The detection of infected wild boars outside the original 'ground zero' in Cerdanyola del Vallès has forced officials to expand the high-risk zone. Areas such as Vallvidrera and Tibidabo in Barcelona are now under surveillance to prevent the virus from reaching major pig farming regions.

Starting this February, citizens are prohibited from entering forests, riverbeds, and rural paths in Sant Feliu de Llobregat. Minister Òscar Ordeig stated that the strategy has shifted to an urgent cull of wild boars within a 20-kilometer radius to safeguard the local economy.

To date, 162 cases have been confirmed across seven municipalities, including Sant Cugat and Terrassa. New perimeter fences are being installed along the AP-7 highway and the Llobregat river to contain the animal movements.
