Quick answer: Drug-resistant fungal infections are rising in the U.S., led by a yeast called Candida auris. The CDC counted 6,304 clinical cases in 2024. Cases still go up every year, though the increase has slowed since 2022. The people at real risk are already very sick, mostly in hospitals and nursing homes. Healthy people, including visitors, rarely get sick from it.

Drug-Resistant Fungal Infections are becoming one of the fastest-growing public health concerns in the United States. While bacterial infections often receive the most attention, health experts are increasingly warning that certain fungi are evolving resistance to the medications used to treat them. As these infections become more difficult to control, hospitals, healthcare providers, and researchers are working together to improve prevention, diagnosis, and treatment.
Although the situation is serious, medical professionals emphasize that increased awareness, better infection-control practices, and ongoing scientific research are providing hope for reducing the impact of these dangerous infections.
What Are Drug-Resistant Fungal Infections?
Drug-Resistant Fungal Infections occur when fungi develop the ability to survive medications that once killed them. This means standard antifungal drugs may no longer work effectively, making infections harder to treat and increasing the risk of severe illness.
One of the best-known examples is Candida auris, an emerging fungus that has caused outbreaks in healthcare facilities across the United States. Because it can spread easily in hospitals and nursing homes, health officials closely monitor new cases.
Unlike common fungal infections such as athlete’s foot or mild yeast infections, drug-resistant fungal diseases often affect people with weakened immune systems, including cancer patients, transplant recipients, older adults, and people receiving intensive medical care.
Why Cases Are Increasing
Several factors are contributing to the rise of Drug-Resistant Fungal Infections in the United States.
First, advances in modern medicine allow more people with serious illnesses to survive longer. While this is positive, it also means more individuals have weakened immune systems that make them vulnerable to fungal infections.
Second, the widespread use of antifungal medications can encourage fungi to develop resistance over time, similar to how bacteria become resistant to antibiotics.
Climate change may also play a role. Scientists believe warmer global temperatures could allow certain fungi to adapt and survive in environments that were previously unsuitable, potentially increasing their spread.
Improved testing and surveillance are another reason more infections are being detected today. Hospitals now have better tools to identify dangerous fungal species that may have gone unnoticed in the past.
Who Faces the Greatest Risk?
Although anyone can develop a fungal infection, Drug-Resistant Fungal Infections pose the greatest danger to:
- Hospital patients receiving long-term care
- People with weakened immune systems
- Organ transplant recipients
- Cancer patients undergoing chemotherapy
- Individuals with diabetes or chronic illnesses
- Residents of nursing homes and rehabilitation centers
Healthy individuals generally face a much lower risk of developing severe fungal disease.
Symptoms Can Be Difficult to Recognize
One challenge with Drug-Resistant Fungal Infections is that symptoms often resemble those of bacterial or viral illnesses.
Common symptoms may include:
- Persistent fever
- Chills
- Fatigue
- Bloodstream infections
- Wounds that fail to heal
- Organ complications in severe cases
Because symptoms can be nonspecific, early laboratory testing is often essential for identifying the correct cause.
Hospitals Are Strengthening Prevention
Healthcare facilities across the country are taking stronger measures to reduce the spread of Drug-Resistant Fungal Infections.
These efforts include:
- Enhanced patient screening
- Strict hand hygiene protocols
- Improved environmental cleaning
- Isolation procedures for infected patients
- Better monitoring of antifungal medication use
Many hospitals have also expanded infection-control training for healthcare workers to help prevent outbreaks before they begin.
Scientists Continue to Search for Better Treatments
Researchers are actively developing new medications to combat Drug-Resistant Fungal Infections. Pharmaceutical companies and universities are studying innovative antifungal drugs that target fungi in new ways, reducing the likelihood of resistance.
Scientists are also exploring faster diagnostic tests that can identify resistant fungi within hours rather than days. Earlier diagnosis allows doctors to begin the most effective treatment sooner, improving patient outcomes.
Artificial intelligence and genomic sequencing are becoming valuable tools for tracking fungal mutations and predicting future outbreaks.
How the Public Can Help Reduce Risk
While most people do not need to worry about severe fungal infections, everyone can take simple steps to lower their risk.
Helpful preventive measures include:
- Practice good hand hygiene.
