Seasonal profiles of Aedes aegypti (Diptera: Culicidae) larval habitats in an urban area of Costa Rica with a history of mosquito control
(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 ...
Dengue vector (Aedes aegypti) larval habitats in an urban environment of Costa Rica analysed with ASTER and QuickBird imagery
(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) ...
The effects of human movement on the persistence of vector-borne diseases
(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 ...
Comparison of mosquito control programs in seven urban sites in Africa, the Middle East, and the Americas
(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, ...
Participatory risk mapping of malaria vector exposure in northern South America using environmental and population data
(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 ...
Associations between urban structure and Aedes aegypti larval habitats in Puntarenas, Costa Rica
(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 ...
A geographical sampling method for surveys of mosquito larvae in an urban area using high-resolution satellite imagery
(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
(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 ...
Urban structure and dengue incidence in Puntarenas, Costa Rica
(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 ...
El Niño Southern Oscillation and vegetation dynamics as predictors of dengue fever cases in Costa Rica
(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 ...
