“…However, there has been an increase in the number of cases reported in coastal areas of the metropolitan region of Recife, [6][7][8][9] as well as in urban areas of the cities of Belo Horizonte, Salvador and Aracaju. [10][11][12][13] The appearance of cases of the disease in urban areas is not evidence of local transmission of S. mansoni, as it may be the result of infected migrants coming from endemic areas. 6,11,13,14 Considering the existence of individuals infected with S. mansoni living in urban agglomerations with precarious basic sanitation systems, inadequate water supply and presence of the intermediate host, predictive conditions for the establishment of the cycle of this parasite can be identified.…”

Objective: to describe schistosomiasis cases and deaths among residents of the city of Recife, Pernambuco, Brazil, from 2005 to 2013. Methods: this was a descriptive epidemiological study using data from the Mortality Information System (SIM) (2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013) and the Notifiable Diseases Information System (SINAN) (2007)(2008)(2009)(2010)(2011)(2012)(2013); active tracing of the relatives of the dead was undertaken and probabilistic linkage of the databases (2007)(2008)(2009)(2010)(2011)(2012)(2013) was performed using the Reclink program. Results: 297 schistosomiasis deaths were recorded on the SIM system; through active tracing, 130 relatives were contacted and 20.8% autochthony was identified; 388 cases resident in Recife were registered on the SINAN system; through probabilistic linkage, 23 matching records were identified on SIM and SINAN. Conclusion: investigation of deaths showed that some individuals had never traveled outside Recife and progressed to the chronic stage of the disease; 23.8% of the cases registered on SINAN had Recife as the municipality in which infection occurred.

“…Como o local do criadouro já foi foco de esquistossomose e tendo em vista a proximidade de uma favela cujas crianças bricam e jogam bola próximo das valas onde são encontrados os moluscos, podendo eventualmente defecar e entrar em contato com a água, existe o risco de contaminação dos moluscos com S. mansoni. De fato, na zona Sul de Belo Horizonte, no Parque Julien Rien (Figura 1), no bairro Anchieta, ocasionalmente são encontrados moluscos B. glabrata com infecção natural por S. mansoni (Guimarães et al, 1993). Portanto, Belo Horizonte, onde a transmissão da esquistossomose tem sido feita principalmente por B. glabrata em vários bairros, e em pequena proporção por B. tenagophila no lago da Pampulha (Figura 1), corre o risco de ter mais um foco da parasitose transmitida por B. straminea.…”

Esquistossomose: nova ocorrência de Biomphalaria straminea em Belo Horizonte, Minas Gerais

In Belo Horizonte, Minas Gerais, Brazil, the snail Biomphalaria straminea was found in the Pampulha region. Recently the snail was found in ditches in the old Santa Lúcia Reservoir, a now-extinct focus of schistosomiasis transmission by B. glabrata. The snails were collected and examined to verify whether they were naturally infected with Schistosoma mansoni. Negative specimens were used for breeding or infection with the LE strain of S. mansoni from the laboratory and another strain obtained from eggs found in the feces of a schoolchild (VGS) from Belo Horizonte. Among the 1890 snails collected from 1994 to 1995, none were infected with S. mansoni. Among 87 snails collected and exposed to the LE strain, 9 (10.3%) shed cercariae; among 83 snails from F1, and exposed to LE, 10 (12.0%) shed cercariae. Among 88 snails exposed to VGS, 10 (11.3%) shed cercariae. In Belo Horizonte, schistosomiasis is transmitted by B. glabrata and B. tenagophila. However, currently there exists the risk of appearance of a focus in which B. straminea could be the host if prophylactic measures are not taken by the authorities responsible for the construction of a park and lake at that site.

“…In Brazil, the number of reported cases of this disease has been increasing in urban areas, such as Belo Horizonte, Salvador and Fortaleza (Guimarães et al, 1993;Guimarães and Tavares-Neto, 2006). It is estimated that in the north-eastern and south-eastern regions of the country, schistosomiasis affects about 1.3% and 2.4% of the population, respectively, and that 25 million humans are exposed to the risk of contracting the disease in the country (Moh, 2014).…”

Mapping the risk for transmission of urban schistosomiasis in the Brazilian Northeast

This is an analysis of the risk of schistosomiasis transmission in the city of Recife in the Northeast of Brazil based on the number of schistosomiasis cases (Schistosoma mansoni) registered for the period 2007-2017 together with data resulting from active search of breeding sites of the Biomphalaria snail intermediate host. The analyses were performed using Kernel Density Estimation (KDE), SaTScan and Map Algebra methodology using human socio-demographic data and biotic and abiotic data from the snail breeding sites. Investigating 44 breeding sites resulted in a total of 3.800 snails, 31.8% of which were positive for S. mansoni DNA. These data were considered in relation to total of 652 schistosomiasis cases. The KDE showed two high-risk and two medium-risk clusters, while three significant clusters were identified by SaTScan. Combining these data with the Map Algebra methodology showed that all high-risk neighbourhoods had breeding sites with snails positive for S. mansoni. It was concluded that schistosomiasis transmission cannot be controlled without basic sanitation and sewage management in the presence of Biomphalaria snails. The technique of Map Algebra was found to be fundamental for the analysis and demonstration of areas with a high probability of schistosomiasis transmission.
