In 2023 alone, U.S. health officials recorded 4,514 clinical cases of candida auris, a drug-resistant fungus that has been rising steadily in healthcare settings since it was first detected in the country in 2016. This sharp increase is a major warning sign for hospitals and long-term care facilities, because candida auris spreads easily between very sick patients, survives on surfaces and equipment, and often does not respond to common antifungal medications. As a result, candida auris has become a serious patient safety threat, forcing infection-prevention teams to rethink how they screen, isolate, and protect high-risk patients.
Candida auris is a type of yeast (fungus) that can cause serious infections in people who are already very sick. It has been identified in growing numbers since the first U.S. case was reported in 2016, with thousands of clinical cases now recorded across the country. Many more people are “colonized,” meaning it lives on their skin or other body sites without causing symptoms.
Unlike many other Candida species, experts do not think candida auris naturally lives on healthy people. Most patients pick it up in healthcare settings from contaminated surfaces, equipment, or close contact with someone who already has the fungus.
Candida auris can cause:
In the sickest patients, candida auris infections can lead to sepsis, shock, and organ failure.
These are patients:
These patients often depend on invasive medical devices that keep them alive but also give candida auris a direct path into the body.
Major risk factors for candida auris include:
These devices bypass the usual skin barriers and make it easier for candida auris on the skin or environment to reach the bloodstream, lungs, or urinary tract.
One of the biggest problems for healthcare facilities is that many people have candida auris on their skin or body sites without any symptoms at all. This is called colonization.
Colonized patients:
Because there are no obvious signs, colonized patients can be moved between units and even between facilities while still shedding candida auris into their surroundings.
This silent spread makes early screening and strong infection-control policies critical.
Candida auris is frequently resistant to one or more major classes of antifungal drugs. That means:
Echinocandins are usually the first-line treatment and can cure many candida auris infections. But when the strain is multidrug-resistant, clinicians may have to use combinations of drugs or newer agents with limited evidence. This raises the risk of treatment failure and poor outcomes.
Candida auris is built for survival in healthcare environments. It can:
Not all common disinfectants kill it. If a facility uses the wrong products or does not apply them correctly, the fungus can remain on surfaces even after cleaning. This keeps feeding the cycle of contamination and spread.
Candida auris can be difficult for standard lab systems to identify correctly. It may be mistaken for other yeast species without the right technology and methods. That leads to:
To manage candida auris properly, healthcare facilities need access to reliable lab testing and must know when to suspect the fungus-especially when a patient looks septic but does not respond to antibiotics.
Many patients who get sick from candida auris are already at high risk of dying because of their underlying illnesses. Studies suggest candida auris infection may be linked to mortality rates as high as 30% to 60% in some groups.
It is often impossible to say how much of a patient’s death was due to candida auris versus their other conditions. But for healthcare facilities, every added infection means:
It mainly spreads through contact, not through the air.
Key routes of spread include:
Because patients can stay colonized for weeks, months, or longer, candida auris can keep circulating inside a facility if infection-control basics are not followed strictly.
Outbreaks also spread between facilities when colonized or infected patients are transferred. If the receiving facility is not told about the patient’s candida auris history, they may not put proper precautions in place, giving the fungus a head start in a new environment.
Facilities need firm, consistent IPC practices for both infected and colonized patients:
These basics sound simple, but they must be applied consistently on every shift to keep candida auris from spreading.
Screening is key to finding colonized patients who have no symptoms. Healthcare facilities can:
A positive screening test means the patient is colonized. Most colonized patients do not need antifungal treatment, but they do need infection-control measures (isolation, proper cleaning, PPE use) to protect others.
Overuse and misuse of antibiotics and antifungals contribute to resistance. To help control candida auris, facilities should:
This protects patients’ natural defenses and slows the emergence of more drug-resistant strains of candida auris.
Whenever a patient with known or suspected candida auris moves between facilities, there must be clear handoff communication. The receiving facility should know if the patient:
This lets the new facility put the right precautions in place from day one.
Patients, families, and visitors also have a role in reducing the spread.
