| [stratification of a hyperendemic city in hemorrhagic dengue]. | any effort to control dengue hemorrhagic fever (dhf) faces a number of challenges. among these are the great environmental heterogeneity of homes and neighborhoods in urban centers where the primary dengue vector, aedes aegypti, breeds, as well as shortages of resources and of personnel trained in mosquito control. adequate epidemiological surveillance could serve as a basis to begin to stratify urban communities and identify the areas in them where control efforts should be focused. in this stu ... | 2000 | 11141964 |
| [laboratory diagnosis of dengue virus infections in aragua state, venezuela: october 1997-december 1998]. | the efficacy of a proactive dengue surveillance system to predict epidemics depends on the laboratory diagnostic capacity for an early detection of virus circulation. this study shows the results of the dengue virologic and serologic surveillance accomplished in aragua state (venezuela) from october 1997 to december 1998. five hundred and forty seven sera from suspected dengue patients were tested using the techniques of virus isolation and immunofluorescence serotyping (viis), reverse transcrip ... | 2003 | 12822553 |
| [a game as an educational strategy for the control of aedes aegypti in venezuelan schoolchildren]. | to assess the value of a game known as jugando en salud: dengue [playing for health: dengue] as a teaching/learning tool leading to the incorporation of schoolchildren enrolled in secondary school in the control of aedes aegypti and dengue prevention activities in the municipality of girardot, aragua state, venezuela. | 2003 | 14769156 |
| detection of dengue viruses in field-caught aedes aegypti (diptera: culicidae) in maracay, aragua state, venezuela by type-specific polymerase chain reaction. | virological surveillance of dengue viruses in aedes aegypti populations constitutes a powerful tool for early prediction of dengue outbreaks. we have standardized a protocol for viral rna extraction from individual and pools of mosquitoes that permits a sensitive detection of dengue virus without rna degradation or pcr inhibition when we apply a semi-nested rt-pcr. the limit of detection for each dengue serotype was 0.1 pfu. in a prospective field study conducted from november 2000 to december 2 ... | 2005 | 15639750 |
| population structure of the dengue viruses, aragua, venezuela, 2006-2007. insights into dengue evolution under hyperendemic transmission. | during the past three decades there has been a notable increase in dengue disease severity in venezuela. nevertheless, the population structure of the viruses being transmitted in this country is not well understood. here, we present a molecular epidemiological study on dengue viruses (denv) circulating in aragua state, venezuela during 2006-2007. twenty-one denv full-length genomes representing all of the four serotypes were amplified and sequenced directly from the serum samples. notably, only ... | 2011 | 22197765 |
