  "definition" : "A role played by an entity that has been exposed to a person or animal suffering a contagious disease, or with a location from which a toxin has been distributed.  The player of the role is normally a person or animal, but it is possible that other entity types could become exposed.  The role is scoped by the source of the exposure, and it is quite possible for a person playing the role of exposed party to also become the scoper a role played by another person.  That is to say, once a person has become infected, it is possible, perhaps likely, for that person to infect others.\\r\\n\\n                        Management of exposures and tracking exposed parties is a key function within public health, and within most public health contexts - exposed parties are known as \\\"contacts.\\\"",
