Epidemiological profile of malaria in a rural community in the Amazon, Mato Grosso State, Brazil, 2011.

Background: More than 95% of malaria transmission in Brazil occurs in the Legal Amazon Region, which in 2010 recorded around 333,429 cases reported in the Epidemiological Surveillance Information System-Malaria (Sivep_malaria), presenting an annual parasitic incidence (IPA) of 13.1 cases/1000 inhabitants.

Methods: This was a descriptive study that measured the community prevalence of Plasmodium infection and its relationship with land use in Três Fronteiras District, Colniza Municipality, Mato Grosso State.

Serological study on toxoplasmosis in the Haliti-Paresí community of the Utiariti indigenous territory, Campo Novo do Parecis, Mato Grosso, Brazil.

is the etiological agent of toxoplasmosis, a widespread zoonosis that affects several homeothermic animals, including humans. This disease causes serious health problems, such that 10% of infected individuals develop clinical manifestations. Some studies on indigenous human populations have indicated variations in seroprevalence from 10.

[Congenital defects in the cities with high use of pesticides in the state of Mato Grosso, Brazil].

Mato Grosso is the largest agricultural producer and the largest national consumer of pesticides in Brazil. Maternal exposure to pesticides in the periconceptional period has been associated with increased risk of congenital malformations. This article aims to analyze the association between the use of pesticides and congenital malformations in cities with highest exposure to pesticides in Mato Grosso.

Geographic information systems and logistic regression for high-resolution malaria risk mapping in a rural settlement of the southern Brazilian Amazon.

Background: In Brazil, 99% of the cases of malaria are concentrated in the Amazon region, with high level of transmission. The objectives of the study were to use geographic information systems (GIS) analysis and logistic regression as a tool to identify and analyse the relative likelihood and its socio-environmental determinants of malaria infection in the Vale do Amanhecer rural settlement, Brazil.

Methods: A GIS database of georeferenced malaria cases, recorded in 2005, and multiple explanatory data layers was built, based on a multispectral Landsat 5 TM image, digital map of the settlement blocks and a SRTM digital elevation model.

Factors associated with the incidence of malaria in settlement areas in the district of Juruena, Mato Grosso state, Brazil.

Factors associated with the incidence of malaria in the Vale do Amanhecer settlement, Juruena, Mato Grosso in 2005 were analyzed. Two hundred settlers of both genders and aged 18 years and above were interviewed. The prevalence of malaria reported in 2005 was 33%.

Spatial patterns of malaria in a land reform colonization project, Juruena municipality, Mato Grosso, Brazil.

Background: In Brazil, 99% of malaria cases are concentrated in the Amazon, and malaria's spatial distribution is commonly associated with socio-environmental conditions on a fine landscape scale. In this study, the spatial patterns of malaria and its determinants in a rural settlement of the Brazilian agricultural reform programme called "Vale do Amanhecer" in the northern Mato Grosso state were analysed.

Methods: In a fine-scaled, exploratory ecological study, geocoded notification forms corresponding to malaria cases from 2005 were compared with spectral indices, such as the Normalized Difference Vegetation Index (NDVI) and the third component of the Tasseled Cap Transformation (TC_3) and thematic layers, derived from the visual interpretation of multispectral TM-Landsat 5 imagery and the application of GIS distance operators.

[Socioenvironmental factors associated with the spatial distribution of malaria in the Vale do Amanhecer settlement, Municipality of Juruena, State of Mato Grosso, 2005].

Malaria is a disease with focal distribution. In Brazil, settlement and gold mining areas in the Legal Amazon region present a great concentration of cases. This paper analyzes the spatial distribution of malaria cases taking into consideration environmental and social factors in the Vale do Amanhecer settlement in the municipality of Juruena, Mato Grosso, Brazil.

[Epidemiologic surveillance in the plan for intensification of malaria control actions in the state of Mato Grosso: a case study].

The objective of this study is to analyze the epidemiologic surveillance in the Malaria Control Actions Intensification Plan (PIACM) in the 18 cities of the state of Mato Grosso, from 1999 to 2002. An evaluative research of the type implantation analysis was conducted. The analysis was carried out using a logic model considering 4 dimensions - external and political context, organizational context, implementation and effectiveness - and 5 evidence bases, 3 of primary data and 2 of secondary data.

Spatial analysis for stratification of priority malaria control areas, Mato Grosso State, Brazil.

The goal of this study was to stratify priority areas for malaria control in the State of Mato Grosso, Brazil, based on spatial analysis. The variables used were: Annual Parasite Index (API), Plasmodium falciparum/Plasmodium vivax ratio, population variation, number of families settled, and percent of deforested area. The Moran's I and Local Moran Test were applied, visualized with the Box Map and Moran Map, for 1986- 1991, 1992-1997, and 1998-2003.

Habitat suitability mapping of Anopheles darlingi in the surroundings of the Manso hydropower plant reservoir, Mato Grosso, Central Brazil.

Background: Hydropower plants provide more than 78 % of Brazil's electricity generation, but the country's reservoirs are potential new habitats for main vectors of malaria. In a case study in the surroundings of the Manso hydropower plant in Mato Grosso state, Central Brazil, habitat suitability of Anopheles darlingi was studied. Habitat profile was characterized by collecting environmental data.

[Epidemiological trends of malaria in the State of Mato Grosso, from 1980 to 2003].

The temporal and spatial evolution of malaria in Mato Grosso was determined in periods from 1980-1985, 1986-1991, 1992-1997 and 1998-2003 and distributed by homogeneous microregion. The annual parasitic index of the state rose until 1992 and then diminished to 1.9 cases/1,000 inhabitants in 2003, the ratio of mortality and the lethality rate were greater in the 1980s.
