What causes necrotizing fasciitis?
fasciitis is caused by several kinds of bacteria. Some of these bacteria also
cause infections such as
strep throat and
impetigo. Usually the infections caused by these
bacteria are mild. But in rare cases they can cause a more dangerous
You can get necrotizing fasciitis when bacteria enter a wound, such as from an insect bite, a burn, or a cut. You can also get it in:
Wounds that come in contact with ocean water,
raw saltwater fish, or raw oysters, including injuries from
handling sea animals such as crabs.
An intestinal surgery site, or in tumors
or gunshot injuries in the intestines.
A muscle strain or bruise,
even if there is no break in the skin.
The bacteria that cause necrotizing fasciitis can be passed
from person to person through close contact, such as touching
the wound of the infected person. But this rarely happens unless the person who is exposed to the
bacteria has an open
wound, chickenpox, or an
impaired immune system.
What are the symptoms?
The symptoms often start
suddenly after an injury. You may need medical care right away if you have pain that gets better over 24
to 36 hours and then suddenly gets worse. The pain may be much worse than you
would expect from the size of the wound or injury. You may also have:
Skin that is
red, swollen, and hot to the touch.
A fever and
Nausea and vomiting.
The infection may spread rapidly. It quickly can become
life-threatening. You may go into
shock and have damage to skin, fat, and the tissue covering the muscles. (This damage is called gangrene.) Necrotizing fasciitis
can lead to organ failure and death.
How is necrotizing fasciitis diagnosed?
will diagnose your infection based on how suddenly your symptoms started and
how quickly the infection is spreading. The infected tissue may be tested for
bacteria. You also may need
CT scan, or an
MRI to look for injury to your organs or to find out
how much the infection has spread.
