Cross Infection

CROSS INFECTION

Cross infection refers to the transmission of a pathogenic organism from one person to another. It is a common and important mode of infection with many varieties of organisms, including streptococcal and other bacterial diseases, viral hepatitis A and some other fecal-oral infections, such as scabies, fungus infections, pinworms, and roundworms. Cross infection can occur in kindergartens, day-care centers, schools, prisons, military barracks, places of employment, and other settings where individuals and groups interact with one other. When it happens in a medical setting, such as a hospital or nursing home, it is sometimes called nosocomial infection. But this is a misnomer; nosocomial infections may be acquired in other ways, including hospital staff or inadequately sterilized surgical instruments.

Cross infection is a potential problem in all institutional settings. It is an ever-present problem in kindergartens and day-care centers, which should always observe procedures that can minimize this type of infection and limit the effects of such infections. These procedures include constant surveillance, maintenance of sanitary conditions, and prompt intervention whenever an infection is detected. The best way to prevent cross infections is by rigorous observance of personal hygiene at all times, and through the use of barrier nursing, sanitary practices, and other pertinent procedures.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
