Known as flesh-eating disease, necrotizing fasciitis destroys the body's soft tissues rapidly and can be fatal.
Causes
Usually caused by group A Streptococcus, the condition can also be caused by Staphylococcus aureus or Clostridium perfringens.
Symptoms
The infection may start with a red or swollen area of skin that spreads rapidly, followed by severe pain and fever. Blisters, black spots, and flaky skin may develop as the infection progresses.
Diagnosis
In addition to a physical examination, blood tests, imaging tests, and tissue biopsy may be used to support a diagnosis.
Treatment
In severe cases, amputation may be required to stop infection from spreading. Treatment involves antibiotics and surgery to remove infected tissue.
Prevention
Good wound care, handwashing, and avoiding contact with others' wounds or bandages are all preventive measures.