Simple steps include:
Healthy family members are unlikely to get sick from candida auris, but they can still help break the chain of transmission by sticking to good hand hygiene and safe care practices.
It hangs around on bedrails, touchscreens, carts, and shared medical equipment long after a patient leaves the room. If your team is relying only on manual wipe-downs and basic cleaners, you are asking staff to fight a multidrug-resistant fungus with tools that were never designed for it.
Instead of depending on who cleaned the room, how rushed they were, or what they might have missed, an advanced room decontamination system from AeroClave gives you a consistent, repeatable whole-room treatment. The goal is simple: reach high-touch and hard-to-reach surfaces the same way every time when candida auris is a concern.
This kind of repeatable process:
A defined decontamination protocol also lets you standardize disinfection across different spaces, including:
Environmental services, infection control, and nursing can all share one documented workflow for when to run a cycle, how long it takes, and when the room can safely be turned over after potential candida auris exposure. That makes it easier to train new staff, enforce policies, and show surveyors and public health partners that your facility is taking candida auris seriously.
If your facility is seeing candida auris cases, has high-risk units, or is worried about silent colonization, now is the time to tighten your environmental disinfection plan-not after an outbreak hits the news.
To get started:
Then, fill out the form below to request a readiness review with AeroClave. A member of the team will walk through your current processes, discuss gaps and priorities, and show how a tailored whole-room decontamination solution can fit your beds, your units, and your budget so you can better protect your patients and staff.

Candida auris is a serious threat because it targets the sickest patients, spreads silently through colonization, survives for long periods on surfaces and equipment, and often resists standard antifungal drugs and common disinfectants. Healthcare facilities must treat candida auris as a high-priority infection-control challenge by tightening hand hygiene, using effective environmental disinfection products, isolating infected or colonized patients appropriately, screening high-risk populations, and improving communication during patient transfers. By taking these steps now, leaders can reduce outbreaks, protect vulnerable patients, and ease the burden on staff and resources. Use the contact form below to connect with a decontamination expert and learn how advanced room disinfection technology can strengthen your candida auris control strategy and help safeguard your facility.
Candida auris is a yeast (fungus) that causes serious infections in people who are usually already very sick and in healthcare facilities. It can infect the blood, wounds, ears, and urinary tract, and it often resists common antifungal drugs.
It is a problem because it targets very sick, high-risk patients, spreads easily in hospitals and long-term care settings, survives on surfaces and equipment for a long time, and is often resistant to multiple antifungal medicines. These factors make it hard to treat and hard to control once it gets into a facility.
It spreads mainly through contact, not through the air. It moves from person to person via hands, shared medical equipment, and contaminated surfaces like bedrails and doorknobs. Colonized patients who have no symptoms can still shed the fungus and spread it to others.
Most healthy people without underlying medical problems do not get sick from it. They are not the main group at risk. The biggest risk is for people who are hospitalized, in nursing homes or long-term acute care facilities, have weakened immune systems, or use invasive devices like central lines and ventilators.
Current evidence does not support airborne spread. Candida auris is usually carried on the skin and spread by contact with contaminated surfaces, equipment, or hands. Contact precautions and environmental cleaning are the main control strategies.
Most infections are treated with echinocandin antifungal medications. If the strain is resistant, clinicians may use combinations of drugs or newer treatments. Because many patients are already very sick, close monitoring and strong supportive care are also important.
It is hard to know the exact mortality rate because most patients with candida auris have serious medical conditions that already carry a high risk of death. Some studies suggest that mortality among infected patients may be in the 30% to 60% range.
Facilities can reduce risk by applying strict hand hygiene, using disinfectants proven to kill candida auris, screening at-risk patients for colonization, using gloves, gowns, and appropriate isolation, communicating status during patient transfers, and practicing strong antimicrobial stewardship.
AeroClave provides advanced decontamination systems designed to help healthcare and public safety facilities standardize and strengthen their environmental disinfection processes, supporting infection-control teams as they work to limit the spread of tough pathogens like candida auris.
