Dr.JMack | ER Doctor on Instagram: "How awesome is my sister!?? P.S. Clostridioides difficile is extremely contagious, can live on surfaces for a long time, and can’t be killed with hand sanitizer alone (need to wash hands due to tough outer shell called a spore). As a result, it’s one of the most common hospital-acquired (nosocomial) infections and is an increasingly frequent cause of morbidity and mortality among older adult hospitalized patients."
