The term often refers to those practices used to promote or induce asepsis in an operative field of surgery or medicine to prevent infection . </P> <P> The goal of asepsis is to eliminate infection, not to achieve sterility . Ideally, a surgical field is sterile, meaning it is free of all biological contaminants (e.g. fungi, bacteria, viruses), not just those that can cause disease, putrefaction, or fermentation . At present, there is no method to safely eliminate all of a patient's contaminants without causing significant tissue damage . </P>
