There’s a new fungus amongus, and it’s raising red flags among health care experts because it resists all the major antifungal treatments.

The discovery involves Candidozyma auris (formerly known as Candida auris), an emerging fungal pathogen that has already become a serious problem in hospitals around the world.

Since it was first described in 2009, this fungus has spread to more than 60 countries across six continents, causing healthcare-associated outbreaks and invasive infections, with mortality rates of 30–50 percent reported in some situations.
