Abstract

PIP: Dengue viral infection produces a spectrum of disease. For example, mild dengue disease is characterized by biphasic fever, myalgia, arthralgia, leukopenia, and lymphadenopathy, while dengue hemorrhagic fever is an often fatal disease characterized by hemorrhages and shock syndrome. The disease, especially in its severe form, is seen more often among children than among adults. With focus upon India, dengue's etiology, epidemiology, pathology, pathogenesis of dengue hemorrhagic fever, clinical manifestations of both the mild and severe forms of dengue viral infection, diagnosis, differential diagnosis, treatment, prevention, and prognosis are discussed.
