COVID-19 and Fulminant Clostridium difficile Colitis Co-Infection.

The development of Clostridium difficile infection in COVID-19 patients is an understudied complication of the disease. Herein, we present the case of a 46-year-old man who developed severe healthcare-associated C. difficile infection leading to toxic megacolon and perforation in the setting of COVID-19 infection. It is important to continue to follow guidelines regarding antibiotics in healthcare settings to prevent such complications. LEARNING POINTS: Co-infection with Clostridium difficile and COVID-19 leads to poor outcomes with high mortality.C. difficile infection should be ruled out in COVID-19 patients who develop diarrhoea on antibiotic therapy.We should continue to follow the established guidelines of antimicrobial stewardship and remain vigilant for unexpected adverse effects. © EFIM 2021.
