Usage notes
The terms, , /, and , as well as and , overlap on a semantic field and are often loosely used synonymously in their broad senses, although they are differentiable by narrower senses, as follows:
 * The word describes any disease or condition that is caused by an infectious agent (such as a bacterium, virus, parasite, or prion), including ones with person-to-person transmission/spread and ones without person-to-person transmission/spread. It is thus hypernymous to the following terms.
 * The words and /, as well as  and  (which are informal), describe the large subset of infectious diseases in which person-to-person transmission/spread (communication) can occur, including ones that are readily/easily spread and ones that are not readily/easily spread. They are thus hypernymous to the following term.
 * The word describes only those infectious diseases that are readily/easily spread, to the degree that preventing their spread is quite difficult unless a population is highly vaccinated against them (examples include measles and diphtheria).
