==''Candida auris'' overview|Overview==
''Candida auris'' is a fungus, recently described as a rare cause of fungal infection with significant resistance to antifungal medications.<ref name="pmidPMID 24357342">{{cite journal| author=Chowdhary A, Anil Kumar V, Sharma C, Prakash A, Agarwal K, Babu R et al.| title=Multidrug-resistant endemic clonal strain of Candida auris in India. | journal=Eur J Clin Microbiol Infect Dis | year= 2014 | volume= 33 | issue= 6 | pages= 919-26 | pmid=PMID 24357342 | doi=10.1007/s10096-013-2027-1 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=24357342  }} </ref> It was first described in the year 2009 in Japan,<ref name="pmidPMID 27832049">{{cite journal| author=Vallabhaneni S, Kallen A, Tsay S, Chow N, Welsh R, Kerins J et al.| title=Investigation of the First Seven Reported Cases of Candida auris, a Globally Emerging Invasive, Multidrug-Resistant Fungus - United States, May 2013-August 2016. | journal=MMWR Morb Mortal Wkly Rep | year= 2016 | volume= 65 | issue= 44 | pages= 1234-1237 | pmid=PMID 27832049 | doi=10.15585/mmwr.mm6544e1 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=27832049  }} </ref> and since then, reports of ''C. auris'' infection has been published from several countries.<ref name="pmidPMID 27832049" /> Serious and prolonged outbreaks have been documented with data showing an innate resilience of ''C.auris'' for survival, persistence in the clinical environment with the ability to rapidly colonize patient's skin, and high transmissibility within the healthcare system.<sup>[[Sandbox:FB|[4]]]</sup> The precise mode of transmission within the healthcare facility is unknown.<ref name="cdc1">Centers for Disease Control and Prevention. https://www.cdc.gov/fungal/diseases/candidiasis/candida-auris-alert.html Accessed on November 11th, 2016. </ref><ref name=cdc2>Public Health England.https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/534174/Guidance_Candida__auris.pdf.

==''Candida auris'' historical perspective|Historical Perspective==
* ''C. auris'' was first described in 2009 after being isolated from external ear canal discharge of a patient in Japan.<ref name="pmidPMID 27832049" />
* ''C. auris'' was incidentally found by molecular identification of bloodstream isolates of unidentified yeasts recovered in 1996, suggesting the paucity of isolation of ''C. auris'' may partly reflect the difficulty in identifying the specie.<ref name="pmid21715586">{{cite journal| author=Lee WG, Shin JH, Uh Y, Kang MG, Kim SH, Park KH et al.| title=First three reported cases of nosocomial fungemia caused by Candida auris. | journal=J Clin Microbiol | year= 2011 | volume= 49 | issue= 9 | pages= 3139-42 | pmid=21715586 | doi=10.1128/JCM.00319-11 | pmc=3165631 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=21715586  }} </ref>
* The occurrence of ''C. auris'' in nine countries on four continents since 2009 has been reported.<ref name="cdc1" />
* ''C. auris'' infections have most commonly been hospital-acquired and occurred several weeks into a patient’s hospital stay.<ref name="cdc1" />
* It has been documented to cause infections in patients of all ages.<ref name="cdc1" /><ref name="pmid21715586" />
* Patients were found to have similar risk factors for infections with other ''[[Candida]]'' spp.<ref name="cdc1" />
==''Candida auris'' pathophysiology|Pathophysiology==
* High potential for nosocomial horizontal transmission.<ref name="pmidPMID 27777756" /><ref name="pmidPMID 27452195">{{cite journal| author=Calvo B, Melo AS, Perozo-Mena A, Hernandez M, Francisco EC, Hagen F et al.| title=First report of Candida auris in America: Clinical and microbiological aspects of 18 episodes of candidemia. | journal=J Infect | year= 2016 | volume= 73 | issue= 4 | pages= 369-74 | pmid=PMID 27452195 | doi=10.1016/j.jinf.2016.07.008 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=27452195  }} </ref>
