Harrowing headlines in the international media of the so-called flesh-eating bacteria strike fear in millions, especially when it attacks healthy, vibrant people like Aimee Copeland, who lost both hands, her left leg and right foot after she contracted the disease from a fall from a zip line. But despite the public's fascination with this horrific infection, most people do not know the facts. Known in the medical community as necrotizing fasciitis or NF, the flesh-eating bacteria is often caused by the same bacterium that causes strep throat. Once set loose in the body, NF rapidly destroys tissue - sometimes at the rate of an inch per hour. NF is the perfect storm of medical emergencies - surreptitious symptoms that mask themselves like a wolf in sheep's clothing, with excruciating pain as the toxic bacteria tear lightning fast through the subcutaneous tissues, destroying everything in its wake. Amputation of limbs or death is common - sometimes overnight. And no one is safe. Everyone is at risk from newborns to the elderly. What's more, NF is being caused increasingly by bacteria abundant in warm ocean waters, a microscopic monster called Vibrio Vulnificus, as well as by MRSA, an antibiotic-resistant threat that kills nearly 20,000 every year in the U.S. alone, and which has world leaders extremely alarmed.
