By Clara Harter, Los Angeles Times LOS ANGELES — A deadly, drug-resistant fungus that preys on the sick and old is continuing to spread in hospitals and senior care facilities across the country, killing more than 1 in 3 infected. Candida auris, a type of yeast that can cause life-threatening illn ess, was first identified in the U.S. in 2016 with 52 infections reported across the country, according to the U.S. Centers for Disease Control and Prevention. The number of cases has more than doubled annually, hitting 4,514 in 2023, the latest year the CDC has data available. During this same period, California reported 1,566 infections, more than any other state. Related Articles Black women’s hair products are in the safety spotlight.

Now, there are signs that the fungus is once again on the move. The Georgia Department of Public Health recently reported a surge in cases in healthcare facilities, and a recent study found an alarming rate of spread in Florida hospitals. C. auris spreads through direct contact with colonized or infected individuals, contaminated surfaces and medical equipment. A colonized person has the fungus on their skin but does not experience symptoms. In an infected person, the fungus invades the body and causes symptoms such as fever, chills, sepsis and organ failure. The risk of infection is especially high for patients with catheters, breathing tubes or feeding tubes because they create direct entry points for C. auris to enter the bloodstream or lungs. Most healthy people are not at serious risk of complications from infections. “Most of the patients that get infections with Candida auris are themselves pretty sick to start with,” said Stuart Cohen, chief of infectious diseases at UC Davis. “This is something that can push people over the edge and become life-threatening.” Studies have found C. auris infections have a mortality rate of 30% to 60%. To prevent the spread of the disease, most California hospitals have implemented screening procedures for patients transferred from high-risk healthcare settings. Those found to have C. auris are then isolated from the rest of the hospital. “The goal is, first and foremost, to keep the people in your hospital safe,” Cohen said. “When somebody comes in for a procedure, they’re not expecting to go home with a life-threatening illness or having spent time in an ICU from a hospital infection.” Most common disinfectants do not kill C. auris, which can live on surfaces for weeks. There are, however, specialized products that hospitals can use to eliminate the yeast. ©2025 Los Angeles Times. Visit at latimes.com.
