A geographical sampling method for surveys of mosquito larvae in an urban area using high-resolution satellite imagery
Troyo Rodríguez, Adriana; Fuller, Douglas O.; Calderón Arguedas, Ólger; Beier, John C. (2008-06-01)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. ... -
A geographical sampling strategy for field surveys in an urban area using high-resolution satellite imagery
Troyo Rodríguez, Adriana; Fuller, Douglas O.; Calderón Arguedas, Ólger; Beier, John C. (2006-11)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 ... -
Associations between urban structure and Aedes aegypti larval habitats in Puntarenas, Costa Rica
Troyo Rodríguez, Adriana; Arheart, Kristopher L.; Fuller, Douglas O.; Calderón Arguedas, Ólger; Beier, John C. (2008-12)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 ... -
Comparison of mosquito control programs in seven urban sites in Africa, the Middle East, and the Americas
Impoinvil, Daniel E.; Ahmad, Sajjad; Troyo Rodríguez, Adriana; Keating, Joseph; Githeko, Andrew K.; Mbogo, Charles M.; Kibe, Lydiah; Githure, John I.; Gad, Adel M.; Hassan, Ali N.; Orshan, Laor; Warburg, Alon; Calderón Arguedas, Ólger; Sánchez Loría, Victoria M.; Velit Suárez, Rosanna; Chadee, Dave D.; Novak, Robert J.; Beier, John C. (2007-10)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, ... -
Dengue in Costa Rica: the gap in local scientific research
Troyo Rodríguez, Adriana; Porcelain, Sherri L.; Calderón Arguedas, Ólger; Chadee, Dave D.; Beier, John C. (2006)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 ... -
Dengue vector (Aedes aegypti) larval habitats in an urban environment of Costa Rica analysed with ASTER and QuickBird imagery
Fuller, Douglas O.; Troyo Rodríguez, Adriana; Calderón Arguedas, Ólger; Beier, John C. (2010-01-13)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) ... -
Evaluation of predictive maps for Aedes aegypti larval habitats in two urban areas of Costa Rica
Troyo Rodríguez, Adriana; Calderón Arguedas, Ólger; Avendaño López, Adrián; Mora Pineda, Geovanny; Beier, John C.; Fuller, Douglas O. (2011-12)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
Troyo Rodríguez, Adriana; Fuller, Douglas O.; Beier, John C. (2009-11)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 ... -
El Niño Southern Oscillation and vegetation dynamics as predictors of dengue fever cases in Costa Rica
Fuller, Douglas O.; Troyo Rodríguez, Adriana; Beier, John C. (2009-03-04)Dengue fever (DF) and dengue hemorrhagic fever (DHF) are growing health concerns throughout Latin America and the Caribbean. This study focuses on Costa Rica, which experienced over 100 000 cases of DF/DHF from 2003 to ... -
Participatory risk mapping of malaria vector exposure in northern South America using environmental and population data
Fuller, Douglas O.; Troyo Rodríguez, Adriana; Alimi, Taiwo; Beier, John C. (2014-03-01)Malaria elimination remains a major public health challenge in many tropical regions, including large areas of northern South America. In this study, we present a new high spatial resolution (90 × 90 m) risk map for Colombia ... -
Seasonal profiles of Aedes aegypti (Diptera: Culicidae) larval habitats in an urban area of Costa Rica with a history of mosquito control
Troyo Rodríguez, Adriana; Calderón Arguedas, Ólger; Fuller, Douglas O.; Solano Chinchilla, Mayra Emilia; Avendaño López, Adrián; Arheart, Kristopher L.; Chadee, Dave D.; Beier, John C. (2008-06-01)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 ... -
The effects of human movement on the persistence of vector-borne diseases
Cosner, Chris; Beier, John C.; Cantrell, Robert Stephen; Impoinvil, Daniel E.; Kapitanski, Lev; Potts, Matthew David; Troyo Rodríguez, Adriana; Ruan, Shigui (2009-06)With the recent resurgence of vector-borne diseases due to urbanization and development there is an urgent need to understand the dynamics of vector-borne diseases in rapidly changing urban environments. For example, many ... -
Urban structure and dengue incidence in Puntarenas, Costa Rica
Troyo Rodríguez, Adriana; Fuller, Douglas O.; Calderón Arguedas, Ólger; Solano Chinchilla, Mayra Emilia; Beier, John C. (2009-07-15)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 ...
