Health Communication comprises jobs that involve communication from within an organization to those outside an  organization, with a view to delivering a particular message, sharing an organizational identity, and shaping public relations.  These jobs can involve interaction with internal stakeholders; in ensuring that company rules and legal obligations are met, or  communicating organizational plans. They will also involve interaction with external entities in the form of press releases,  reports, promotional publications, videos, press conferences, and brochures.
