Fever in patients with HIV infection.

Fever is a common sign during the course of HIV infection, usually represents a superimposed opportunistic infection, and is almost always a treatable condition. Proper management generally requires detection of the underlying cause, and the diagnostic evaluation is largely driven by the clinical symptoms, associated conditions such as injection drug use, and stage of disease based largely on the absolute CD4 cell count. This article provides guidelines for the management of fever in the patient with HIV infection.
