Deadly Fungus Spreads Across US: Nearly Half of States Affected
3 Aug
Summary
- Candida auris, a drug-resistant fungus, is spreading rapidly in 2026.
- Nearly half of US states have reported cases, with Texas and Michigan leading.
- The fungus can be deadly in healthcare settings for vulnerable patients.

The drug-resistant fungus Candida auris continues its rapid spread across the United States in 2026, according to recent data. Nearly half of all U.S. states have reported cases to the Centers for Disease Control and Prevention.
Texas has emerged as the state with the most reported cases, exceeding 700 as of mid-July. Michigan follows closely with 503 known cases of Candida auris infections. This fungus, often labeled an urgent threat by the CDC, is particularly concerning due to its resistance to standard antifungal medications.
Data from 2022 to 2024 indicates that approximately 88% of clinical cases occurred in individuals over the age of 45, with a majority being men. The fungus thrives in healthcare environments, spreading through contaminated surfaces and medical equipment like catheters and IVs, posing a deadly risk to compromised patients.
