Specific situations related to acute schistosomiasis in Pernambuco, Brazil

“…The prevalence and intensity of the infection is subject to cultural practices, specific for each locality or situation and usualy associated to economic, domestic or leisure activities (Barbosa & Barbosa 1998) Historically considered as a rural endemic disease, schistosomiasis is gradually expanding into the coastal regions of the State of Pernambuco due to the exodus of rural workers to the urban areas. This migratory process, caused by poverty in the rural areas, encourages people to go to the metropolitan region of Recife in search of work, medical assistance and education.…”

Análise espacial dos casos humanos de esquistossomose em uma comunidade horticultora da Zona da Mata de Pernambuco, Brasil

“…A previous study performed at this location 15 registered 35.1% of the population infected by S. mansoni. On that occasion, all cases received specific medication for treatment.…”

“…EpiInfo 3.5.1 was used to calculate the minimum sample necessary to obtain results with statistical significance, with a 35% estimated prevalence and a maximum error of 5% for schistosomiasis in the community, based on a previous study 15 . A minimum number of 284 patients was established for a 95% level of confidence.…”

“…The search and identification of potential foci of parasite infections are extremely important to public health, given they can provide prophylactic and educational information to fight the forms of transmission and development of these conditions, mainly in regions where schistosomiasis is historically endemic, such as the Zona da Mata of Pernambuco, where several control strategies been thought of, although no advance has been sustainable enough for its control [14][15][16][17] .…”

Schistosomiasis mansoni in Bananal (State of São Paulo, Brazil): I. Efficiency of diagnostic and treatment procedures

“…Even though a low susceptibility to S. mansoni has been attributed to B. tenagophila, the characteristics of the foci found in Bananal, of which a low estimated density of the worm population is not the least important, give a clear proof Conceição and Coura (1978), Katz (1980) and Barbosa and Barbosa (1998), who remark that the probability of success in the control of this endemic infection increases when the peculiarities of each epidemiological situation are taken into account.…”
