A project run by ECDC since 2009 devoted to improving the quality of data collected by the national surveillance systems was planned to finish in 2011, but was still on-going at the end of 2015.
Projekt, ki ga je od leta 2009 vodil ECDC in je bil namenjen izboljšanju kakovosti podatkov, zbranih z nacionalnimi sistemi spremljanja, bi se moral po načrtih končati leta 2011, vendar je konec leta 2015 še vedno deloval.
