Spatio-Temporal Analysis Of The Relationship Between Wnv Dissemination And Environmental Variables In Indianapolis, Usa., Hua Liu, Qihao Weng, David Gaines

Political Science & Geography Faculty Publications

Background: This study developed a multi-temporal analysis on the relationship between West Nile Virus (WNV) dissemination and environmental variables by using an integrated approach of remote sensing, GIS, and statistical techniques. WNV mosquito cases in seven months (April-October) of the six years (2002–2007) were collected in Indianapolis, USA. Epidemic curves were plotted to identify the temporal outbreaks of WNV. Spatial-temporal analysis and k-mean cluster analysis were further applied to determine the high-risk areas. Finally, the relationship between environmental variables and WNV outbreaks were examined by using Discriminant Analysis.

Results: The results show that the WNV epidemic curve reached its peak …

A Study Of The Distribution And Abundance Of The Adult Malaria Vector In Western Kenya Highlands, Li Li, Ling Bian, Guiyun Yan

Political Science & Geography Faculty Publications

Background: A sharp rise in the malaria mortality rate has been observed recently in western Kenya. Malaria is transmitted by mosquito vectors. Malaria control strategies can be more successful if the distribution and abundance of mosquito vectors is predicted. However, how mosquito vectors are distributed in space remain poor understood, and this question is rarely studied using spatial methods. This study aims to provide a better understanding of the distribution and abundance of mosquito vectors. To achieve this objective, spatial and non-spatial methods were employed. The data on the distribution of adult mosquitoes, and mosquito breeding habitats in a study …
