What does the term "isolation" mean in the context of infection control?

In the context of infection control, "isolation" refers to the practice of keeping a patient separated from others to prevent the spread of infection. This is a critical measure taken in healthcare settings to contain infectious diseases and protect both the healthcare staff and other patients. By isolating individuals who may be contagious, the risk of transmission is significantly reduced. This practice is especially important for patients diagnosed with communicable diseases that can spread through airborne, droplet, or contact routes.

The other options do not accurately capture the essence of isolation in infection control. Keeping a patient in an emergency room does not necessarily prevent the spread of infection, as patients might still come into contact with others. Administering antibiotics targets specific infections but does not relate to the physical separation aspect of isolation. Lastly, restricting visitors is a complementary measure for controlling the spread of infection, but it is not the primary definition of isolation itself.
