West Nile Virus Hits Record Season, Spreads North into Netherlands and Belgium

The European Centre for Disease Prevention and Control (ECDC) has warned that this year marks the worst West Nile virus season ever recorded in the EU, with the infection moving further north than before.

Dozens of human cases have now been confirmed in the Netherlands and Belgium, making these the most northerly hotspots for the disease in Europe to date.

While the virus is traditionally a southern‑European concern, health officials say the northward shift underscores changing climate patterns and the need for heightened surveillance across the continent.

In Brussels, the capital of EU politics, the news has sparked a mix of concern and dry humour – some locals joke that even the city’s famed cafés might soon need mosquito‑proof lids.

Public‑health authorities in both Belgium and the Netherlands are ramping up monitoring and preventive measures, urging residents to protect themselves from mosquito bites and to stay alert for any symptoms.

The ECDC’s alert serves as a reminder that West Nile virus is no longer confined to the Mediterranean fringe and that European cities, even those far from the traditional warm zones, must be prepared for its spread.
