- Candida auris, a deadly drug-resistant fungus spreading rapidly in U.S. hospitals, is becoming an increasing global threat due to its resistance to antifungal drugs and human immune systems, according to a new scientific review.
- The fungus has caused about 7,000 cases in the U.S. in 2025 and has been identified in at least 60 countries, with outbreaks forcing some hospital ICUs to shut down.

- Researchers stress the urgent need for novel antifungal agents, improved diagnostics, immune- and
