Candida Auris Cases Surge Across 27 U.S. States as Drug-Resistant Fungus Raises Health Concerns

More than 3,400 clinical cases of drug-resistant Candida auris have been reported across 27 U.S. states in 2026, according to provisional CDC data. California leads the country with 873 cases.

Thousands of Candida Auris Cases Reported Across the United States

A potentially deadly and drug-resistant fungal infection is continuing to raise concerns across the United States, with thousands of clinical cases of Candida auris (C. auris) reported in 27 states so far in 2026.

According to provisional data from the U.S. Centers for Disease Control and Prevention (CDC), 3,437 clinical cases of Candida auris had been documented nationwide as of the week ending July 25, 2026.

The figures highlight the continuing challenge posed by C. auris, a type of yeast that can cause severe infections, particularly among people receiving care in hospitals, nursing homes and other healthcare facilities.

California recorded the highest number of cases, with 873 infections, accounting for roughly one-quarter of the national total. Texas followed with 433 cases, while Tennessee and Ohio recorded 283 and 279 cases respectively.

The spread has also been reported in several other states, demonstrating that Candida auris remains a significant infection-control concern across multiple regions of the country.

States Reporting the Highest Number of Cases

The provisional CDC figures show significant differences in the number of reported clinical cases among states.

The states with the highest reported totals include:

- California — 873 cases

- Texas — 433 cases

- Tennessee — 283 cases

- Ohio — 279 cases

- Georgia — 193 cases

- Louisiana — 179 cases

- Illinois — 171 cases

- Arizona — 171 cases

- Michigan — 146 cases

- Virginia — 132 cases

- Pennsylvania — 121 cases

The remaining states reporting cases each recorded fewer than 100 clinical cases during the period covered by the provisional data.

The concentration of cases in California is particularly notable, with the state's reported total significantly exceeding that of other states.

However, health officials warn that the presence of Candida auris should not be viewed simply as a measure of community transmission because the fungus is strongly associated with healthcare environments and vulnerable patients.

What Is Candida Auris?

Candida auris is a type of yeast that can cause serious infections in humans.

Unlike many common fungal infections, C. auris has attracted international attention because some strains are resistant to one or more antifungal medications.

This resistance can make infections more difficult to treat and increases the importance of early detection and infection-control measures.

Candida auris can cause infections when it enters the body, particularly in people whose immune systems are weakened or who have serious underlying medical conditions.

People in healthcare settings can face greater exposure because the fungus can remain on surfaces and equipment for extended periods.

How Does Candida Auris Spread?

One of the characteristics that makes C. auris particularly challenging for healthcare facilities is its ability to survive on surfaces for prolonged periods.

The fungus can spread through contact with contaminated objects and surfaces, including equipment and frequently touched areas within healthcare facilities.

Potentially contaminated surfaces may include:

- Bedrails

- Doorknobs

- Medical equipment

- Patient-care equipment

- Other frequently touched surfaces

The CDC has described C. auris as highly transmissible between patients through contact with contaminated surfaces or objects.

The fungus can also spread through people who carry it without developing symptoms.

This condition is known as colonization.

What Does Colonization Mean?

Colonization occurs when Candida auris is present on or in a person's body without causing signs or symptoms of an active infection.

A person who is colonized may not feel sick, but the fungus can still potentially spread to other people or surfaces.

This makes infection-control measures especially important in hospitals, nursing homes and other healthcare environments.

Healthcare workers may use screening and other infection-prevention procedures to identify people who may be carrying the fungus.

Who Is Most at Risk?

Candida auris does not affect everyone in the same way.

The greatest concern is generally among people who are already seriously ill or who have other factors that make them more vulnerable to infection.

People at increased risk may include patients who:

- Spend extended periods in healthcare facilities

- Have weakened immune systems

- Have invasive medical devices

- Have undergone major medical procedures

- Have prolonged hospital stays

- Have previously received certain antimicrobial treatments

Patients in intensive-care and long-term healthcare environments may be particularly vulnerable because of their exposure to multiple healthcare procedures and equipment.

For most healthy people, the risk of developing a serious C. auris infection is considerably lower than it is for vulnerable healthcare patients.

Why Is Candida Auris Considered Dangerous?

The main concern surrounding Candida auris is not simply that it is a fungus. The bigger challenge is its combination of serious infections, transmission in healthcare environments and resistance to antifungal drugs.

Some C. auris infections can be resistant to several antifungal medicines.

