Isolation precautions aim to stop the spread of infection by creating barriers between the infected patient and others. This means using a private room when possible, wearing appropriate personal protective equipment, practicing meticulous hand hygiene, and ensuring proper environmental cleaning. The precautions are chosen based on how the pathogen spreads—whether by direct contact, droplets, or airborne transmission—to interrupt transmission to other patients, healthcare workers, and visitors while still allowing the patient to receive care. It’s about reducing transmission from the patient, not about isolating equipment, the whole building, or staff who aren’t involved in direct care.
