Necrotizing fasciitis is a serious infection of the skin, the tissue just beneath the skin (subcutaneous tissue), and the tissue that covers internal organs (fascia). Necrotizing fasciitis can be caused by several different types of bacteria, and the infection can arise suddenly and spread quickly. Early signs include flu-like symptoms and redness and pain around the infection site. A prompt diagnosis and treatment are essential. If the infection is not treated promptly, it can lead to multiple organ failure and death. Treatment typically includes intravenous (IV) antibiotics and surgery to remove infected and dead tissue.
