Imported dengue--United States, 1992.

Dengue is a mosquito-transmitted acute disease caused by any of four virus serotypes (DEN-1, DEN-2, DEN-3, and DEN-4) and characterized by the sudden onset of fever, headache, myalgia, rash, nausea, and vomiting. The disease is endemic in most tropical areas of the world and can occur in U.S. residents returning from international travel. Serum samples from 68 persons with suspected imported dengue with onset in 1992 (1) were submitted to CDC from 23 states (Table 1). Of these, 17 (25%) cases (from 10 states) were serologically or virologically diagnosed as dengue. This report summarizes information about these 17 cases.
