Definition

Flesh-eating bacterial syndrome, also known as necrotizing fasciitis, is a severe infection that rapidly destroys muscles, fat, and skin tissue. It is typically caused by bacteria such as Group A Streptococcus.

5 Must Know Facts For Your Next Test

  1. Necrotizing fasciitis often starts from minor cuts or abrasions but can quickly progress to severe tissue damage.
  2. Common symptoms include intense pain, fever, swelling, and redness at the infection site; advanced stages may show skin discoloration and blistering.
  3. Diagnosis relies on clinical evaluation, imaging techniques like MRI or CT scans, and lab tests to identify the causative bacteria.
  4. Treatment usually involves surgical removal of dead tissue (debridement), intravenous antibiotics, and sometimes hyperbaric oxygen therapy.
  5. Delayed treatment can lead to severe complications such as sepsis, organ failure, or death.
