Tracking Candida auris
Candida auris is an emerging fungus that presents a serious global health threat. In the United States, most cases of C. auris infection result from local spread within healthcare facilities in the same city or state. However, healthcare facilities should be on the lookout for new introductions of C. auris infection from patients who received healthcare elsewhere in the United States or abroad in areas with C. auris transmission.
C. auris was made nationally notifiable in 2018 pdf icon[PDF – 17 pages]external icon. Therefore, in states where C. auris is reportable, state and local public health departments should report cases to the National Notifiable Diseases Surveillance System (NNDSS). NNDSS data on C. auris are available through CDC WONDER and data.CDC.gov, but the data are incomplete because many states have not yet begun to submit C. auris data to NNDSS. Therefore, the case counts on this web page are more comprehensive than the NNDSS data. However, this web page relies on public health departments’ voluntary reporting of cases to CDC, so there may still be other C. auris cases that are unreported or undetected. In addition, case counts on this web page may differ from NNDSS data because NNDSS counts cases by residence state.

What are clinical cases?
Clinical cases of C. auris are classified according to the surveillance case definition established by the Council of State and Territorial Epidemiologists. Clinical cases are based on cultures or culture-independent diagnostic testing from specimens collected during the course of clinical care for the purpose of diagnosing or treating disease. Cases are categorized by the state of the healthcare facility where the specimen was collected.
What are colonization/screening cases?
Colonization/screening cases of C. auris are classified according to the surveillance case definition established by the Council of State and Territorial Epidemiologists. Screening is when swabs are collected from patients to determine whether or not they may be carrying the organism somewhere on their bodies without signs of active infection. Colonization means that these patients are found to be carrying C. auris on their bodies, even though they are not sick with the infection. Screening patients for C. auris colonization may be recommended when transmission or colonization of C. auris is suspected, to control the spread.
CDC is working closely with public health and healthcare partners to prevent and respond to C. auris infections. CDC encourages all U.S. laboratories that identify C. auris to notify their state or local public health authorities. State and local public health authorities can notify CDC about C. auris cases by emailing firstname.lastname@example.org. CDC’s AR Lab Network is available for assistance with C. auris identification and screening, to help improve detection and response to C. auris nationwide.
