West Nile virus infections are spread across 16 European countries, not one uniform risk

ECDC reports 1,569 locally acquired human West Nile virus infections in 186 affected areas across 16 European countries as of September 23, 2026. Six areas were reported as first affected in the latest week. This is a distributed seasonal pattern, not a uniform risk across Europe. No single map point is shown, because a pin would imply an epicentre the surveillance does not support.

Corrections & updates

This record is reverified against its primary sources on a twice-daily scan. When the evidence changes, the record changes and the change is logged in the review record — including signals we remove. This is situational awareness, not clinical or travel advice.
