Classically used in association with the "three Cs" of Measles infection: coryza, conjunctivitis, and cough.
This word may have its roots in the Greek Koryza, which is likely to be compounded from "kara" and "zeein". which are the noun for head and the verb, to boil. Coryza would therefore be a boiling over of the head. According to another source, coryza was an ancient Greek word denoting a fool; we use the term for a cold in the head, but the two are really synonymous ; the ancient Romans advised their patients to clean their nostrils and thereby sharpen their wits.
