This multi-resistant fungus becomes an urgent threat to global health

The spread of Candida auris in hospitals around the world highlights a new potential hazard: that of antifungal-resistant fungi, such as antibiotic-insensitive "superbugs". A very disturbing phenomenon and yet put under the rug by health facilities.

His name is Candida auris. This yeast Microscopic is a growing concern in hospitals around the world. Because, like bacteria multidrug-resistant 700,000 people dead in the world, the mushroom C. auris seems to withstand most of the How do antifungals work?

Since the first case identified in 2009 in Japan, the disease spread to the whole planet: South Korea, India, China, Colombia and Venezuela, United States, Canada and Europe … In the United States, 587 cases have been identified since the arrival of pathogenic in 2013, including 309 in New York alone. In Europe, the European Center for Disease Prevention and Control (ECDC) also warns aboutworrying increase in the number of cases, with 620 infections recorded between 2013 and 2017 in six countries, the majority in Spain and the United Kingdom (two in France).

Most cases are patients at immune system weakened or having undergone an operation In a hospital. The fungus is introduced by a wound, the ears or the urinary tract and then colonizes the blood system. Examples of symptoms

According to the different studies, the mortality rate would rise from 30% to 57% once the fungus reaches the blood system.


Do not frighten patients

This disturbing epidemic is an increase in an endemic disease or the appearance of a large number of patients where the disease was … "data-url =" / health / definitions / life-epidemic-3837 / " data-more = "Read more">epidemic yet remains largely under radar. On the one hand, identification tests remain quite complex and not implemented. Some hospitals take more than a year to discover the presence of the fungus, which has meanwhile had the opportunity to infect other patients. Infected material and people remain contagious for several months even after drastic hygiene measures. But the epidemic is mainly the subject of a climate of secrecy: neither the Royal Brompton Hospital of London, which had to close a dozen days in 2016 for decontamination, nor the polyclinic La Fe de Valence in Spain, in which 140 people were infected in 2016 and 2017, did not think it useful to make a public communication: no need to scare patients, argue their officials. " Healthcare institutions fear losing their reputation Explains infectious disease specialist Silke Schelenz in the New York Times.

Massive use of fungicides in question

Candida auris is not the only case of mushroom resistant. In the 2000s, Aspergillus fumigatus had already proven resistant to itraconazole, an antifungal that was thought to be effective against all mushrooms. There is no point in pouring into psychosis : only a dozen mushrooms are potentially dangerous for humans over five million species The species is the fundamental entity of classifications, which brings together living beings with a set of morphological, anatomical, … " url = "/ planet / definitions / zoology-species-2261 /" data-more = "Read more">cash who populate the planet. But if these pathogens become insensitive to more and more treatments, one could well witness a drama as extensive as that of "superbugs". The researchers think that it is the same mechanism of resistance which is at work: like the role of antibiotics
Antibiotics are used in medicine (and veterinary medicine) to fight infections … "data-image =" 2/0 / 720b0754f0_50034470_miel-tartine-antibiotique-dr-04.jpg "data-url =" / health / definitions / antibiotic-medicine-2992 / "data-more =" Read more ">antibiotics, antifungals are massively spread: Season fields of the potato

So what to do? The ECDC advocates in particular an improvement of the prevention, with a watch on the reports, the strict isolation of the infected patients or the general measures of hygiene. Better information between hospitals must also be put in place, including a report on the transfer of a patient carrier.

What you must remember

  • Candida auris is a yeast that has developed resistance to the main known antifungal treatments.
  • It infects fragile patients in hospitals that seem quite helpless by the phenomenon.
  • This new threat is reminiscent of multidrug-resistant bacteria, causing 700,000 deaths per year.
