A serious health alert has been issued across the United States as a dangerous and highly resistant fungal pathogen, Candida auris, spreads rapidly through healthcare networks. The Centers for Disease Control and Prevention (CDC) has flagged this yeast as a significant threat, causing severe infections that are difficult to treat.
What is Candida Auris and Why is it Dangerous?
Candida auris is an invasive type of yeast that poses a lethal risk to individuals with compromised immune systems. First identified in 2009 in a patient's ear canal in Japan, it has since become a global concern. India recognised it as a major public health threat in 2014. The fungus is notorious for its resilience, surviving on surfaces and skin for months, even resisting standard cleaning agents and disinfectants. It spreads easily in environments like hospitals and nursing homes through contaminated equipment and direct contact.
The most alarming aspect is its resistance to treatment. Some strains are considered "superbugs," resistant to all common antifungal antibiotics. "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," warned Melissa Nolan, an assistant professor of epidemiology at the University of South Carolina. CDC data indicates it has already infected at least 7,000 people nationwide.
Which US States Are Affected by the Outbreak?
The CDC has reported a worrying geographic spread, with cases now confirmed in 28 states. Health authorities have noted an "alarming" increase in virulence and transmission rates. The Alabama Department of Public Health emphasised the need for "sustained vigilance" as case counts rise each year.
The states currently affected include:
- Oregon, California, Nevada, Montana, Wyoming, Colorado
- Utah, Arizona, Kansas, Texas, Iowa, Louisiana
- Wisconsin, Illinois, Michigan, Indiana, Ohio, Kentucky
- Tennessee, Mississippi, Pennsylvania, West Virginia
- Maryland, Delaware, Virginia, Georgia, North Carolina, Alabama
Symptoms and Severe Health Impacts
The symptoms of a Candida auris infection vary based on the part of the body affected. According to the Cleveland Clinic, they can include:
- Fever and chills
- Lethargy or extreme tiredness
- Low blood pressure and rapid heart rate (tachycardia)
- Low body temperature (hypothermia)
- Ear pain, pressure, or a feeling of fullness
A study from July 2025, published by Cambridge University Press, examined patients in Nevada and Florida. It revealed the infection's severe toll: more than half of the patients required intensive care unit admission, and over one-third needed mechanical ventilation. Patients with an average age between 60 and 64 often required blood transfusions.
Medical experts urge the public to be vigilant. If these symptoms persist, especially after a hospital stay or in a healthcare setting, seeking immediate medical attention is crucial.
