Overview of sentinel systems for hospitalized severe acute respiratory infections (SARI) represented in the weekly EuroFlu surveillance bulletin




This document describes the SARI surveillance systems that are currently represented in the EuroFlu weekly bulletin. Countries whose SARI data are presented in the EuroFlu bulletin have SARI sentinel surveillance systems that meet the following two criteria: 

  • Hospitalized patients meeting a syndromic SARI case definition are routinely monitored, tested for influenza and reported to the national level on a weekly basis from a standard and generally stable number of sentinel hospitals.
  • There was consistent weekly reporting of epidemiological and virological data from the sentinel SARI system to the EuroFlu surveillance platform during the 2010/2011 influenza season.
