Overview

My current research is focused on Clostridium difficile infection in children with cancer. Clostridium difficile is a common bacterium in the human gut that usually does not cause infection but in certain circumstances can cause diarrhea. It is significant because it can easily spread from patient to patient in hospitals if infection prevention measures and environmental cleaning practices are suboptimal. We have noted that a higher proportion of oncology patients have this infection compared to other hospitalized patients. We aim to determine whether patients get the infection in hospital or if they come to the hospital with it. This information will help us understand the true burden of C. difficile infection in oncology and improve the quality of care provided to these patients.
