A drug-resistant fungus known as Candida auris poses an ‘urgent antimicrobial resistance threat,’ according to health officials from the Centers for Disease Control and Prevention (CDC). This year, nearly two dozen states in the U.S. have detected this fungus, making it a widespread concern. The CDC’s latest data, ending July 25, 2026, indicates that screenings have occurred in multiple states. Twenty-three states have reported at least one screening case, and the fungus has spread across all major U.S. regions.
High Case Numbers Across States
Texas reports the highest number of cases, with 715, followed by Michigan with 518, and Illinois with 379. Other states with significant case numbers include Ohio, Nevada, New Jersey, Arizona, Maryland, and Virginia, with triple-digit figures. Some states like Arkansas and Montana have reported screenings but no cumulative cases. CDC’s surveillance figures may change as health departments update reports.
The Nature of Candida Auris
Candida auris is a type of yeast, a fungus that can cause serious illness in some cases. Drug resistance in some strains makes treatment difficult. Often, the fungus spreads in hospitals or long-term care facilities. Those with healthy immune systems might not get sick but can still transmit it to others. The fungus first appeared in the U.S. in 2016 and has since grown rapidly.
Spread and Detection
A CDC review found that nearly 90% of clinical infections between 2022 and 2024 occurred in individuals aged 45 years and older. Most affected individuals were in acute healthcare settings.
For effective prevention, health officials stress the importance of rapid detection and screening programs. Infection-control measures in healthcare settings are crucial to stop the fungus from spreading.
Identifying Symptoms
The symptoms of a Candida auris infection vary depending on the infection site. According to the Cleveland Clinic, symptoms may include:
- Chills
- Extreme tiredness
- Fever
- Low blood pressure
- Low body temperature
- High heart rate
- Pain, pressure, or a full feeling inside the ear
Many experiencing an infection might already be seriously ill, disguising symptoms, and asymptomatic individuals can still transmit the fungus to others. Candida auris spreads through person-to-person contact and contaminated surfaces. In healthcare settings, infections can move through contaminated medical equipment like catheters, IVs, and breathing tubes.
