The dynamics process of Mansonic Schitomiasis endemization is multifactorial, which sometimes retards it’s installation process, but also difficult the control of epidemiological surveillance. The Geo-technologies have brought contributions to the public health, creating thematic maps that make easier understand of dynamic population at space used, and their interrelationship with the water resources and with the sickness process. The proposal of this work was to identify through spatial analysis the eco-epidemiological factors related with the Mansonic Schitosomiasis endemization. It was achieved a descriptive study in two coverage areas from Family Health Strategy, Carananduba and Furo das Marinhas, In Mosqueiro District, Belém-PA, between 2010 and 2012, using geoprocessing Techniques like: Remote Sensing and Geographic Information Systems (GIS), through the tools: ERDAS 8.3.1 and ENVI 4.5, for classification of these satellites images, with the variables: Soil, vegetation cover and hydrography; The Global Positioning System (GPS) for georreferencing at study area and capturing collecting points of breeding sites; and ARCGIS 9.3.1 for manipulation and teatring of the Geographic Data Banks and Kernel estimation for identification of risk zones about high resolution satellite images and cartographic bases. Were analyzed, also, environmental and ecological data through geoprocessing techniques. The geo-technologic tools producing thematic maps of Family Health Strategic abrangency, the work routes, environmental classification, and the localization of breeding sites that generating seven agglomerated Kernel points that identified the risk zones of transmission aggravating in 3 boroughs of Carananduba Zone. This zone has been presenting antrophic characteristics due disordered human occupation and hydro siltation collections. The Furo das Marinhas area still keeps native forest and great quantity of hydro collections yet and not being found Biomphilaria. In both studied areas the structure of sanitation is insufficient, and isn’t still there focus active of transmission from Mansonic Schitosomiasis. However, could be a great vulnerability in a short time to happen this incidence at Caranaduba area. So, the geo-technologies applied have enabling a geographic information system that made feasible the diagnostic of risk on the process of Mansonic Schitosomiasis Endemization in more than one location in Para.

Avaliação da vulnerabilidade do potencial de endemização da esquistossomose mansônica no Distrito de Mosqueiro Belém, Pará
(Universidade Federal do Pará, 2014) PINTO, Sônia Claudia Almeida; PINHEIRO, Maria da Conceição Nascimento; http://lattes.cnpq.br/6353829454533268; BICHARA, Cléa Nazaré Carneiro; http://lattes.cnpq.br/2161704040280760
Schistosomiasis mansoni (SM) is an endemic parasitic disease that occurs in at least 74 countries with illness of 25 million people, including Brazil. It is related to socioeconomic and environmental factors, with emphasis on migratory movements that contribute to the spread of this disease. In northern Brazil only the state of Para has focus of this disease, the main in the city of Belem.The urban sprawl through the occupation of peripheral areas of the metropolitan area of Belem has generated significant social and environmental impacts, reaching areas of environmental preservation.From an ecosystemic perspective, the study assessed the possibility of expansion of SM in the insular area of the one administrative districts of Belem, in Mosqueiro (DAMOS), where there was the environmental characterization, malacological, parasitological and population surveys. Georeferencing techniques were used for spatial analysis of the study area, interview questionnaire at home and collection of material for parasitological examination. The approach adopted for determining the sample size calculation was based on the territory coverage of the family health strategy of the Belem Municipal Health Department. Thus, was realized the zoning of the study area, where Biomphalaria sp. breeding places were found. And was adopted a 50m radius buffer (north, south, east, west), from each breeding. Inside this area size, with the help of GPS technology, has set up a sample of 491 households with an estimate of 5.31 residents per household, with the exclusion of closed or abandoned households obtained the sample of 283 households for visitation with 421 participants. It was necessary to create the schistosomiasis vulnerability index (SVI) for better information with regard the interpretation of the data. The results showed that the DAMOS presents all environmental and population characteristics of the different endemic areas of Brazil; the malacological survey identified 30 breeding of planorbids; presence of the species B. straminea not infected with S. Mansoni; very low sewage network coverage, water and increase the migratory process in disordered occupation areas with populations from endemic areas for SM.The majority of study participants reside in areas considered of medium vulnerability, however 16% are in areas of high vulnerability; the area of Carananduba was considered the highest susceptibility and increased risk potential for entry of SM in Mosqueiro district.The spatial analysis of vulnerability to schistosomiasis in the study area, has led not only support the hypothesis of endemicity of SM in DAMOS, but to show where the first outbreak may occur, what and where the major risk factors are.This study may help in the management processes in public health with the implementation of preventive measures of health education, epidemiological and environmental surveillance.

