About The Disease
"Flesh-eating bacteria” is a misnomer as the bacteria do not actually eat the tissue. They cause the destruction of skin and muscle by releasing toxins (virulence factors), which include streptococcal pyogenic exotoxins.
Necrotizing Fasciitis infection begins locally, at a site of trauma, which may be severe (such as the result of surgery), minor, or even non-apparent.
Patients usually complain of intense pain that may seem in excess given the external appearance of the skin. With progression of the disease, tissue becomes swollen, often within hours.
Diarrhea and vomiting are also common symptoms. In the early stages, signs of inflammation may not be apparent if the bacteria are deep within the tissue.
The first sign of infection may be a small, reddish, painful spot or bump on the skin. This quickly changes to a very painful bronze- or purple-colored patch that grows rapidly.
Skin color may progress to violet and blisters may form, with subsequent necrosis (death) of the subcutaneous tissues. The center may become black and die off. The skin may break open and ooze fluid. The wound may quickly grow in less than an hour.
Patients with necrotizing fasciitis typically have a fever and appear very ill. Mortality rates have been noted as high as 73 percent if left untreated. Without surgery and medical assistance, such as antibiotics, the infection will rapidly progress, and will eventually lead to death.
Had Mr Evans been treated immediately by a competent medical professional, he would have likely survived. Patients are typically taken to surgery based on a high index of suspicion, determined by the patient's signs and symptoms.
According the U.S. Government U.S. National Institutes Of Health, in necrotizing fasciitis, powerful, broad-spectrum antibiotics must be given immediately through a vein (IV). Surgery is required to open and drain infected areas and remove dead tissue. Sometimes donor immunoglobulins (antibodies) are given by vein to help fight the infection.
Noteworthy Flesh-Eating Disease Survivors
Lucien Bouchard, former premier of Québec, Canada, who became infected in with necrotizing fasciitis 1994 while leader of the federal official opposition Bloc Québécois party. He lost a leg to the illness and survived due to proper medical care.
Eric Allin Cornell, winner of the 2001 Nobel Prize in Physics, lost his left arm and shoulder to the disease in 2004.
Jan Peter Balkenende, Prime Minister of the Netherlands since 2002, was infected in 2004. He was in the hospital for several weeks, but recovered fully.
Alan Coren, British writer and satirist, announced in his Christmas 2006 column for The Times that his long absence as a columnist had been due to contracting the disease while on holiday in France.
Prevention
According to the U.S. National Institutes Of Health, an agency of the US Department of Health and Human Services, thoroughly cleaning any site of broken skin during an injury to the skin is the only known prevention.
