Scrubs are the sanitary clothing worn by physicians, nurses, dentists and other workers involved in patient care. 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.
The spread of methicillin-resistant Staphylococcus aureus (MRSA) has increased the use of scrubs but can give wearers a false sense of security that they are 'clean' when in fact they are as easily contaminated as any other clothing.
In contrast to the uniforms long required of nurses, surgeons did not wear any kind of specialized garments until well into the 20th century. Surgical procedures were conducted in an operating theater. The surgeon wore their own clothes, with perhaps a butcher's apron to protect their clothing from blood stains, and they operated bare-handed with non-sterile instruments and supplies. (Gut and silk sutures were sold as open strands with reusable hand-threaded needles; packing gauze was made of sweepings from the floors of cotton mills.)
In contrast to today's concept of surgery as a profession that emphasizes cleanliness and conscientiousness, up to the early 20th century the mark of a busy and successful surgeon was the profusion of blood and fluids on their clothes. The importance of dress as a badge of one's class in society was paramount and the processes behind the transmission of infection were the subject of controversy within the profession.

Asepsis is the state of being free from disease-causing micro-organisms (such as pathogenic bacteria, viruses, pathogenic fungi, and parasites). There are two categories of asepsis: medical and surgical. The modern day notion of asepsis is derived from the older antiseptic techniques, a shift initiated by different individuals in the 19th century who introduced practices such as the sterilizing of surgical tools and the wearing of surgical gloves during operations. The goal of asepsis is to eliminate infection, not to achieve sterility.
We address the need for robust detection of obstructed human features in complex environments, with a focus on intelligent surgical UIs. In our setup, real-time detection is used to find features without the help of local (spatial or temporal) information. ...
