Last May, an elderly man was admitted to the Brooklyn branch of Mount Sinai
Hospital for abdominal surgery. A blood test revealed that he was infected
with a newly discovered germ as deadly as it was mysterious. Doctors
swiftly isolated him in the intensive care unit.

The germ, a fungus called Candida auris, preys on people with weakened
immune systems, and it is quietly spreading across the globe. Over the last
five years, it has hit a neonatal unit in Venezuela, swept through a
hospital <https://onlinelibrary.wiley.com/doi/epdf/10.1111/myc.12781> in
Spain, forced a prestigious British medical center to shut down its
intensive care unit, and taken root in India, Pakistan and South Africa
<https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4073876/>.

Recently C. auris reached New York
<https://wwwnc.cdc.gov/eid/article/24/10/18-0649_article#tnF2>, New Jersey
<https://www.cdc.gov/fungal/candida-auris/tracking-c-auris.html> and
Illinois, leading the federal Centers for Disease Control and Prevention to add
it to a list <https://www.cdc.gov/drugresistance/biggest_threats.html> of
germs deemed “urgent threats.”

The man at Mount Sinai died after 90 days in the hospital, but C. auris did
not. Tests showed it was everywhere in his room, so invasive that the
hospital needed special cleaning equipment and had to rip out some of the
ceiling and floor tiles to eradicate it.

“Everything was positive — the walls, the bed, the doors, the curtains, the
phones, the sink, the whiteboard, the poles, the pump,” said Dr. Scott
Lorin, the hospital’s president. “The mattress, the bed rails, the canister
holes, the window shades, the ceiling, everything in the room was positive.”

C. auris is so tenacious, in part, because it is impervious to major
antifungal medications, makingued.

Resistant germs are often called “superbugs,” but this is simplistic
because they don’t typically kill everyone. Instead, they are most lethal
to people with immature or compromised immune systems, including newborns
and the elderly, smokers, diabetics and people with autoimmune disorders
who take steroids that suppress the body’s defenses.

Scientists say that unless more effective new medicines are develop it a
new example of one of the world’s most intractable health threats: the rise
of drug-resistant infections.

For decades, public health experts have warned that the overuse of
antibiotics was reducing the effectiveness of drugs that have lengthened
life spans by curing bacterial infections once commonly fatal. But lately,
there has been an explosion of resistant fungi as well, adding a new and
frightening dimension to a phenomenon that is undermining a pillar of
modern medicine.

“It’s an enormous problem,” said Matthew Fisher, a professor of fungal
epidemiology at Imperial College London, who was a co-author of a recent
scientific review <http://science.sciencemag.org/content/360/6390/739> on
the rise of resistant fungi. “We depend on being able to treat those
patients with antifungals.”

Simply put, fungi, just like bacteria, are evolving defenses to survive
modern medicines.

Yet even as world health leaders have pleaded for more restraint in
prescribing antimicrobial drugs to combat bacteria and fungi — convening
the United Nations General Assembly in 2016 to manage an emerging crisis —
gluttonous overuse of them in hospitals, clinics and farming has contined
and unnecessary use of antimicrobial drugs is sharply curbed, risk will
spread to healthier populations. A study the British government funded
projects <https://amr-review.org/> that if policies are not put in place to
slow the rise of drug resistance, 10 million people could die worldwide of
all such infections in 2050, eclipsing the eight million expected to die
that year from cancer.

In the United States, two million people contract resistant infections
annually, and 23,000 die from them, according to the official C.D.C.
estimate. That number was based on 2010 figures; more recent estimates from
researchers at Washington University School of Medicine
<https://www.cambridge.org/core/journals/infection-control-and-hospital-epidemiology/article/reestimating-annual-deaths-due-to-multidrugresistant-organism-infections/C9B09A787FCCA1EA992AF45066F3FF7C>
put the death toll at 162,000. Worldwide fatalities from resistant
infections are estimated at 700,000 <https://amr-review.org/>.

Antibiotics and antifungals are both essential to combat infections in
people, but antibiotics are also used widely to prevent disease in farm
animals, and antifungals are also applied to prevent agricultural plants
from rotting. Some scientists cite evidence that rampant use of fungicides
on crops is contributing to the surge in drug-resistant fungi infecting
humans.

