The treatment, maintenance, and suppression of infection in chronic wounds remain a challenge to all practitioners. From an infectious disease standpoint, knowing when a chronic wound has progressed from colonized to infected, when to use systemic antimicrobial therapy and when and how to culture such wounds can be daunting.

This article will discuss the pathophysiology of infection in older adults, including specific infections such as cutaneous candidiasis, necrotizing soft tissue infection, osteomyelitis, and infections involving hardware.