- Follow wound-care instructions carefully.
- Complete prescribed medications as directed.
- Avoid using antifungal medicines unnecessarily.
- Seek medical care if persistent fever or unusual symptoms develop after hospitalization.
Public awareness plays an important role in limiting the spread of Drug-Resistant Fungal Infections.
Looking Ahead
Although Drug-Resistant Fungal Infections represent a growing healthcare challenge, experts remain optimistic that improved surveillance, medical innovation, and stronger infection-prevention strategies will slow their spread.
Continued investment in research, public education, and hospital safety programs will be critical in protecting vulnerable patients. As healthcare systems adapt to this emerging threat, early detection and responsible medication use will remain the strongest defenses.
Conclusion
The rise of Drug-Resistant Fungal Infections in the United States highlights the importance of staying ahead of evolving health threats. While these infections can be serious, advances in medical research, improved hospital practices, and greater public awareness are creating new opportunities to reduce their impact. By supporting early diagnosis, responsible treatment, and ongoing scientific innovation, the nation can respond effectively to this growing challenge.
What to do if a family member is in the hospital or a nursing home
You can’t control a hospital’s cleaning crew. But you can lower the odds that germs spread to the person you love.
- Clean your hands every time. Use soap or hand sanitizer when you enter and leave the room.
- Follow the sign on the door. If staff ask you to wear a gown and gloves, wear them, even for a short visit.
- Don’t sit on the bed or set bags on it. C. auris can live on surfaces for a long time.
- Ask about devices. It’s fair to ask, “Does this catheter or line still need to be in?” Every day a device stays in adds risk.
- Speak up about fever. Tell the nurse if a patient develops a new fever or chills that don’t improve on antibiotics.
- Share past results. If your relative ever tested positive or was screened, tell every new hospital or nursing home.
What a “positive screening” means
Some hospitals swab a patient’s skin to check for C. auris. A positive swab often means the person is colonized, not sick.
Colonized means the yeast lives on the skin without causing an infection. The person may feel fine. But the CDC says they can still spread it to others, so staff use extra precautions.
A positive screen is not a reason to panic. It is a reason to tell future care providers, so they can protect you and other patients.
A made-up example: These are made-up examples to explain how it works. Linda, 78, spends three weeks in a long-term care unit after a stroke. Before she moves to a rehab center, a skin swab comes back positive for C. auris. She has no fever and no infection. The rehab center gives her a private room and staff wear gowns. Her daughter writes “C. auris colonized, Oct. 2026” on Linda’s medication list, so any future ER visit starts with the right precautions.
Common mistakes families make
- Assuming it’s “just a yeast infection.” C. auris is not the same as the common yeast infections treated at home.
- Using leftover antifungal cream or pills. Taking antifungal medicine you don’t need can help resistance grow.
- Skipping the gown because “I’m family.” Visitors can carry the yeast to other rooms on their clothes and hands.
- Not asking questions. Hospitals expect families to ask about infection control. You won’t offend anyone.
Does insurance cover treatment?
Treatment for a fungal infection in the hospital is part of the hospital stay. Medicare Part A and most private plans cover inpatient care, subject to your deductible and coinsurance.
Long stays can get expensive. If a bill looks wrong or too high, ask for an itemized bill. Many charges can be reduced.

FAQ
Can a healthy person catch Candida auris?
It’s possible but uncommon. The CDC says healthy people, including health workers and visitors, generally do not carry it or get sick from it.
How many C. auris cases are there in the U.S.?
The CDC reported 6,304 clinical cases in 2024. Cases have risen every year since the first U.S. case in 2016, though more slowly since 2022.
Is Candida auris curable?
Many infections respond to echinocandin antifungals. Infections that resist several drug classes are harder to treat, and doctors may combine medicines.
What are the symptoms?
There are no unique symptoms. Fever and chills that don’t improve with antibiotics are common, which is why lab testing matters.
Should I avoid visiting a relative who has it?
No. Visit, but follow the hospital’s precautions: clean your hands and wear a gown and gloves if asked.
Bottom line
Drug-resistant fungi are a real and growing problem, but mostly for patients who are already very sick. Clean hands, fewer unneeded devices and telling providers about past test results are the best protection. If someone you love is in the hospital, you are part of the safety team.
