Quiz: Understanding Hospital-Acquired Infections
During the 1830s, hospitalism was a term used to identify a growing problem in hospitals throughout northern Europe. It referred to diseases contracted by patients because of their stay in a hospital. Health officials at that time believed hospitalism was caused by poor ventilation; few believed in germs or cross contamination. Today, hospitalism is known as nosocomial or hospital-associated (or -acquired) infections (HAIs). We now know that along with other measures, hygienic cleaning can help prevent these illnesses.
