A deadly superbug is spreading across the U.S., challenging healthcare and public safety.
Story Highlights
- Drug-resistant fungus Candida auris infected over 7,000 people in 2025.
- The fungus poses a significant threat in healthcare settings.
- Experts warn about fungi adapting to human body temperatures.
- Severe cases often require intensive care and mechanical ventilation.
Candida Auris: A Growing Threat
The Centers for Disease Control and Prevention (CDC) reports that Candida auris, a drug-resistant fungus, has infected at least 7,000 individuals in 2025.
This superbug, first discovered in the U.S. in 2016, thrives in healthcare settings and has become a serious problem for hospitals and nursing homes. Its ability to survive on surfaces and spread through medical equipment makes it particularly dangerous to vulnerable patients.

This fungus’s resistance to traditional treatments leaves infected individuals with limited options. As Melissa Nolan, an assistant professor of epidemiology and biostatistics at the University of South Carolina, explains, “If you get infected with this pathogen that’s resistant to any treatment, there’s no treatment we can give you to help combat it. You’re all on your own.”
Impact on Healthcare Facilities
More than half of U.S. states reported clinical cases of Candida auris in 2025. The annual case count is nearing last year’s record-breaking figure of over 7,500 cases.
This presents a significant challenge for healthcare facilities already struggling with resource constraints. The CDC’s estimates indicate that 30–60% of infected individuals succumb to the infection, often due to underlying health conditions.
A study in July 2025 revealed alarming statistics: over half of the infected patients required intensive care, a third needed mechanical ventilation, and many required blood transfusions. The average age of these patients was 60-64, highlighting the risk in older populations.
Adapting to a Changing Climate
Microbiologist Arturo Casadevall at Johns Hopkins University suggests that climate change could exacerbate the threat posed by Candida auris.
Warmer global temperatures could enable fungi to overcome the human body’s natural defenses, allowing them to thrive within us. This potential adaptation underscores the need for continued vigilance and research to combat such emerging threats.
