Feb. 25: Improving Malaria Understanding and Control with the Aid of Spatial Analytical Approaches

This is a reminder that t he Morrison Institute Winter Colloquium on Population Studies ( http://www.stanford.edu/group/morrinst/c.html ) continues on Wednesday, February 25 , 2009, when Marcia Castro of the Harvard University School of Public Health presents “Improving Malaria Understanding and Control with the Aid of Spatial Analytical Approaches.” Diverse types of malaria contexts can be observed based on local characteristics. Frontier malaria, such as observed in the Brazilian Amazon, is a biological, ecological, and sociodemographic phenomenon operating over time at three spatial scales (micro-individual, community, and state and national). Urban malaria, such as observed in many African cities, is characterized by focal transmission also determined by a myriad of factors. In both cases, improved understanding of the most important determinants of malaria risk and transmission requires spatially explicit analysis. The presentation will show applications for each type. First, an approach that combined spatial analysis, geostatistical tools, and fuzzy sets models revealed that the early stages of frontier settlement are dominated by environmental risks, consequential to ecosystem transformations that promote larval habitats of Anopheles darlingi. With the advance of forest clearance and the establishment of agriculture, ranching, and urban development, malaria transmission is substantially reduced, and risks of new infection are largely driven by human behavioral factors. Second, a methodological approach using spatial analysis and remote sensing applied to multiple data sources (entomological, household, and parasitological data) provides inputs for community based integrated vector control approaches in urban settings. 

Marcia Castro is Assistant Professor Of Demography in the Department of Global Health and Population at Harvard’s School of Public Health. She earned her PhD in Demography at Princeton, and has written extensively on malaria, mosquito control, and spatial demography. 

The Morrison Institute for Population and Resource Studies Winter Colloquium is a lecture series for students, the Stanford community, and the general public that presents the latest scientific findings in demography, epidemiology, genetics, and other areas in the field of population and resource studies. 

The Winter Colloquium is held on Wednesdays of the Winter Quarter, 4:15 p.m. in Herrin Hall T-175 (Biological Sciences building).