Yet as the problem grows, it is little understood by the public — in part
because the very existence of resistant infections is often cloaked in
secrecy.

With bacteria and fungi alike, hospitals and local governments are
reluctant to disclose outbreaks for fear of being seen as infection hubs.
Even the C.D.C., under its agreement with states, is not allowed to make
public the location or name of hospitals involved in outbreaks. State
governments have in many cases declined to publicly share information
beyond acknowledging that they have had cases.

All the while, the germs are easily spread — carried on hands and equipment
inside hospitals; ferried on meat and manure-fertilized vegetables from
farms; transported across borders by travelers and on exports and imports;
and transferred by patients from nursing home to hospital and back.

C. auris, which infected the man at Mount Sinai, is one of dozens
<https://www.cdc.gov/drugresistance/biggest_threats.html> of dangerous
bacteria and fungi that have developed resistance. Yet, like most of them,
it is a threat that is virtually unknown to the public.

Other prominent strains of the fungus Candida — one of the most common
causes of bloodstream infections in hospitals — have not developed
significant resistance to drugs, but more than 90 percent of C. auris
infections are resistant to at least one drug, and 30 percent are resistant
to two or more drugs, the C.D.C. said.

Dr. Lynn Sosa, Connecticut’s deputy state epidemiologist, said she now saw
C. auris as “the top” threat among resistant infections. “It’s pretty much
unbeatable and difficult to identity,” she said.

Nearly half of patients who contract C. auris die within 90 days, according
to the C.D.C. Yet the world’s experts have not nailed down where it came
from in the first place.

“It is a creature from the black lagoon,” said Dr. Tom Chiller, who heads
the fungal branch at the C.D.C., which is spearheading a global detective
effort to find treatments and stop the spread. “It bubbled up and now it is
everywhere.”

*‘No need’ to tell the public*

In late 2015, Dr. Johanna Rhodes, an infectious disease expert at Imperial
College London, got a panicked call from the Royal Brompton Hospital, a
British medical center outside London. C. auris had taken root there months
earlier, and the hospital couldn’t clear it.

“‘We have no idea where it’s coming from. We’ve never heard of it. It’s
just spread like wildfire,’” Dr. Rhodes said she was told. She agreed to
help the hospital identify the fungus’s genetic profile and clean it from
rooms.

Under her direction, hospital workers used a special device to spray
aerosolized hydrogen peroxide around a room used for a patient with C.
auris, the theory being that the vapor would scour each nook and cranny.
They left the device going for a week. Then they put a “settle plate” in
the middle of the room with a gel at the bottom that would serve as a place
for any surviving microbes to grow, Dr. Rhodes said.

Only one organism grew back. C. auris.

It was spreading, but word of it was not. The hospital, a specialty lung
and heart center that draws wealthy patients from the Middle East and
around Europe, alerted the British government and told infected patients,
but made no public announcement.

“There was no need to put out a news release during the outbreak,” said
Oliver Wilkinson, a spokesman for the hospital.

This hushed panic is playing out in hospitals around the world. Individual
institutions and national, state and local governments have been reluctant
to publicize outbreaks of resistant infections, arguing there is no point
in scaring patients — or prospective ones.

Dr. Silke Schelenz, Royal Brompton’s infectious disease specialist, found
the lack of urgency from the government and hospital in the early stages of
the outbreak “very, very frustrating.”

“They obviously didn’t want to lose reputation,” Dr. Schelenz said. “It
hadn’t impacted our surgical outcomes.”

By the end of June 2016, a scientific paper reported “an ongoing outbreak
of 50 C. auris cases”
<https://aricjournal.biomedcentral.com/articles/10.1186/s13756-016-0132-5>
at Royal Brompton, and the hospital took an extraordinary step: It shut
down its I.C.U. for 11 days, moving intensive care patients to another
floor, again with no announcement.

Days later the hospital finally acknowledged to a newspaper that it had a
problem. A headline
<https://www.telegraph.co.uk/news/2016/07/08/intensive-care-unit-closed-as-three-people-die-from-new-superbug/>
in The Daily Telegraph warned, “Intensive Care Unit Closed After Deadly New
Superbug Emerges in the U.K.” (Later research said there were eventually 72
total cases, though some patients were only carriers and were not infected
by the fungus.)

