The risk of transmission of pathogens and subsequent infection in healthcare facilities is substantial. Pathogens may be transmitted from other patients, the hospital personnel, and/or the hospital environment. The risk is variable and depends on a patient's immune status, the local prevalence of various pathogens, and the infection control practices and antimicrobial stewardship utilized during hospitalization.

Issues related to precautions devised to minimize risk for transmission of infection are reviewed here.

Issues related to the prevention of specific infections, prophylaxis after exposure to bloodborne pathogens, and immunizations for healthcare workers are discussed in detail separately. (See related topics.)


Standard precautions should be followed for the care of all patients (table 1) even when the presence of an infectious agent is not apparent or is thought to be minimal [1].

Standard precautions entail [1-3]:
