  2. Definition

    This codelist was taken from OpenCodelists, created by OpenSAFELY. We recommend viewing this Phenotype on the OpenCodelist website to view the most recent version.

    Codelist created to identify Influenza in primary care with as much sensitivity as possible

  3. Methodology

    Codelist should be used in conjunction with Influenza Identification (Primary Care), if a patient does not have a code within said list, they must have 2 codes from the maximally sensitive codelist, or prescriptions codelist, within two weeks of each other, or they must fit the criteria of the WHO Influenza Like Illness (ARI, fever, cough). They must not have any codes present in the exclusion list. Codelist checked by Charlotte Warren-Gash. To see full outcome phenotypes see Github issue in references
