Surveillance data shows 77 percent of reported patients were hospitalized, while 57 percent exhibited neurological symptoms. Additionally, 130 deaths have been recorded across 13 countries as of October 14, 2026.
The players
European Centre for Disease Prevention and Control
This is an agency of the European Union aimed at strengthening Europe's defenses against infectious diseases.
The details
Transmission occurred in 222 European regions, with Belgium reporting locally acquired human infections for the first time this year. Italy recorded the highest burden with 764 cases, followed by Greece with 455, France with 159, Spain with 141, and Romania with 121 cases.
Timeline
22 May 2026 marks the earliest symptom onset recorded in Italy.
30 September 2026 marks the latest symptom onset recorded in Italy.
7 October 2026 served as the data cutoff for the monthly report.
14 October 2026 served as the data cutoff for the weekly report.
Health Landscape
This reporting follows the disease monitoring protocols established by the European Centre for Disease Prevention and Control. Such surveillance is critical for managing seasonal vector-borne diseases and protecting public health across the continent.
Travelers and residents in affected regions should be aware that blood donors from high-risk areas are subject to a 28-day deferral period. Since many infected individuals remain asymptomatic, these measures are essential to ensure the safety of the blood supply.
The takeaway
While the majority of patients recover, the high hospitalization rate necessitates vigilance regarding mosquito exposure in active regions. Individuals should monitor local health advisories for updates on regional transmission activity.
