Many cellulitis and soft-tissue infections can be treated on an outpatient basis with oral antibiotics and do not result in lasting sequelae. Most patients’ conditions respond well to oral antibiotics. When outpatient therapy is unsuccessful, or for patients who require admission initially, IV antibiotics are usually effective.

Cellulitis may progress to serious illness by uncontrolled contiguous spread, including via the lymphatic or circulatory systems. Associated conditions or complications include lymphangitis, abscess formation, and, rarely, gangrenous cellulitis or necrotizing fasciitis. [53] Certain species, most notably group A beta-hemolytic Streptococcus (GABHS) and S aureus, produce toxins that may mediate a more severe systemic infection, leading to septic shock and death.
