title: Primary HIV infection diagnosed in South Africa masquerading as another tropical disease.
abstract: Eleven patients referred to a hospital in South Africa with suspected tropical diseases such as malaria, typhoid fever and South African tick bite fever were found to be suffering from primary human immunodeficiency virus (HIV) infection. Hospital records were reviewed retrospectively in those acutely ill, febrile patients where a clinical suspicion of HIV seroconversion existed and no other diagnosis could be found. A history of recent travel, particularly to malarious areas, was given by most of these patients. The clinical presentation was dominated by high fevers and headaches. The most helpful pointers to primary HIV infection included a characteristic palatal enanthem, leucopenia and thrombocytopenia. Ironically, the history of recent travel appeared to have confounded the diagnosis despite the fact that travel has often been associated with the acquisition of HIV in Africa. Recognition of primary HIV infection masquerading as a tropical disease may result in more frequent diagnosis of this serious condition.
