<i>Clostridioides difficile</i> infection in coronavirus disease 2019: an underestimated problem?

Abstract

We observed a higher incidence of CDI in patients with COVID‑19. Antibiotic therapy was a relevant risk factor for CDI, although its effect was weak. Other drugs used during the pandemic were not found to have an impact on disease development. Possible causes of CDI may include fecal microbiota disruption by SARS‑CoV‑2 infection, but further research is needed to validate this hypothesis.
