Mucormycosis is a life-threatening fungal infection.


A group of fungi cause mucormycosis. They're in soil, decaying plants or wood, and compost piles. The fungi enter the body through cuts in the skin or by inhaling it into the sinuses and lungs. Once in the body, the fungi can spread fast.

In healthy people, the body removes the fungi before problems start.
