Includes:
Prevention of trauma or breaking of skin integrity (that may constitute portals of entry for the infection)
Treatment of cellulitis to prevent extension into subcutaneous tissue[5]
Immunization against varicella zoster virus (in adults and children), that may prevent necrotizing fasciitis as a complication of skin breaks due to chickenpox or zoster[34]
Infection control practices should be in place in the hospital to prevent patient to patient spread of group A streptococcus in all patients, including those with type II necrotizing fasciitis.
Chemoprophylaxis may be considered for close contacts of patients with invasive group A streptococcus disease including necrotizing fasciitis, especially if those contacts are at high-risk for invasive group A streptococcus disease, though it is not routinely recommended.[62]
