The temporal and spatial evolution of malaria was described for the postfrontier phase of the Brazilian Amazon in 2003–2013. The current ecological study aimed to understand the relationship between spatial population mobility and the distribution of malaria cases. The study identified epidemiologically relevant areas using regional statistical modeling and spatial analyses that considered differential infections and types of work activities. Annual parasite incidence (API) in the region was highest in hotspots along the Amazon River and in the south and west settlement zone of Hiléia, with concentrations in environmental protection areas and açaí and Brazil nut extraction areas. The dispersal force decreased in the Central Amazon due to rapid urbanization and improved socioeconomic conditions for workers in consolidated settlement areas. The study characterized the spatial patterns of disease transmission according to the economic activity and regionalization of geographic areas, confirming that the incidence of infection by work activity and labor flow is linked to extractive activities and agricultural settlements.

Introduction:The objective of this study was to understand and assess the perception of communities, organized civil society, health professionals, and decision-makers of several governmental institutions, regarding vulnerabilities and health impacts in drought prone municipalities of Brazil.Methods:This study was carried out through a qualitative investigation in eight municipalities in the Brazilian Semiarid region. Data collection was done through semi-structure and structure interviews, and discussion with local actors, which included communities groups, health professionals, governmental managers and organized civil society.ResultsThe results point to the local actors’ concerns and to the fragility of the health sector in the planning of integrated actions directed towards risks and impacts associated with drought conditions on human health.Discussion:The lack of a specific knowledge contributes to making invisible the process that determines the impacts of drought on health, leading to an acceptance of drought in those municipalities, reducing the capacity of the health system to respond to droughts.Keywords:drought, vulnerability, risks, health, perception, Brazilian Semiarid, resilience

Over the last few decades, the occupation of the Amazon and the expansion of large-scale economic activities have exerted a significant negative impact on the Amazonian environment and on the health of the Amazon’s inhabitants. These processes have altered the context of the manifestation of health problems in time and space and changed the characteristics of the spatial diffusion of health problems in the region. This study analyzed the relationships between the various economic processes of territorial occupation in the Amazon and the spatial diffusion of homicidal violence through the configuration of networks of production, as well as the movements of population and merchandise. Statistical data on violence, deforestation, the production of agricultural items, and socio-economic variables, georeferenced and available for the 771 municipalities of the Legal Amazon were used in this study. The results suggest that the diffusion of violence closely follows the economic expansion front, which is related to deforestation and livestock production but has little relation to grain production, demonstrating steps and typologies of recent occupation in the Amazon that promote violence. These spatial patterns reveal environmental and socio-economic macro-determinants that materialize in geographic space through the construction of highways and the formation of city networks.
