Essential Clinical Features
Two distinct clinical entities are associated with dengue virus infections of man. These are (A) “classical” or primary dengue fever, (B) dengue hemorrhagic fever (DHF) (with or without shock) or secondary dengue. Usage of the terms “primary” and “secondary” denotes that the clinical outcome of an infection may be critically influenced by the patient’s previous experience with dengue virus. A large body of epidemiological evidence, reinforced by laboratory data, does indeed suggest that DHF and the dengue shock syndrome (DSS) are characteristic complications of secondary exposure under specialized conditions affecting mainly children in heavily endemic regions.
