Deadly germs, Lost cures: A Mysterious Infection, Spanning the Globe in a Climate of Secrecy. msn.com See Also: arutzsheva
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 in Spain, forced a prestigious British medical center to shut down its intensive care unit, and taken root in India, Pakistan and South Africa .
Recently C. auris reached New York , New Jersey and Illinois, leading the federal Centers for Disease Control and Prevention to add it to a list 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, making 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 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.
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.”
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.”
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.
MUST LISTEN TO THIS:
Mosquito Bots: "[…]a larger concern is the threat of the nanoscale robots, or nanobots because they are "the technological equivalent of biological weapons.” The author said controlling these "smart nanobots" could become an issue since if lost, there could be potentially millions of these deadly nanobots on the loose killing people indiscriminately.
