ANTIGENIC AND BIOLOGICAL CLASSIFICATION OF DENGUE VIRUSES.
Abstract
Dengue viruses are the cause of two distinct diseases, dengue fever (DF), a mild and self limited illness and dengue hemorrhagic fever (DHF), a severe disease with an appreciable mortality rate. This investigation addressed itself to the hypothesis that two subpopulations of dengue viruses exist, virulent and avirulent, and that the virulence of a dengue infection is correlated with identifiable antigenic markers on the virus. In addition, an attempt was made to evaluate in sub-human primates the hypothesis that a second dengue infection is modified by host factors to result in more severe disease response. (Author)
