can c. diff be transmitted from person to person via saliva
C. difficile bacteria and their spores are found in feces. People can get infected if they touch surfaces contaminated with feces, and then touch their mouth. Healthcare workers can spread the bacteria to their patients if their hands are contaminated. For healthy people, C. difficile does not pose a health risk. The elderly and those with other illnesses or who are taking antibiotics, are at a greater risk of infection.
