A geographical sampling strategy for field surveys in an urban area using high-resolution satellite imagery
Field evaluations for studying the epidemiology of vector-borne diseases like dengue in urban areas are often restricted to selection of households and buildings for field surveys. Therefore, the resulting sampling frame ...
Evaluation of predictive maps for Aedes aegypti larval habitats in two urban areas of Costa Rica
The abundance of Aedes aegypti can be associated with urban structure and tree cover, which conceals and protects containers. The purpose of this study was to create and evaluate predictive maps for Ae. Aegypti larval ...
Modeling dengue cases in health Regions of Costa Rica using El Niño Southern Oscillation and local vegetation dynamics
Temporal behavior of dengue fever and dengue hemorrhagic fever (DH/DHF) has been associated with climate, which may modulate mosquito vector populations. El Niño Southern Oscillation (ENSO) fluctuations can be related to ...
Associations between urban structure and Aedes aegypti larval habitats in Puntarenas, Costa Rica
Geospatial technologies have been increasingly applied to study vector-borne diseases, although their use in urban setting has been limited. In this study, high-resolution satellite imagery from QuickBird was analyzed to ...
Mapping the risk of Aedes aegypti larval habitats using tree cover in Puntarenas, Costa Rica
Tree cover and other characteristics of urban structure have been associated in urban environments with abundance and productivity of Aedes aegypti and other mosquito larval habitats. Tree cover can conceal containers, ...
