Europe West Nile Season Reaches 1,569 Local Cases in 16 Countries
- As of 23 September 2026 ECDC counted 1,569 locally acquired human West Nile virus infections in 16 European countries this transmission season.[1][2]
- Italy leads with 696 cases, then Greece 355, Spain 125, France 102 and Romania 91, with smaller numbers in North Macedonia, Serbia, the Netherlands, Croatia, Belgium and Austria (7 cases) and Germany (4).[2]
- The season has grown fast: by 5 August ECDC had 139 Italian and 65 Greek cases, and by early September Italy had 516 and Greece 284.[3]
- Severity is high among reported cases: in early August, 72% of cases were hospitalized and 58% had neurological symptoms, and 12 deaths had been reported across Greece, Italy and Romania.[3]
- Germany's cases appeared in Berlin, Leipzig and Rhineland-Palatinate, well north of the Mediterranean countries that dominate the count.[2]
- The virus circulates between wild birds and mosquitoes, which pass it to people; most infections cause no symptoms and ECDC counts only infections acquired in the reporting country, so travel cases are excluded.[2]

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
