The Candida auris outbreak in US is spreading rapidly, with thousands of cases reported across the country. According to recent reports by the CDC, more than 3,100 clinical cases across 27 states have been detected, while screening cases who carry the fungus without necessarily having symptoms puts the total to 6,669. Moreover, Candida auris cases in US remain concentrated in several states. Texas reported 715 cases, followed by Michigan with 518 and Illinois with more than 350.
The drug-resistant fungus is most dangerous for people who are already seriously ill, have weakened immune systems, or depend on medical devices. Experts stress that the risk to healthy people in the wider community remains low.
Candida Auris Cases in US Continue to Raise Concern
Texas currently stands out in the Candida auris outbreak in US. Candida auris in Texas had 1,148 combined clinical and screening cases, while California recorded the highest number of clinical cases at 873.
Candida auris in Michigan has also emerged as a major concern, with 503 cases reported through July, leading to 518 cases in August.
Candida auris in Illinois also ranks among the states with substantial reported deadly fungal infections, with more than 350 cases in July.
The Candida auris outbreak in US in the past had similar numbers, with reported cases rising from 2,882 in 2022 to 4,428 in 2023 and 6,197 in 2024.
What Is Candida Auris Infection: The Deadly Fungus Superbug?
The Candida auris (C. auris ) infection is caused by a type of yeast that can enter the bloodstream and spread through the body. Unlike many common fungal infections, the Candida Auris strain is a drug-resistant fungus, making treatment more difficult.
The Candida Auris fungus can also remain on surfaces and medical equipment for long periods. It may spread through contaminated objects, healthcare equipment, or direct contact, allowing it to move between vulnerable patients.
Nathan Wiederhold, PharmD, director of the Fungus Testing Laboratory at The University of Texas at San Antonio, said the organism is particularly concerning because many strains resist azole antifungals, while some also resist amphotericin B, a drug sometimes used when other treatments fail.
Who Is Most at Risk of Superbug Infection Outbreak in US?
These deadly fungi, Candida auris, are primarily affecting medically vulnerable people rather than healthy members of the general public.
Those at greatest risk of Candida auris outbreak in US include:
- Patients with weakened immune systems
- People with serious underlying illnesses
- Long-term hospital patients
- Residents of nursing and long-term care facilities
- Patients using ventilators, feeding tubes, or urinary and central venous catheters
Some people can carry C. auris on their skin without developing symptoms. This silent colonization can make infection-control efforts more challenging.
Candida Auris Symptoms and Treatment
Symptoms of Candida auris infection can vary depending on where the infection occurs. They may include fever, chills, fatigue, low blood pressure, and a rapid heart rate. Because these signs can resemble other illnesses, laboratory testing is needed for confirmation.
Echinocandins, a class of antifungal medicines, are generally used as the main treatment. However, drug-resistant infections may require multiple or alternative antifungal therapies under specialist care.
Unlike some recent outbreaks in USA, such as the Salmonella outbreak and measles outbreak, C. auris is primarily a healthcare-associated threat. The Candida auris outbreak in US is a challenge for healthcare systems as it requires controlling infections that can persist in medical environments.
How Can the Candida Auris Outbreak in US Be Prevented?
Healthcare facilities can reduce transmission through:
- Hand hygiene
- Gloves and gowns for patient care
- Private rooms or appropriate isolation precautions
- Dedicated medical equipment
- Effective environmental disinfectants
- Screening high-risk patients
- Rapid laboratory identification and communication during patient transfers
For the public, experts recommend basic hygiene, particularly when visiting healthcare facilities or helping someone with medical devices.
