“…Segundo o Ministério da Saúde, no período de 1990 a 2009, houve redução de 90,0% na taxa de internação hospitalar e de 50,0% na taxa de mortalidade associadas à esquistossomose, fato também apontado por Martins-Melo et al 23 , que analisaram o período entre 2000 e 2011. Nesse mesmo período, ocorreu também redução de 60,0% no número de municípios com altas prevalências (> 15%); ainda que muitas localidades rurais tenham mantido elevada prevalência da doença 24 .…”

“…The disease is transmitted by Schistosoma mansoni in the Region of the Americas, and Brazil and Venezuela present the highest endemicity [2, 3]. Between 2.5 and 6 million people are currently estimated to be infected with S. mansoni [4], and 700–800 deaths are reported annually in 19 Brazilian endemic states [5, 6]. A recent systematic review and meta-analysis reported that the prevalence of S. mansoni infection in Brazil varied widely, from 0·1 to 73·1%, based on the Kato-Katz technique [7].…”

Assessment of a Brazilian public policy intervention to address schistosomiasis in Pernambuco state: the SANAR program, 2011–2014

BackgroundBrazil is an endemic country for schistosomiasis in the Latin American and Caribbean countries. Pernambuco is a higher-endemic Brazilian state among the 19 states reporting the disease in the country; schistosomiasis affects 102 (55%) of its 185 municipalities. Our objective was to evaluate the effectiveness of the treatment cycles of the SANAR Program (Plan to Reduce and Eliminate Neglected Diseases) in Pernambuco State in Northeast Brazil.MethodsA cross-sectional population-based study was conducted in 2014 via a household survey in 117 hyperendemic locations in the state of Pernambuco. We compared the schistosomiasis prevalence rates in hyperendemic locations, aggregated by geographical region, before and after the intervention. The dependent variable was a positive stool test result by the Kato-Katz method, and the main exposure variable was the number of treatment cycles (one/two). The covariables were the regions of the state and socioenvironmental, socioeconomic, demographic and behavioral characteristics.ResultsIn all, 12,969 individuals were interviewed, 8932 of whom had stool tests. Of these, 4969 (55.6%) underwent two cycles of collective treatment. Changes in the environmental conditions since 2011 were minimal. Comparison before (2011) and after (2014) treatment showed an average schistosomiasis prevalence of 18.6%, decreasing to 4.1% and 2.0% in locations with one and two treatment cycles, respectively. In 2014, the highest schistosomiasis prevalence was found in the forest area (2.8%), while the lowest was found in the northern region (1.2%) of the state. The adjusted analysis showed a lower occurrence of schistosomiasis in individuals living in areas with two treatment cycles than in individuals from areas with just one cycle (PR 0.65, 95% CI: 0.47–0.89).ConclusionsThe political decision made in Pernambuco to implement the SANAR Program in 2011 greatly impacted the burden of schistosomiasis. This program was effective in reducing the occurrence of schistosomiasis in hyperendemic areas in Pernambuco, with a stronger response in areas with two cycles of collective treatment.

“…Data from World Health Organization (WHO, 2012) reveal that more than 249 million people in 78 countries are infected with Schistosoma mansoni (Sambon, 1907); 7.1 million in the Americas, 95% of which in Brazil (Favre et al, 2012;Martins-Melo et al, 2014). The disease had been catalogued by the Global Plan as one the Neglected Tropical Diseases, and is considered by the World Health Organization (WHO) to be the second most socioeconomically devastating parasitic disease, next to malaria (WHO, 2012).…”

“…The disease had been catalogued by the Global Plan as one the Neglected Tropical Diseases, and is considered by the World Health Organization (WHO) to be the second most socioeconomically devastating parasitic disease, next to malaria (WHO, 2012). Martins-Melo et al (2014) pointed out that from 2000 to 2012 in Brazil, 8756 deaths were related to schistosomiasis (0,07%), representing an annual average mortality of 0.49 deaths/100,000 inhabitants.…”

“…According to Brazilian Health Department (Brasil, 2010), Minas Gerais is one of the Brazilian states with a large endemic area for schistosomiasis, where the higher number of infections has been found in the Northeast and East regions (Kloos et al, 2001;Massara et al, 2008), which comprehend Mata Zone (Lambertucci et al, 1987;Carvalho et al, 1989;Guimarães et al, 2008;Martins-Melo et al, 2014).…”

Irrigation canals in Melo creek basin (Rio Espera and Capela Nova municipalities, Minas Gerais, Brazil): habitats to Biomphalaria (Gastropoda: Planorbidae) and potential spread of schistosomiasis

This study analyzed the presence of Biomphalaria in Melo creek basin, Minas Gerais state, and its relationship to irrigation canals. Seventeen of these canals were used to determine a limnological, morphological and hydrological characterization during an annual seasonal cycle. Biomphalaria samples were sent to René Rachou Research Center/FIOCRUZ for identification and parasitological examination. Six canals were identified as breeding areas for mollusks and in one of them it was registered the coexistence of B. tenagophila (first report to this basin) and B. glabrata species. Results indicated that the low flow rate and speed of water flow were the main characteristics that contributed to this specific growth of the mollusks in the area. These hydraulic characteristics were created due to anthropogenic action through the canalization of lotic areas in Melo creek, which allowed ideal ecological conditions to Biomphalaria outbreak. The results emphasize the need of adequate handling and constant monitoring of the hydrographic basin, subject to inadequate phytosanitary conditions, aiming to prevent the occurrence and propagation of schistosomiasis.Keywords: mollusk, limnology, hydrology, watershed management, Brazil.
