dengue fever is a mosquito-borne disease which is not known to be endemic in iran. in october 2015, a 32-year-old iranian woman was admitted with acute unexplained high-grade fever, headache, pain, rash, diarrhea, leukopenia and elevated liver enzymes after returning from india. serological and molecular analysis for dengue virus (denv) infection revealed positive igm, negative igg and positive...
no. EU056810) and 1986 (accession nos. HM234642 and GU131843) epidemics in Burkina Faso. Strains of DENV-2 from the 2005 epidemic in Ghana (accession no. EU005258) shared 95% identity with that of the patient reported here. Phylogenetic analysis indicated that the dengue virus genome sequence in this case is highly homologous with recent strains in Africa, especially from the 2016, 1986, and 19...
The severe complications of dengue virus infections, hemorrhagic manifestation and shock, are much more commonly observed during secondary infections caused by a different serotype of dengue virus than that which caused the primary infections. It has been speculated, therefore, that dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS) are caused by serotype crossreactive immunopatholo...
BACKGROUND Dengue virus causes one of the most significant infectious diseases in tropical and subtropical regions, notable number of which is imported into China every year. RESULTS In this study, the molecular epidemiologic and phylogenetic analyses of dengue cases imported into Guangzhou in South China during 2009-2013 were conducted. During that period, 46 imported dengue cases were ident...
background and objectives: a single reactive igg anti-dengue virus elisa test in the absence of igm antibodies or ns1 antigen may denote current infection or past exposure to the virus. to determine whether igg index value can be used to identify true current dengue infection we conducted a prospective observational study. materials and methods: suspected dengue patients (n =1745) were tested i...
Dengue fever is the most prevalent arboviral disease in the tropical and sub-tropical regions of the world. The present report describes molecular detection and serotyping of dengue viruses in acute phase blood samples collected from New Delhi, India. Phylogenetic and molecular clock analysis of dengue virus serotype 1 and 3 strains were also investigated. Dengue virus infection was detected in...
This study aims to perform the first molecular and clinical-epidemiological analysis of dengue cases in Divinopolis, MG, Brazil. Data from 4,110 cases of dengue were accessed and 190 clinical samples were collected for molecular analyses. In this study, 2.7% of the men and 3.0% of the women were admitted to hospital. There was no association between gender and hospital admission. The symptoms o...
The aim of this study was to retrospectively determine the prevalence of dengue virus from April 2010 to November 2010 in Brunei Darussalam. A total of 250 serum samples from dengue diagnosed patients were examined. All serum samples were tested for dengue IgM and IgG antibodies and dengue NS1 antigen using the PanBio dengue ELISA commercial kit. To determine the prevalence of dengue virus sero...
BACKGROUND Asymptomatic dengue virus-infected individuals are thought to play a major role in dengue virus transmission. The efficacy of the recently approved quadrivalent CYD-TDV dengue vaccine against asymptomatic dengue virus infection has not been previously assessed. METHODS We pooled data for 3 736 individuals who received either CYD-TDV or placebo at 0, 6, and 12 months in the immunoge...
A molecular clone of Japanese encephalitis virus (JE virus) was derived from the JE virus Nakayama strain and used to produce infectious JE virus in cell culture. The engineered JE virus resembled the parental JE virus in cell-culture properties and was related closely to other JE virus strains based on nucleotide sequence analysis. The JE virus clone was used as a genetic background for constr...
