Your image seems misleading, as it seems to report greater than 100% survival rate for C. auris.
There are some basic truths about pathogens that are generally applicable to C. auris as for all diseases. The cleaner and more sterile the environment, the more inviting of pathogens it is. Pathogens are generally (I have no specific information for C. auris) non-competitive with other organisms, due to their virulence. So environments that allow competing organisms to occupy the niches necessary to populations of pathogens tend to support only low numbers of the less competitive pathogens, because the more robust species out-compete pathogens for specific resources.
I cannot address C. auris specifically, but copper is an extraordinarily competent biocide. It is probable that if hospitals simply replaced stainless steel with copper, the majority of opportunistic infections would not occur. Where the additional strength of stainless is required, copper plating would still be possible, and effect the biological control native to copper.
I am not confident that hospitals are on the verge of quarantine. Were there significant spread of C. auris to constitute a desperate public health crisis and hospitals a primary vector, which is what would make quarantine of hospitals likely, I expect more people would be telling us about it. Note: I am not referring to the enemedia, but to social media, and the reports of individuals impacted.
The language and tone of the quote from the NHF really does not inspire credibility, particularly when illustrated by a picture that alleges greater than 100% survival of C. auris from immune cell response. I can't even imagine a rational mechanism that might conceivably create such an effect... White blood cells being converted to fungal cells? Serving as fungal nurseries? The overall sense of threat from C. auris I am left with as a result of my assessment of the image and quote from the NHF is reduced, rather than increased, because of these credibility issues.
Yes, I've heard very good things about copper also, lately. I didn't realize colloidal silver wasn't sufficient for almost any of these pathogens until recently.
I can only assume the chart is showing that C. Auris actually thrives MORE in that standard fungicide environment.
