A previously reported case of childhood dengue shock syndrome in an American traveler to India was investigated serologically. The original studies neither indicated the infecting serotype nor proved primary or secondary infection. However, BHK suspension PRNT of 6-year convalescent serum now indicates that the child had primary dengue type 3 infection. Dengue, dengue hemorrhagic fever, and dengue shock syndrome are potential hazards for American travelers and American residents of dengue-receptive areas.