Yet the issue remained little known internationally, while an even bigger
outbreak had begun in Valencia, Spain, at the 992-bed Hospital Universitari
i Politècnic La Fe. There, unbeknown to the public or unaffected patients,
372 people were colonized — meaning they had the germ on their body but
were not sick with it — and 85 developed bloodstream infections. A paper in
the journal Mycoses
<https://onlinelibrary.wiley.com/doi/full/10.1111/myc.12781> reported that
41 percent of the infected patients died within 30 days.

A statement from the hospital said it was not necessarily C. auris that
killed them. “It is very difficult to discern whether patients die from the
pathogen or with it, since they are patients with many underlying diseases
and in very serious general condition,” the statement said.

As with Royal Brompton, the hospital in Spain did not make any public
announcement. It still has not.

One author of the article in Mycoses, a doctor at the hospital, said in an
email that the hospital did not want him to speak to journalists because it
“is concerned about the public image of the hospital.”

The secrecy infuriates patient advocates, who say people have a right to
know if there is an outbreak so they can decide whether to go to a
hospital, particularly when dealing with a nonurgent matter, like elective
surgery.

“Why the heck are we reading about an outbreak almost a year and a half
later — and not have it front-page news the day after it happens?” said Dr.
Kevin Kavanagh, a physician in Kentucky and board chairman of Health Watch
USA <http://www.healthwatchusa.org/HWUSA-Officers/bios/_Kavanagh.htm>, a
nonprofit patient advocacy group. “You wouldn’t tolerate this at a
restaurant with a food poisoning outbreak.”

Health officials say that disclosing outbreaks frightens patients about a
situation they can do nothing about, particularly when the risks are
unclear.

“It’s hard enough with these organisms for health care providers to wrap
their heads around it,” said Dr. Anna Yaffee, a former C.D.C. outbreak
investigator who dealt with resistant infection outbreaks in Kentucky in
which the hospitals were not publicly disclosed. “It’s really impossible to
message to the public.”

Officials in London did alert the C.D.C. to the Royal Brompton outbreak
while it was occurring. And the C.D.C. realized it needed to get the word
to American hospitals. On June 24, 2016, the C.D.C. blasted a nationwide
warning to hospitals and medical groups and set up an email address,
candidaauris at cdc.gov, to field queries. Dr. Snigdha Vallabhaneni, a key
member of the fungal team, expected to get a trickle — “maybe a message
every month.”

Instead, within weeks, her inbox exploded.

*Coming to America*

In the United States, 587 cases of people having contracted C. auris have
been reported, concentrated with 309 in New York, 104 in New Jersey and 144
in Illinois, according to the C.D.C.

The symptoms — fever, aches and fatigue — are seemingly ordinary, but when
a person gets infected, particularly someone already unhealthy, such
commonplace symptoms can be fatal.

The earliest known case in the United States involved a woman who arrived
at a New York hospital on May 6, 2013, seeking care for respiratory
failure. She was 61 and from the United Arab Emirates, and she died a week
later, after testing positive for the fungus. At the time, the hospital
hadn’t thought much of it, but three years later, it sent the case to the
C.D.C. after reading the agency’s June 2016 advisory.

This woman probably was not America’s first C. auris patient. She carried a
strain different from the South Asian one most common here. It killed a
56-year-old American woman who had traveled to India in March 2017 for
elective abdominal surgery, contracted C. auris and was airlifted back to a
hospital in Connecticut that officials will not identify. She was later
transferred to a Texas hospital, where she died.

The germ has spread into long-term care facilities. In Chicago, 50 percent
of the residents at some nursing homes have tested positive for it, the
C.D.C. has reported. The fungus can grow on intravenous lines and
ventilators.

Workers who care for patients infected with C. auris worry for their own
safety. Dr. Matthew McCarthy, who has treated several C. auris patients at
Weill Cornell Medical Center in New York, described experiencing an unusual
fear when treating a 30-year-old man.

“I found myself not wanting to touch the guy,” he said. “I didn’t want to
take it from the guy and bring it to someone else.” He did his job and
thoroughly examined the patient, but said, “There was an overwhelming
feeling of being terrified of accidentally picking it up on a sock or tie
or gown.”

*The role of pesticides?*

As the C.D.C. works to limit the spread of drug-resistant C. auris, its
investigators have been trying to answer the vexing question: Where in the
world did it come from?

