Spatial analysis of Aedes aegypti immatures in Northern Argentina: Clusters and temporal instability
The objective of this study was to analyze the spatio-temporal patterns of Aedes aegypti immatures based on four entomological surveys that inspected over 6000 households in a large neighborhood of the city of Clorinda between 2007 and 2008. Global and local spatial point pattern analyses of immatur...
