Transmission-based precautions are used when a patient:

Transmission-based precautions are employed in healthcare settings when a patient is suspected of having a contagious disease. These precautions are critical because they help prevent the spread of infectious agents in situations where standard precautions alone may not suffice.

When there is a suspicion of a contagious disease, such as an airborne, droplet, or contact infection, specific measures are implemented based on the type of transmission. This may include the use of specialized personal protective equipment (PPE), isolating the patient in a designated area, and employing enhanced sanitation protocols. These practices are vital in protecting healthcare workers, other patients, and visitors from potential exposure to pathogens.

The rationale behind using transmission-based precautions is to interrupt the chain of infection by minimizing contact with infectious agents and controlling their spread. This approach is essential in managing outbreaks and ensuring patient and staff safety within healthcare facilities.
