The initial infection can be from almost any cause (for example, cuts on the skin, puncture wounds, surgical incisions, or rarely, insect bites [spiders, biting flies]). Early symptoms may resemble those of cellulitis and include the following:
  • Instead of healing, the infected site (see above) can show erythema (redness) and swelling.
  • The site may be very sensitive to pain, and skin pain can occur even past the area of erythema.
  • The presence of pain is far in excess of what would be expected based upon physical findings.
  • Fever and chills
  • Fatigue
Progressive or later symptoms include the following:
  • Progressive skin changes such as skin ulceration and bullae (thin-walled fluid-filled blisters) formation
  • Skin discoloration
  • Necrotic scars (black scabs)
  • Gas formation in the tissues (that can produce a crackling sensation under the skin)
  • Fluid and/or pus draining from the site can occur rapidly as the infection progresses.
  • Some patients can become septic, meaning the infection has spread to the bloodstream and throughout the body.
  • Septic shock (bacteremia, low blood pressure, rapid breathing, mental status altered)

Visible infections (skin, hair follicles, fingernails, visible traumasites) are more likely to be noticed and treated than some deep infections. Patients who have any deep infections (muscle, bone, joint, gastrointestinal) are at somewhat higher risk for the disease because the initial infection and subsequent spread is usually not as noticeable as more visible infections.

The initial choice of antibiotics can be made based upon the types of flesh-eating bacteria suspected of causing the infection, but many doctors believe that multiple antibiotics should be used at the same time to protect the patient from methicillin-resistant staphylococcus aureus(MRSA, or sometimes termed flesh-eating bacteria in the popular press), as well as infections with anaerobic bacteria, and polymicrobial infections. 
Many patients with necrotizing fasciitis are very sick, and most require admission to an intensive-care unit. Sepsis and organ failure (renal, pulmonary, and cardiovascular systems) need to be treated aggressively to increase the patient's chance for recovery. Some patients have such extensive damage to limbs that they require skin grafting, plastic surgery, or even amputation.

Further, anything that can help prevent infections will help prevent necrotizing fasciitis. Practices such as hand washing, checking extremities for cuts or wounds if you have diabetes, avoiding physical contact with people who carry MRSA, and good hygiene practices help prevent initial infections that may lead to flesh-eating disease. Immunosuppressed patients should be very careful not to get infections, and people with liver disease should avoid eating seafood that may be contaminated with Vibrio vulnificus. People with liver disease should not have any infections or cuts in the skin exposed to warm seawater to avoid necrotizing fasciitis caused by Vibrio vulnificus.
Physicians, surgeons, and other caregivers play an important role in prevention. Cases of necrotizing fasciitis may occur when surgical sites become infected. Consequently, physicians need to use sterile techniques when doing surgery and adhere to hospital practices such as glove and gown coverage to help prevent infection spread in hospitalized patients. Careful surgical techniques in sites that can easily become contaminated are required. Some examples of such sites are bowel surgery, episiotomy (surgically enlarging the vaginal outlet), and debridement with closure of traumatic wounds.
