Research uncovers hidden spread of one of the most common hospital-associated infections

University of Utah Health
Peer-Reviewed Publication

C. difficile (C. diff) is one of the most common and contagious hospital-acquired infections. Research has found that C. diff spreads more than three times more than previously thought. C. diff can spread covertly from surface to surface and remain undetected for weeks until it infects a patient. The results could spur more rigorous preventive measures that stop hidden spread of the disease.
