Clinical Significance
Dengue and dengue hemorrhagic fever result from infection by any of four serotypes of dengue viruses. Transmission occurs through the bite of infected Aedes mosquitos. In most patients, Dengue Virus antibodies are detectable after the sixth day following the onset of symptoms. Strong cross-reactivity is seen with other group B arboviruses (flavivirus), including St. Louis encephalitis, Japanese B encephalitis, Rio Bravo, Powassan, and Yellow Fever viruses.
