Janitorial infection theory?
Answers
Explanation:
Focal infection theory is the historical concept that many chronic diseases, including systemic and common ones, are caused by focal infections. In present medical consensus, a focal infection is a localized infection, often asymptomatic, that causes disease elsewhere in the host, but focal infections are fairly infrequent and limited to fairly uncommon diseases.[1] (Distant injury is focal infection's key principle, whereas in ordinary infectious disease, the infection itself is systemic, as in measles, or the initially infected site is readily identifiable and invasion progresses contiguously, as in gangrene.)[2][3] Focal infection theory, rather, so explained virtually all diseases, including arthritis, atherosclerosis, cancer
Answer:
jan′i·to′ri·al (-tôr′ē-əl) adj.
Word History: In Latin iānus was the word for "archway, gateway, or covered passage" and also for the god of gates, doorways, and beginnings in general, known in English as Janus. Our month January—a month of beginnings—is named for the god. Latin iānitor, the source of our word janitor and ultimately also from iānus, meant "doorkeeper or gatekeeper." Probably because iānitor was common in Latin records and documents, it was adopted into English. In an early quotation Saint Peter is called "the Janitor of heaven." The term can still mean "doorkeeper," but in Scots usage janitor also referred to a minor school official. Apparently this position at times involved maintenance duties and doorkeeping, and the maintenance duties took over the more exalted tasks, giving us the position of janitor as we know it today
