphalaria tenagophila potencial vector of Schistosoma mansoni in the Paraná River basin (Argentina and Paraguay)

“…Foci of active transmission of schistosomiasis have appeared in Brazil in areas till then free from the disease, with serious difficulties for the control (Coura & Amaral 2004). Between 1981 and 1991, the endemia reached the locality from São Francisco do Sul and Jaraguá do Sul in the southeast, in the state of Santa Catarina (Bernardini & Machado 1981, Espinola et al 1992) and B. tenagophila was the natural intermediate host.…”
