In 1847, Austrian physician Ignaz Semmelweiss proved that washing hands drastically reduced deaths from sepsis on maternity wards, and he published those findings in his book Etiology, Concept and Prophylaxis of Childbed Fever. Health care acquired infections (HAIs) are almost completely preventable, yet more than 150 years after Dr. Semmelweiss’ observations, HAIs are responsible for an estimated two million infections and almost 100,000 deaths (Centers for Disease Control and Prevention, 2011) each year in the United States alone.