When an infection does not respond to standard treatments, doctors may have fewer therapeutic options available.

The fungus can also be difficult to identify using some traditional laboratory methods. Accurate identification is important because treatment and infection-control decisions can depend on knowing which organism is responsible for an infection.

What Symptoms Can Candida Auris Cause?

Symptoms can vary depending on where the infection occurs.

Candida auris can cause bloodstream infections and infections involving other parts of the body.

Possible signs of serious infection may include:

- Fever

- Chills

- Fatigue

- Low blood pressure

- Symptoms associated with bloodstream infection

- Other signs of serious illness

However, symptoms are not specific to Candida auris and can resemble those caused by other infections.

That means people cannot reliably determine whether they have C. auris based on symptoms alone.

Laboratory testing is required to identify the fungus.

Anyone who is seriously ill or develops concerning symptoms should seek appropriate medical care, particularly if they have recently been hospitalized or have other risk factors for serious infection.

Why Healthcare Facilities Are a Major Concern

Candida auris presents a particular challenge in healthcare settings because the fungus can persist on surfaces and spread between patients.

Hospitals, nursing homes and long-term care facilities frequently care for people who may already have weakened immune systems or require invasive medical equipment.

Shared environments can also create opportunities for microorganisms to spread if appropriate infection-prevention measures are not followed.

Healthcare facilities therefore play an important role in detecting, isolating and controlling C. auris.

Measures such as proper cleaning and disinfection, hand hygiene, appropriate protective equipment and infection-control procedures can help reduce transmission.

California Has the Highest Number of Reported Cases

California stands out in the latest provisional figures.

The state reported 873 clinical cases, making up approximately one-quarter of the 3,437 cases reported nationwide during the period.

Texas was second with 433 cases, while Tennessee and Ohio each recorded more than 275 cases.

The distribution demonstrates that Candida auris is not limited to a single part of the United States.

Cases have been identified across multiple regions, underscoring the importance of nationwide surveillance and infection-control efforts.

Should the Public Be Worried?

The reported numbers are significant, but they do not mean that everyone in the United States faces the same level of risk.

Candida auris is primarily an issue of concern for people who are medically vulnerable and those receiving care in healthcare environments.

For the general public, awareness is more useful than panic.

People who are hospitalized or living in long-term care facilities can ask their healthcare providers about infection-prevention measures, particularly if they have risk factors that could make them more susceptible to serious infections.

Healthcare workers and facilities also have an important role in limiting transmission by following recommended infection-control practices.

Why Surveillance Matters

Monitoring Candida auris cases helps health authorities understand where the fungus is spreading and which populations may be at greatest risk.

Surveillance can also help healthcare facilities respond more quickly when cases are identified.

Because C. auris can be difficult to identify and may be resistant to antifungal medications, early detection can be particularly important.

The latest figures are described as provisional, meaning they may change as additional information is reported, reviewed and finalized.

Consequently, the reported 3,437 cases should be understood as a snapshot of the available data rather than necessarily representing the final number of cases for the year.

What Can Be Done to Reduce the Spread?

Preventing the spread of Candida auris requires coordinated action, particularly in healthcare environments.

Important infection-control measures include:

1. Proper Hand Hygiene

Regular and thorough hand hygiene is one of the most important ways to reduce the spread of infectious organisms.

2. Cleaning and Disinfection

Healthcare facilities must appropriately clean and disinfect surfaces and equipment that may become contaminated.

3. Early Detection

Rapid identification of C. auris can help healthcare providers implement appropriate precautions.

4. Infection-Control Precautions

Healthcare workers may use specific precautions when caring for patients who are infected or colonized.

5. Appropriate Medical Treatment

Doctors may need laboratory information to determine the most appropriate antifungal treatment, particularly when drug resistance is suspected.

Candida Auris in 2026: What the Numbers Tell Us

The provisional 2026 figures provide another indication that Candida auris remains an important public-health and healthcare concern in the United States.

With 3,437 clinical cases reported across 27 states through the week ending July 25, the fungus continues to affect healthcare systems in multiple parts of the country.

California's 873 cases represent the largest reported total, followed by Texas with 433.

The figures also reinforce why health authorities continue to emphasize surveillance, laboratory identification and infection prevention.

While C. auris can cause severe illness, the greatest risks are concentrated among people who are already medically vulnerable, particularly those receiving prolonged healthcare.

For the wider public, understanding how the fungus spreads and why healthcare facilities take special precautions can help reduce unnecessary fear while promoting awareness.
