Scrub tops are a kind of defensive clothing created to be worn by medical staff during times when they will likely come into contact with an infectious substance or bodily fluid. They shield the wearer and help them form a barrier between them and the infectious person close-by. Have you ever thought about why hospital employees wear scrubs and why they come in so many different colours? Well, when we visit a hospital we see a bunch of different workers in different colour uniforms and often wonder, why are they worn? Scrubs have become a medical essential and the purpose of scrubs has changed completely. It is a part of everyday life for medical professionals.