The first time doctors encountered C. auris was in the ear
<https://www.ncbi.nlm.nih.gov/pubmed/19161556> of a woman in Japan in 2009
(auris is Latin for ear). It seemed innocuous at the time, a cousin of
common, easily treated fungal infections.

Three years later, it appeared in an unusual test result in the lab of Dr.
Jacques Meis <https://www.ecmm.info/fecmm/fellows/meis-jacques/>, a
microbiologist in Nijmegen, the Netherlands, who was analyzing a
bloodstream infection in 18 patients from four hospitals in India. Soon,
new clusters of C. auris seemed to emerge with each passing month in
different parts of the world.

The C.D.C. investigators theorized that C. auris started in Asia and spread
across the globe. But when the agency compared the entire genome of auris
samples from India and Pakistan, Venezuela, South Africa and Japan, it
found that its origin was not a single place, and there was not a single
auris strain.

The genome sequencing showed that there were four distinctive versions of
the fungus, with differences so profound that they suggested that these
strains had diverged thousands of years ago and emerged as resistant
pathogens from harmless environmental strains in four different places at
the same time.

“Somehow, it made a jump almost seemingly simultaneously, and seemed to
spread and it is drug resistant, which is really mind-boggling,” Dr.
Vallabhaneni said.

There are different theories as to what happened with C. auris. Dr. Meis,
the Dutch researcher, said he believed that drug-resistant fungi were
developing thanks to heavy use of fungicides on crops.

Dr. Meis became intrigued by resistant fungi when he heard about the case
of a 63-year-old patient in the Netherlands who died in 2005 from a fungus
called Aspergillus. It proved resistant to a front-line antifungal
treatment called itraconazole. That drug is a virtual copy of the azole
pesticides that are used to dust crops the world over and account for more
than one-third of all fungicide sales
<https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3812019/>.

A 2013 paper
<https://journals.plos.org/plospathogens/article?id=10.1371/journal.ppat.1003633>
in Plos Pathogens said that it appeared to be no coincidence that
drug-resistant Aspergillus was showing up in the environment where the
azole fungicides were used. The fungus appeared in 12 percent of Dutch soil
samples, for example, but also in “flower beds, compost, leaves, plant
seeds, soil samples of tea gardens, paddy fields, hospital surroundings,
and aerial samples of hospitals.”

Dr. Meis visited the C.D.C. last summer to share research and theorize that
the same thing is happening with C. auris, which is also found in the soil:
Azoles have created an environment so hostile that the fungi are evolving,
with resistant strains surviving.

This is similar to concerns that resistant bacteria are growing because of
excessive use of antibiotics in livestock for health and growth promotion.
As with antibiotics in farm animals, azoles are used widely on crops.

“On everything — potatoes, beans, wheat, anything you can think of,
tomatoes, onions,” said Dr. Rhodes, the infectious disease specialist who
worked on the London outbreak. “We are driving this with the use of
antifungicides on crops.”

Dr. Chiller theorizes that C. auris may have benefited from the heavy use
of fungicides. His idea is that C. auris actually has existed for thousands
of years, hidden in the world’s crevices, a not particularly aggressive
bug. But as azoles began destroying more prevalent fungi, an opportunity
arrived for C. auris to enter the breach, a germ that had the ability to
readily resist fungicides now suitable for a world in which fungi less able
to resist are under attack.

The mystery of C. auris’s emergence remains unsolved, and its origin seems,
for the moment, to be less important than stopping its spread.

*Resistance and denial*

For now, the uncertainty around C. auris has led to a climate of fear, and
sometimes denial.

Last spring, Jasmine Cutler, 29, went to visit her 72-year-old father at a
hospital in New York City, where he had been admitted because of
complications from a surgery the previous month.

When she arrived at his room, she discovered that he had been sitting for
at least an hour in a recliner, in his own feces, because no one had come
when he had called for help to use the bathroom. Ms. Cutler said it became
clear to her that the staff was afraid to touch him because a test had
shown that he was carrying C. auris.

“I saw doctors and nurses looking in the window of his room,” she said. “My
father’s not a guinea pig. You’re not going to treat him like a freak at a
show.”

He was eventually discharged and told he no longer carried the fungus. But
he declined to be named, saying he feared being associated with the
frightening infection.
