In addition the following codes were added:\n\t- Telephone consultation suspected influenza A virus subtype H1N1\n\t- Telephone consultation for suspected swine flu\n\t- Encephalitis due to influenza\\-specific virus not identified\n\t- Encephalitis due to influenza\\-virus identified\n- Codes from Quality Outcome Framework (QOF) were examined and no relevant terms were found\n- Codes from SNOMED were taken by searching for relevant influenza terms and a list was created.\n\n\nThese 2 lists were mapped into CTV3 by TPP to create one list. This list was examined by 2 people and the following logic applied (see github issue for more detail):\n\n",
