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 ...
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 ...
Urban structure and dengue incidence in Puntarenas, Costa Rica
Dengue is currently the most important arboviral disease globally and is usually associated with built environments in tropical areas. Remotely sensed information can facilitate the study of urban mosquito-borne diseases ...
Comparison of mosquito control programs in seven urban sites in Africa, the Middle East, and the Americas
Mosquito control programs at seven urban sites in Kenya, Egypt, Israel, Costa Rica, and Trinidad are described and compared. Site-specific urban and disease characteristics, organizational diagrams, and strengths, weaknesses, ...
Seasonal profiles of Aedes aegypti (Diptera: Culicidae) larval habitats in an urban area of Costa Rica with a history of mosquito control
Dengue is the most important arboviral disease worldwide and the principal vector-borne disease in Costa Rica. Control of Aedes aegypti populations through source reduction is still considered the most effective way of ...
A geographical sampling method for surveys of mosquito larvae in an urban area using high-resolution satellite imagery
Entomological surveys in urban areas are often biased by selecting houses or locations with known high vector densities. A sampling strategy was developed for Puntarenas, Costa Rica, using high-resolution satellite imagery. ...
Dengue vector (Aedes aegypti) larval habitats in an urban environment of Costa Rica analysed with ASTER and QuickBird imagery
Dengue fever is transmitted mainly by the mosquito species Aedes aegypti , which breeds in water-filled containers in tropical urban areas. In this study medium- and high-resolution satellite (ASTER and QuickBird) ...
Dengue in Costa Rica: the gap in local scientific research
Dengue en Costa Rica: la brecha en la investigación científica local
Globalization has affected the reemergence of infectious diseases, with increased human travel and trade facilitating the introduction of diseases into new areas and the resurgence of diseases that had been eliminated in ...
