Drug-resistant superbug thriving

Candida auris is a superbug, a pathogen that can evade drugs made to kill it—and early signs suggest the COVID-19 pandemic may be propelling infections of the highly dangerous yeast. That’s because C. auris is particularly prominent in hospital settings, which have been flooded with people this year due to the coronavirus.

The superbug sticks stubbornly to surfaces such as sheets, bed railings, doors, and medical devices—making it easier to colonize skin and pass from one person to another. Moreover patients who have tubes that go into their body, such as catheters or ones for breathing or feeding, are at the highest risk for C. auris infections, and these invasive procedures have become more common because of the respiratory failure associated with COVID-19.

“Unfortunately, there have been places where we’ve seen a resurgence of C. auris,” says Tom Chiller, head of the mycotic diseases branch at the U.S. Centers for Disease Control and Prevention. “We’ve also seen it get into some of the acute care hospitals and also into some COVID-19 units … the concern there is that once it sets up shop in a place, it’s hard to get rid of.”
