چکیده
1. Spatial scaling of frontier malaria – Over the past 35 years, the state of Rondônia in Brazil has been the site of a vast diversity of settlement projects and new communities, developed under both public and private sponsorship. Although the concept of frontier malaria was formulated with a temporal pattern that was specific to a single community, we find that the same temporal pattern extends to a still coarser scale; namely, the entire state of Rondônia with its heterogeneous set of new and expanding communities. We show this evolutionary pattern in section 1.

Deforestation and Malaria on the Amazon Frontier: Larval Clustering of Anopheles darlingi (Diptera: Culicidae) Determines Focal Distribution of Malaria.
We performed bimonthly mosquito larval collections during 1 year, in an agricultural settlement in the Brazilian Amazon, as well as an analysis of malaria incidence in neighboring houses. Water collections located at forest fringes were more commonly positive for Anopheles darlingi larvae and Kulldorff spatial analysis pinpointed significant larval clusters at sites directly beneath forest frin...
متن کاملMalaria risk on the Amazon frontier.
Frontier malaria is a biological, ecological, and sociodemographic phenomenon operating over time at three spatial scales (micro/individual, community, and state and national). We explicate these linkages by integrating data from remote sensing surveys, ground-level surveys and ethnographic appraisal, focusing on the Machadinho settlement project in Rondônia, Brazil. Spatially explicit analyses...
متن کاملAn initial examination of the epidemiology of malaria in the state of Roraima, in the Brazilian Amazon basin.
This study firstly describes the epidemiology of malaria in Roraima, Amazon Basin in Brazil, in the years from 1991 to 1993: the predominance of plasmodium species, distribution of the blood slides examined, the malaria risk and seasonality; and secondly investigates whether population growth from 1962 to 1993 was associated with increasing risk of malaria. Frequency of malaria varied significa...
متن کاملInfluence of Deforestation, Logging, and Fire on Malaria in the Brazilian Amazon
Malaria is a significant public health threat in the Brazilian Amazon. Previous research has shown that deforestation creates breeding sites for the main malaria vector in Brazil, Anopheles darlingi, but the influence of selective logging, forest fires, and road construction on malaria risk has not been assessed. To understand these impacts, we constructed a negative binomial model of malaria c...
متن کاملThe Effect of Malaria on Settlement and Land Use: Evidence from the Brazilian Amazon
We estimate the effect of malaria on settlement and land use patterns in the Brazilian Amazon, where potential settlers were randomly assigned to plots in a newly opened settlement area. The random assignment allows us to estimate the risk of malaria on each plot based only on its characteristics. Using survey data, we find that a high malaria risk significantly reduces the probability that a p...
