| spatial point analysis based on dengue surveys at household level in central brazil. | dengue virus (denv) affects nonimunne human populations in tropical and subtropical regions. in the americas, dengue has drastically increased in the last two decades and brazil is considered one of the most affected countries. the high frequency of asymptomatic infection makes difficult to estimate prevalence of infection using registered cases and to locate high risk intra-urban area at population level. the goal of this spatial point analysis was to identify potential high-risk intra-urban ar ... | 2008 | 18937868 |
| evaluation of a commercial real-time pcr kit for detection of dengue virus in samples collected during an outbreak in goiania, central brazil, in 2005. | in the past 2 decades, dengue has reemerged in brazil as a significant public health problem. clinicians demand a diagnostic test with high sensitivity that is applicable during the early symptomatic phase. we aimed to test two distinct molecular methods on samples from suspected dengue cases during an outbreak in central brazil. acute-phase serum specimens from 254 patients suspected of having dengue were collected during 2005 in the city of goiânia, central brazil. samples were blindly evaluat ... | 2007 | 17409201 |

| [first autochthonous cases, caused by the dengue-3 serotype in federal district, brazil]. | during the first four months of 2003, the survey laboratory of the federal district (lacen laboratory of virology), brasília, brazil, isolated ten strains of dengue virus serotype 3, five of them autochthonous, and the remaining ones from cases imported from tocantins, goias and bahia states. the virus isolations were performed in c6/36 cell culture inoculated with total blood collected between the 1st and the 5th days after the onset of the symptoms. the age of the patients varied from 26 to 59 ... | 2006 | 16821435 |
| household survey of dengue infection in central brazil: spatial point pattern analysis and risk factors assessment. | urban dengue fever is now considered a major public health threat in most american countries. a household survey was conducted in the city of goiania in central brazil in 2001 to assess prevalence of dengue infection and individual and area-based risk factors. spatial point pattern analysis was performed using the dual kernel method. a total of 1,610 households were surveyed; 1,585 individuals more than five years old had blood and data collected. sera were tested for igm/igg antibodies by an en ... | 2004 | 15569799 |
