During an epidemic of dengue type 2 virus in the rural community of Charters Towers, North Queensland, Australia, in 1993, 210 cases presented to the local hospital with signs and symptoms of classic dengue fever. Two cases were noteworthy because of neurologic complications, which included drowsiness, short term memory loss, agitation, and seizure. The cases are presented in detail because they are the first cases of dengue-associated encephalopathy to be documented in Australia. An increasing number of cases of encephalopathy associated with classic dengue fever is being reported worldwide, but the etiology of this clinical syndrome remains unknown.
