Yellow fever/Talk

The question was asked why I deleted:

Health Sciences > Medicine > [Infectious Diseases]? > Yellow Fever

from the top of this article. Simple: because that's a classification scheme, and doesn't belong as part of the article itself, which is a fully independent subject. If you want to link to those other subjects, you can do that within the article text itself, or in a "See also" section.

I could argue that sometimes a surfer is taken to a given page by a search engine local or external and he/she might get some hierarchy perspective on the subject as well as some futher searching tip if the page is not the right one. Kpjas

That's roughly the purpose of RulesToConsider/Establish Context. I just don't think relying on one category scheme is a good way to do that. Back-linking to more general subjects--however many there may be--is better. Certainly you'll want to back-link to "disease" and "virus", and we do that. Maybe also to things like "epidemics" from the historical point of view, or to disease categories other than "infectious" (perhaps "hemorragic"?). Those linked subjects can further back-link to "medicine" or "biology" or whatever other topic they like; and those links can change over time as out thinking on the subjects and their categories change. --LDC
