  "description": "The Electronic Case Reporting Travel History profile establishes the core elements, extensions, vocabularies and value sets for representing the following for electronic case reporting:\n\n-  The Initial Case Report subject's travel history as a string, an address or a coded location.\r\n-  Observation.effectiveTime contains the date or period of time spent in the location.\r\n-  It is possible to have multiple Observation.components, each containing a different location, but there is only a single effectiveTime. This allows for cases where a patient cannot remember exact dates of travel (e.g. I traveled to London, Paris, and Berlin in July and August 2016). However, most uses will involve a single component (location).\r\n-  Free text describing the travel history details and location can be entered using the Observation.component.valueCodeableConcept.text element\r\n-  Use component.codeableConcept to record a coded location\r\n-  Use component.extension to record a specific address",
