Description
In this request, we identified select complications of influenza, of increasing severity, among three separate cohorts: individuals diagnosed with influenza‐like illness (ILI), pneumonia and influenza (P&I), and medically attended acute respiratory illness (MAARI). We identified these cohorts in the Sentinel Distributed Database (SDD) during three time periods, corresponding to three influenza seasons.
The study periods were: July 1, 2014 to June 30, 2015; July 1, 2015 to June 30, 2016; and July 1, 2016 to June 30, 2017. We distributed this request to 14 Sentinel Data Partners on March 25, 2019.
