In some cases, it is unknown how the infection began. Once it takes hold, the infection rapidly destroys muscle, skin, and fat tissue.
Causes of Necrotizing Fasciitis
Necrotizing fasciitis is commonly caused by group A Streptococcus (GAS) bacteria. That's the same type of bacteria that causes strep throat. However, several types of bacteria, such as staphylococcus and others, have also been associated with the disease.
Necrotizing fasciitis occurs when such bacteria infect the superficial fascia, a layer of connective tissue below the skin.
Symptoms of Necrotizing Fasciitis
The symptoms of necrotizing fasciitis usually occur within the first 24 hours of infection. They often include a combination of the following:
Increasing pain in the general area of a minor cut, abrasion, or other skin opening.
Pain that is worse than would be expected from the appearance of the cut or abrasion.
Redness and warmth around the wound, though symptoms can begin at other areas of the body.
