Pyrexia of Unknown Origin (PUO) represents a prolonged fever, typically lasting over 3 weeks, with no apparent cause despite extensive medical testing. PUO is categorized into four types: classic, where the cause is unknown even after hospitalization; nosocomial, where the fever arises during a hospital stay; neutropenic, affecting patients with a weakened immune system; and HIV-related, associated with individuals infected with HIV.
