High fever with chills that does not get better after taking antibiotics may be a sign of Candida auris infection, and according to top US health agency, Covid-19 pandemic likely drove part of the surge in cases.
US cases of a dangerous fungus have tripled over just three years, and more than half of states have now reported it, according to a new study.
The Covid-19 pandemic likely drove part of the increase, researchers at the Centers for Disease Control and Prevention wrote in the paper published on Monday by Annals of Internal Medicine.
Hospital workers were strained by coronavirus patients, and that likely shifted their focus away from disinfecting some other kinds of germs, they said.
A high fever with chills that does not get better after taking antibiotics may be a sign of Candida auris infection.
People who are very sick, have invasive medical devices such as mechanical ventilators, or have long or frequent hospital stays are at particular risk for the infections, the report said.
"The rapid rise and geographic spread of cases is concerning and emphasises the need for continued surveillance, expanded lab capacity, quicker diagnostic tests, and adherence to proven infection prevention and control," study leader Dr Meghan Lyman said in a statement.

Candida auris (C. auris), an emerging fungus considered an urgent antimicrobial resistance (AR) threat, spread at an alarming rate in U.S. healthcare facilities in 2020-2021, according to data from CDC published in @AnnalsofIM. https://t.co/2GWYzWd0lj pic.twitter.com/n2JEIQLDjS— CDC (@CDCgov) March 21, 2023
Cases by year
The fungus, Candida auris, is a form of yeast that is usually not harmful to healthy people but can be a deadly risk to fragile hospital and nursing home patients.
It spreads quickly and can infect wounds, ears and the bloodstream.
Some strains are so-called superbugs, resistant to all three classes of antibiotic drugs used to treat fungal infections.
It was first identified in Japan in 2009 and has been seen in more and more countries.
The first US case occurred in 2013, but it was not reported until 2016. That year, US health officials reported 53 cases.
The new study found cases have continued to shoot up, rising to 476 in 2019, 756 in 2020, and 1,471 in 2021.
Doctors have also detected the fungus on the skin of thousands of other patients, making them a transmission risk to others.
Many of the first US cases were infections that had been imported from abroad, but now most infections are spread within the US, the authors noted.
