Causes ofnecrotising fasciitis

Necrotising fasciitis can be caused by several different types of bacteria.

The bacteria that cause the infection live in the gut, in the throat, or on the skin of some people, where they dont usually cause any serious problems.

However, in rare cases, they can cause necrotising fasciitis if they get into deep tissue either through the bloodstream, or an injury or wound, such as:

  • cuts and scratches
  • insect bites
  • puncture wounds caused by injecting drugs
  • surgical wounds

Necrotising fasciitis typically occurs when bacteria already on the skin or in the body get into deep tissue.The infection can also be spread from person to person, but this is very rare.

Anyone can get necrotising fasciitis including young and otherwise healthy people but it tends to affect older people and those in poor general health.