Some foci of transmission of schistosomiasis are installed in Para State, with the possibility of permanent expansion by major migration flows through the economic and social demands in the region. It was proposed to reassess the epidemiological situation of schistosomiasis transmission in this village of Fordlandia, the city of Aveiro, PA, where it was established in 1951 as a result of intense migration appreciation for the extraction of rubber, as the first indigenous Amazonian focus, being considered extinct for several years. The study was conducted between September and November 2012, involving 204 individuals of households served by Strategy Community Health Workers in the District of Fordlandia, PA, submitted to parasitological survey by the Kato-Katz (one sample per capita, processed 3 blades) with description of the socio-demographic profile through interviews to identify the environmental conditions of peridomicile, housing, sanitation, presence of collections hydro, type and form of contact with them, which would be inserted possible risk factors for transmission . It was found that the majority are women (54%), with more than 20 years (56%), especially students and farmers (32% and 26%), residents in the town of Fordlandia (52%) for months or years (64 %). Although environmental conditions, housing and sanitation remain the similarity of the season's activity focus of schistosomiasis in the district of Fordlandia-PA was not identified no cases of schistosomiasis considering all coproscópicos tests negative for eggs of S. mansoni, possibly for this location this time was not affected by the entry of migrants infected by this worm, allowing the restoration of the cycle in place. The dispersal of Biomphalaria snails in the Amazon floodplain, plus the intensification of migratory networks, requires constant vigilance in the region as the expansion and development of future outbreaks of transmission of schistosomiasis, including the reemergence of outbreaks now extinct like Fordlandia-PA.

The Schistosomiasis (MS) is a parasitic infection with a wide geographic distribution that cause important economic and public health implications. This grievance is installed in Brazil since colonial times and remains in all geographic regions, particularly in the northeastern of Brazil. This report shows to be a quantitative, descriptive observational epidemiological research approach across the board, created by active search of secondary data on the prevalence of MS in the state of Maranhão and its regional health from 2007 to 2011, based on data Historic cases reported to the Information System of the Schistosomiasis Control Program and the National Disease Notification Service. The results showed that MS is declining in Brazil, from where 2007 to 2011; most of these are concentrated in the Southeast, with xxx the study period, followed by the Northeast with xxx cases. However, in the northeast is that MS stands for stability and the southern region where there is the lowest recorded levels. The state of Maranhão accumulated more cases of MS in this period than the north, south and center-west regions. We observed two pieces of information regarding the total number of cases in the Maranhão according to base consulted, with 18,884 cases reported by SISPCE \ SINAN and 317,661 by the PCE. In this state the picture remains, but with a tendency to decline as well, focusing on cases of Maranhão marshland region. Among its 19 regional health in 15 case reports were made, predominantly in the eastern St. Louis (129,999), Bacabal (67,735), total years studied. Empress was no increase in the number of cases of 1.63 in 2009 to 10.99 in 2011, which was attributed to the acceleration of, especially migratory sociodemographic and health problems. The analysis shows that the parasitic load Maranhao remains low to medium endemicity in most cases eliminating from 1 to 4 eggs/g of faeces. Thus, this study shows that MS whilst under control in Brazil, Northeast and Maranhão, needs to be better controlled, which depends directly improving the structural conditions of life of its inhabitants.
