C. auris is a mysterious and dangerous fungal infection that is among a growing number of germs that have evolved defenses against common medicines. Here are some basic facts about it.

A mysterious and dangerous fungal infection called Candida auris has emerged around the world. It is resistant to many antifungal medications, placing it among a growing number of germs that have evolved defenses against common medicines. Here are some basic facts about it.

Candida auris is a fungus that, when it gets into the bloodstream, can cause dangerous infections that can be life-threatening. Scientists first identified it in 2009 in a patient in Japan. In recent years, it has emerged around the world, largely in hospitals and nursing homes. There have been 587 C. auris cases reported in the United States, according to the Centers for Disease Control and Prevention, most of them in New York, New Jersey and Illinois.

C. auris is often resistant to major antifungal drugs that are typically used to treat such infections. The C.D.C. says that more than 90 percent of C. auris infections are resistant to at least one such drug, while 30 percent are resistant to two or more major drugs. Once the germ is present, it is hard to eradicate from a facility. Some hospitals have had to bring in special cleaning equipment and even rip out floor and ceiling tiles to get rid of it.

People with compromised or weakened immune systems are the most vulnerable. This includes elderly people, and also people who are already sick; in at least one case, newborns were infected at a neonatal unit. People with weakened immunity are likely to have more trouble fighting off an initial invasion by C. auris and also are likely to be in settings, like hospitals and nursing homes, where the infection is more prevalent.

The rise of C. auris has been little publicized in part because it is so new. But also, outbreaks have at times been played down or kept confidential by hospitals, doctors, even governments. Some hospitals and medical professionals argue that because precautions are taken to prevent the spread, publicizing an outbreak would scare people unnecessarily.

The symptoms of C. auris — fever, aches, fatigue — are not unusual, so it is hard to recognize the infection without testing. The good news is that the threat of becoming sick with C. auris is very low for healthy people going about their daily lives. If you or a loved one is in a hospital or nursing home, you can ask if there have been cases of Candida auris there. If so, it is reasonable to request that proper “infection control” precautions are taken. In the United States, this question would be most relevant in New York, New Jersey and Illinois, specifically Chicago, where the germ has been concentrated.
