Which two factors determine the need for Transmission-Based Precautions beyond Standard Precautions?

The important idea is that Transmission-Based Precautions are added based on what the infectious agent is and how that agent spreads. Knowing the suspected or known organism tells you about its behavior and potential complications, while knowing how it moves from one person to another tells you which barrier or control measure will effectively block that route. Together these two factors determine whether you use airborne, droplet, or contact precautions (and what PPE or room setup is needed). The patient’s age, the time of day, or where the care is being provided do not by themselves tell you which precautions are necessary. For example, airborne agents require different measures than those spread by direct contact, and the decision hinges on the agent and its transmission route.
