What Is Candida Auris?

In recent years the Centers for Disease Control and Prevention has drawn attention to a source of increasing concern for nursing home residents: Candida auris, also known as C. auris, a fungus that causes "bloodstream infections and even death" in those it affects. Like many infections, C. auris infections are particularly dangerous for those who are already suffering from other conditions. Described by the CDC as “a serious global health threat,” C. auris poses a special risk for nursing home residents. What makes C. auris so dangerous? A few things. The CDC notes that the fungus is frequently resistant to numerous antibiotic medications; that it is “difficult to identify with standard laboratory methods”; and that it is even prone to misidentification by laboratories without certain technology. This places elderly populations, especially those in nursing homes and other long-term care facilities, at heightened risk. A New York Times report published in September 2019 described a June 2019 study that found “patients and residents in long-term care settings have alarmingly high rates of drug-resistant colonization, which means they carry the germs on their skin or in their bodies, usually without knowing it, and can pass them invisibly to staff members, relatives or other patients.” The study in question “focused on Southern California,” finding that 85% of nursing home residents “harbored a drug-resistant germ.” The CDC has also found that the infection proliferates in long-term healthcare centers The Times reported that 800 cases of C. auris infection have been identified in the US since the fungus was first reported here in 2015. In August 2019, the CDC updated that count to 806. That includes 388 confirmed cases in New York; 227 confirmed cases in Illinois; 137 confirmed cases in New Jersey; 24 confirmed cases in Florida; and five confirmed cases in California. The Times attributes C. auris’ easy spread through nursing homes to a few factors, in addition to the prevalence of nursing home patients on multiple antibiotics to which the infection has already developed a resistance. Nursing homes are frequently understaffed and under-resourced, according to the Times, and struggle to "enforce rigorous infection control." They often cycle infected persons in and out of hospitals, putting those hospitals' patients at risk of the infection too. One health expert told the Times, "You'll never protect hospital patients until the nursing homes are forced to clean up." Basic hygienic measures, such as “using disposable gowns and latex gloves,” are essential to combating the infection, yet often unfollowed by long-term care centers, according to the Times. Experts also attribute the infection's spread in the US to healthcare economics "that push high-risk patients out of hospitals and into skilled nursing homes." Under the US's healthcare system, these experts told the Times, “nursing home facilities are reimbursed at a higher rate to care for these patients… providing an economic incentive for poorly staffed or equipped facilities to care for vulnerable patients.” Public health law requires nursing home facilities to develop and implement robust, effective programs to prevent and control infection; they are also required to maintain adequate staffing and sanitation protocols that provide patients with the highest possible well-being. Nursing homes that fail to comply with health and safety requirements may be subject to sanctions that range from citations to monetary penalties.
