How is necrotizing fasciitis passed from person to person?

Necrotizing fasciitis is not directly contagious and is not passed from person to person in the traditional sense. It is typically caused by bacteria, such as Group A Streptococcus, that can enter the body through breaks in the skin, such as cuts, surgical wounds, or insect bites. While the bacteria can be present on the skin or in the throat of healthy individuals, the infection usually arises from the individual's own flora or environmental sources, rather than through direct transmission from another person. Maintaining good hygiene and treating wounds promptly can help reduce the risk of infection.
