Here at Violet Defense, we are passionate about protecting our world from germs. As part of this journey, our blog helps us all to become more “germ aware” about the risks that germs pose to our health and wellness in everyday places, but more importantly how UV light has the power to help us fight this war against harmful bacteria and viruses.



UV Disinfection: New Tool in Fight Against Fungal Superbug

Antibiotic resistance has been of growing concern across the globe, causing over 2 million infections and 23,000 deaths here in the United States annually.  In recent years, a new “serious global health threat” has emerged according to the Centers for Disease Control and Prevention (CDC), a fungal superbug named Candida auris (C. auris).

 With our patented UV disinfection technology, we can help protect against this deadly fungus, killing up to 99.9% of C. auris, as proven by independent laboratory testing.    

The C. auris Threat

 C. auris is a “novel yeast that is behaving in unexplained and concerning ways causing severe disease in countries across the globe,” says Dr. Tom Chiller, Chief of Mycotic Diseases Branch at the CDC.  While first identified in Japan in 2009, C. auris has been making its way quickly around the globe, now in 30 countries, including the United States which has seen over 650 clinical cases.  As it is multi-drug resistant, it has proven highly lethal, with more than 1 in 3 patients dying within one month of an infection.  

C. auris cases

The nature of the fungus has made it capable of spreading between patients and causing outbreaks, in part due to the ability of C. auris to colonize on patients for extended periods of time, as well as survive on surfaces for a month or more.  In patient rooms, C. auris has been cultured on high touch surfaces, such as hospital beds, as well as locations further away from patients (i.e. windowsills).  It’s also been found on mobile equipment, such as glucometers, temperature probes, ultrasound machines, and more. 

Infection Control Against C. auris

Unfortunately, according to the CDC, preliminary testing for C. auris has indicated that quaternary ammonium compounds, disinfectants commonly used in healthcare settings, may be insufficient against this pathogen.  Therefore, new tools are needed to help prevent the spread of this fungus and help protect patients and staff from this threat.

Since the company was founded, we have been on a journey to help protect people in everyday spaces, including healthcare facilities, against harmful pathogens, particularly those that have grown resistant to the traditional ways of dealing with them.  C. auris represents another important pathogen for us to address, and our recent lab testing confirms that we can address it quite effectively with our patented UV technology design.

 An EPA and FDA GLP-Compliant, ISO 17025 Accredited Testing Laboratory evaluated the effectiveness of our UV disinfection technology against C. auris.  The testing demonstrated that our technology can kill up to 99.9% of C. auris using a single one of our UV disinfection units.  Our UV disinfection technology has been previously shown to kill up to 99.9% of MRSA, Norovirus, E. coli, Salmonella, and C. diff.
