are infection control guidelines designed to protect workers/patients from exposure to diseases spread by blood and certain body fluids.
Always treat blood, body fluids, broken skin and mucous membranes as if they were infected
Always follow Universal Precautions because you cannot tell by looking at a person whether they have a contagious disease
