Candida auris was discovered in 2009. CRISPR in 2012. Candida auris itself could not have been the result of any CRISPR editing experiment. Maybe you are suggesting that a particular strain of Candida auris is such a result. This is difficult to refute without an actual genomic analysis. But a much simpler explanation exists: Candida auris is nasty in itself. It does not need genetic engineering to be nasty. It is simply spreading in hospitals among immunocompromised patients because this is what Candida auris does. Per wikipedia [1]:

  > Often, candidiasis is acquired in hospitals by patients with weakened immune systems. C. auris can cause invasive candidiasis (fungemia) in which the bloodstream, the central nervous system, and internal organs are infected. It has attracted widespread attention because of its multiple drug resistance. Treatment is also complicated because it is easily misidentified as other Candida species.
