Transmission-Based Precautions are

to Standard Precautions for patients with documented or suspected infection or colonization with pathogens that can be transmitted by airborne, droplet, or contact routes. Any of the three types can be used in combination with the others. Equipment required for patient care, such as a thermometer, sphygmomanometer, and stethoscope, should be disposable, kept in the patient's room, and not used for other patients. The 2007 Centers for Disease Control and Prevention (CDC, updated 2019) Guidelines include a directive to put on personal protective equipment (PPE) when entering the room of a patient with transmission-based precautions, and to remove the PPE only when leaving the room. Consult the 2007 CDC (2007; updated 2019) Guidelines—Appendix A—for information related to the type and duration of precautions recommended for specific infections and conditions. These categories recognize that a disease may have multiple routes of transmission and require more than one type of precaution (Taylor et al., 2023).
