What things affect the chances of getting necrotizing fasciitis?

It is very serious: Many different types of bacteria can cause this infection. The bacteria inter the body, usually through a minor cut or scrape which was not care properly, the bacteria begins to grow and release harmful substances (toxins) that kill tissue and affect blood flow to the area. As the tissue dies, the bacteria enters the blood and rapidly spreads throughout the body.

IV drug abuse: Unfortunately, most cases I have seen come from individuals using dirty needles or unsterile technique when utilizing illegal IV drugs. So don't start a drug habit! your overall health will also contribute - diabetes, immunocompromised, etc.

Nonsterile technique: generally it is a infection that occurs from the use of contaminated needles. diabetics can get a similar infection in the scrotal area. this is a life threatening infection requiring emergent surgical debridement.
