Journal ArticleDOI
Origins of dengue type 2 viruses associated with increased pathogenicity in the Americas.
Rebeca Rico-Hesse,Lisa M. Harrison,Rosa Alba Salas,Duilia Tovar,Ananda Nisalak,Celso Ramos,Jorge Boshell,Maria Teresa R. de Mesa,Rita Maria Ribeiro Nogueira,Amelia P.A. Travassos Da Rosa +9 more
TL;DR: Phylogenetic analyses suggest that these genotypes of dengue type 2 virus originated in Southeast Asia and that they displaced the native, American genotype in at least four countries, and vaccination and other control efforts should therefore be directed at decreasing the transmission of these "virulent" genotypes.
Journal ArticleDOI
Diversity and evolution of the envelope gene of dengue virus type 1.
Ana P. Goncalvez,Ananias A. Escalante,Flor H. Pujol,Juan E. Ludert,Duilia Tovar,Rosa Alba Salas,Ferdinando Liprandi +6 more
TL;DR: Very low average value of the ratio of nonsynonymous-to-synonymous nucleotide substitutions, relative to the respective sites, indicated that the evolution of the E gene of the DV-1 is subject mostly to purifying selection.
Journal ArticleDOI
Isolation, characterization and geographic distribution of Caño Delgadito virus, a newly discovered South American hantavirus (family Bunyaviridae)
Charles F. Fulhorst,Martha C. Monroe,Rosa Alba Salas,Gloria Duno,Antonio Utrera,Thomas G. Ksiazek,Stuart T. Nichol,Nuris de Manzione,Duilia Tovar,Robert B. Tesh +9 more
TL;DR: The results of serological tests and analyses of small and medium RNA segment nucleotide sequence data indicated that VHV-574 represents a novel hantavirus (proposed name 'Caño Delgadito') that is distinct from all previously characterized hantviruses.
Journal ArticleDOI
Emergence of a new epidemic/epizootic Venezuelan equine encephalitis virus in South America
TL;DR: Phylogenetic analysis of strains isolated during two outbreaks indicated that the new epidemic/epizootic virus(es) evolved recently from an enzootic VEE virus in northern South America.
Journal ArticleDOI
Venezuelan Hemorrhagic Fever: Clinical and Epidemiological Studies of 165 Cases
Nuris de Manzione,Rosa Alba Salas,Hector Paredes,Oswaldo Godoy,Luis Rojas,Francisco Araoz,Charles F. Fulhorst,Thomas G. Ksiazek,James N. Mills,Barbara A. Ellis,Clarence J. Peters,Robert B. Tesh +11 more
TL;DR: Principal symptoms among the patients with VHF included fever, malaise, headache, arthralgia, sore throat, vomiting, abdominal pain, diarrhea, convulsions, and a variety of hemorrhagic manifestations.
