It is about the fungus Candida auris, which the World Health Organization (WHO) has included in the list of pathogens posing a critical threat. Here is a detailed analysis of the situation, formatted as a popular science article. Superbug Candida auris: An Invisible Pandemic Gaining Strength in Europe The term “superbug” refers to the pathogenic yeast fungus Candida auris, which shows a worrying resistance to most existing antifungal drugs. Since its first description in 2009 (isolated from a patient's earwax in Japan, hence the name “auris” — ear), this microorganism has rapidly spread around the world, becoming one of the most dangerous hospital-acquired infections. In Europe, with its dense population and active migration flows, outbreaks of C. auris are becoming more frequent, causing concern among epidemiologists and practicing physicians. Unique danger and resistance of the pathogen The main feature of Candida auris, making it a “superbug,” is its multiple drug resistance. Many strains show resistance to three main classes of antifungal drugs (azoles, echinocandins, and polyenes), which makes treatment of the infection extremely difficult and sometimes impossible. In addition, the fungus is extremely resilient in the external environment. Unlike its more well-known relative Candida albicans, C. auris can persist on surfaces in hospital rooms (furniture, equipment, walls) for a long time, is resistant to the action of many disinfectants based on quaternary ammonium compounds, and can be transmitted not only from person to person but also through contaminated objects. High-risk groups and clinical picture For a healthy person with an intact immune system, Candida auris generally does not pose a serious threat. The main risk group consists of critically ill patients in hospitals: Patients in intensive care units and intensive care units. People with weakened immunity (after chemotherapy, organ transplantation, with HIV). Patients with multiple catheters or ... Read more
