Multiple strains causing oral infection in COVID-19 patients under corticosteroids and antibiotic therapy: An observational study.

Introduction: The occurrence of oral candidiasis (OC) is expected in patients with COVID-19, especially those with moderate to severe forms of infection who are hospitalized and may be on long-term use of broad-spectrum antibiotics or prolonged corticosteroid therapy. We aimed to characterize clinical conditions, the prevalence profile of species, and outcomes of COVID-19 patients with OC.

Methods: In this observational study, oral samples were obtained from COVID-19 patients suspected of OC admitted to Razi teaching hospital.
