Scrubs are the sanitary clothing worn by surgeons, nurses, physicians and other workers involved in patient care in hospitals. Originally designed for use by surgeons and other operating room personnel, who would put them on when sterilizing themselves, or "scrubbing in", before surgery, they are now worn by many hospital personnel. Their use has been extended outside hospitals as well, to work environments where clothing may come into contact with infectious agents (veterinarians, midwives, etc.). Scrubs are designed to be simple (with minimal places for contaminants to hide), easy to launder, and cheap to replace if damaged or stained irreparably. In the United Kingdom, scrubs are sometimes known as theatre blues.
