Candida auris (C. auris) is a species of fungus that causes serious infections in humans. It was first identified in 2009 in Japan and has since emerged as a global health concern due to its resistance to multiple antifungal drugs, its ability to spread easily in healthcare settings, and its association with high mortality rates.
Here's what you need to know about Candida auris:
-
Infections: C. auris can cause a variety of infections, ranging from superficial skin infections to life-threatening bloodstream, wound, and ear infections. It predominantly affects people with weakened immune systems, such as patients in intensive care units, those with chronic medical conditions, or individuals who have undergone recent surgery or taken broad-spectrum antibiotics.
-
Drug resistance: One of the main concerns with C. auris is its resistance to multiple antifungal drugs, making infections difficult to treat. In some cases, the fungus has shown resistance to all three major classes of antifungal medications: azoles, echinocandins, and polyenes.
-
Transmission: C. auris can spread easily between people and contaminated surfaces or medical equipment. It can persist on surfaces for extended periods, which contributes to its transmission in healthcare settings like hospitals and nursing homes.
-
Diagnosis: Accurate and timely identification of C. auris is crucial for effective treatment and containment. However, traditional diagnostic methods may misidentify it as other Candida species. Advanced laboratory techniques, such as matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry and molecular methods like polymerase chain reaction (PCR), are necessary for accurate identification.
-
Prevention and control: Infection control measures are vital to prevent the spread of C. auris. These include hand hygiene, environmental cleaning and disinfection, contact precautions, patient isolation, and surveillance of cases. Healthcare providers should be vigilant for potential outbreaks and report any suspected cases to public health authorities.
-
Treatment: Treatment options for C. auris infections are limited due to its drug resistance. A combination of antifungal medications may be necessary in some cases, depending on the susceptibility of the specific strain. Infections should be managed by a healthcare professional experienced in treating invasive fungal infections.
Candida auris is a drug-resistant fungus that poses significant challenges to healthcare systems worldwide. Awareness, early detection, and strict infection control measures are crucial in limiting its spread and impact on vulnerable patient populations.
