External quality assessment (EQA) schemes to support European surveillance of Legionnaires’ disease 2019−2020 - Western Balkans and Turkey

This is the first EQA exercise for laboratories participating in surveillance from the ELDSNet network that has been
organised by ECDC since 2015 and the EQA format and arrangements have changed. The current EQA scheme
uses an outbreak scenario with a package of clinical and environmental samples for the participating laboratories to process, depending on their technical capacity and protocols.
