Epidemiological summary

Since the beginning of 2026 and as at 21 October 2026, one country in Europe has reported locally acquired1 cases of Crimean-Congo haemorrhagic fever (CCHF): Spain (4 cases).

Of the four cases reported in 2026, three were notified in Salamanca, where cases have also been reported in previous years, and one in Ciudad Real, which reported its first locally acquired human case. Hyalomma spp., the main vectors of CCHF virus, are widely distributed across Spain, and the virus is known to circulate in local animal populations. In 2026, no healthcare-associated transmissions were reported, i.e. all individuals were infected through tick bites. The reported dates of symptom onset were between 11 June 2026 and 7 August 2026.

As no new CCHF cases have been reported since week 34, ECDC concludes its weekly update reports for the 2026 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 – are 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 at 21 October 2026.
