HealthDay News — Candida auris cases and transmission have increased in the US in recent years, especially 2021, according to a study published online March 21 in the Annals of Internal Medicine.

Meghan Lyman, MD, from the US Centers for Disease Control and Prevention in Atlanta, and colleagues describe recent changes in the US epidemiology of C. auris occurring from 2019 to 2021, based on national surveillance data.

Through December 31, 2021, there were 3270 clinical cases and 7413 screening cases of C. auris reported in the US. The researchers found that each year, the percentage increase in cases grew, from an increase of 44% in 2019 to an increase of 95% in 2021. In 2021, colonization screening volume increased by more than 80% and screening cases increased by more than 200%. Seventeen states identified their first C. auris case during 2019 to 2021. In 2021, the number of C. auris cases that were resistant to echinocandins was about threefold higher than in each of the previous 2 years.

“The United States is not the only country to observe notable increases in recent years; other countries have reported additional cases since 2020 or reported their first cases or outbreaks,” the authors write.
