Acute Respiratory Illness (Secondary Care) ICD-10
A collection of non-specific codes relating to acute respiratory illnesses (ARI) not including pathogen specific codes. Adapted from WHO definition of Influenza-like-illness, whereas with the primary care ARI codelist (see references) fever and cough can be used to build a build a full ILI profile, in secondary care this is more difficult so just the ARI codelist is used. To be used to detect influenza cases with more sensitivity, rather than specificity.
