Is Necrotizing fasciitis Contagious?
Transmission of Necrotizing fasciitis from Person to Person
Necrotizing fasciitis is considered an infectious disease that is contagious between people under rare circumstances.
Generally, the disease can be transmitted under rare circumstances such as immunocompromised people,
or during surgery with contaminated surgical tools, or according to "rare circumstances" as noted from reputable internet sources.
Necrotizing fasciitis, although infectious, is not a genetic disease. It is not caused by a defective or abnormal gene.
About contagion and contagiousness:
Contagion and contagiousness refers to how easily
the spread of Necrotizing fasciitis is possible from one person to another.
Other words for contagion include "infection", "infectiousness",

Contagiousness has nothing to do with genetics
or inheriting diseases from parents.
