Disease Prevention
Changes began in the mid-1980’s
OSHA – before AIDS
CLIA – 1988
Federal regulations – law and safety
for patients and healthcare workers
 Called Standard Precautions

Indirect and Direct Contract
 Droplet infection – 20 feet or more
 Cough, sneeze, whistle
 Indirect – touching something that
has the microorganism on it
 Direct – contact with patient or their
body fluids
 What are possibilities for direct
contact?
