Document Summary
Hnn112 seminar note week 5: define the terms microorganism and health care associated infections. Living organism (such as a bacteria, fungi, viruses) too small to be seen with naked eye but visible under a microscope.

They also include infections acquired by patients in the hospital or facility but appearing after discharge, and occupational infections among staff. Contact is the most frequent mode of transmission of health care associated infections and can be divided into: direct and indirect. An example of contact transmitted microorganisms is noroviruses which are responsible for many gastrointestinal infections. Direct: involves direct body surface to body surface contact and physical transfer of microorganism between an infected or colonized person to another person by touch. Indirect: involves contact between a person and a contaminated object.
