Epidemiological summary

Since the beginning of 2025 and as of 8 October 2025, two countries in Europe have reported cases of Crimean-Congo haemorrhagic fever (CCHF): Spain (three) and Greece (two). This week, no new cases of CCHF have been reported to ECDC.

The CCHF cases that occurred in June in Greece’s Thessaly region are unusual, as the area previously had no reported cases or known virus circulation. The primary patient was likely infected by a tick bite, while the secondary case involved a healthcare worker. These are the first cases since 2008, when a single local case was identified in Thrace. In contrast, CCHF cases in Spain are expected due to known virus presence among animals and prior human cases in Salamanca, Castile and León, Toledo, and Castilla-La Mancha.

As no new CCHF cases have been reported since week 32, ECDC concludes its weekly update reports for the 2025 season. However, the report will be updated on an ad hoc basis if new cases are reported to ECDC.

Introduction

CCHF is a tick-borne viral disease that is emerging in Europe, with locally acquired cases reported in several EU/EEA countries. In the light of this development, the European Centre for Disease Prevention and Control has implemented seasonal enhanced surveillance to monitor the occurrence of cases in the EU/EEA. The primary objective is to inform public health authorities and support the implementation of appropriate response measures.
CCHF is a notifiable disease at the EU level and cases are reported in accordance with the EU case definition. The table and map in this report show the countries and areas where CCHF cases – and their corresponding case numbers – have been reported to the European surveillance portal for infectious diseases (EpiPulse Cases).
Please note that cases acquired in Portuguese and Spanish Outermost Regions are included. However, due to the distinct epidemiological situation and differences in surveillance systems, cases acquired in the French Outermost Regions are not included.
Here we present the report as of 8 October 2025.
