Background
The Communicable Disease Threats Report (CDTR) is a weekly bulletin published every Friday by the European Centre for Disease Prevention and Control (ECDC). Launched in 2017, it is the ECDC's primary operational communication product for EU and EEA public health authorities, providing a consolidated assessment of active communicable disease threats, outbreak updates, and emerging risks. Each CDTR edition covers confirmed and suspected outbreaks with cross-border transmission potential, along with rapid risk assessment summaries and guidance links.
The CDTR is distributed directly to EU member state health ministries, national public health institutes, and the European Commission. It is also published publicly on the ECDC website each Friday, making it a reference source for researchers and journalists covering European outbreak surveillance. The bulletin is distinct from the ECDC's longer-form Rapid Risk Assessments (RRAs), which provide deeper analysis of individual threats, and from the Annual Epidemiological Reports, which compile full-year disease burden data.
In the cross-topic context, the CDTR appears in Lowdown whenever EU outbreak surveillance is relevant. For any European infectious disease story, the CDTR is typically the primary institutional source alongside national health authority communications.
The CDTR featured the MV Hondius Andes hantavirus cluster in its May 2026 editions, tracking the evolving case count and coordinating with ECDC's own surveillance data from EU member states. The CDTR's coverage of the cluster ran in parallel with, and sometimes ahead of, WHO's DON bulletins.
