contact hypersensitivity
see allergic contact dermatitis.
indirect contact
that achieved through some intervening medium, as propagation of a communicable disease through the air or by means of fomites or another animal, e.g. an infection may be passed to animal A from animal B via animal C; animal C is an indirect contact.
