ASF Spain: Virus spreads to 8th municipality
The number of infected wild boar found with African Swine Fever (ASF) north of Barcelona, Spain, has grown further to 216 – a growth of 21 new cases. One of them was found in the nearby municipality Sant Just Desvern, which hadn’t reported any infected wild boar before.
With detailed data from the Spanish Ministry of Agriculture, Fisheries and Food (MAPA) it is possible to more exactly calculate the size of the infected areas. This measures 16.8 km north to south, and 7.5 km east to west.
In total, 2 districts (comarcas) have been hit with ASF virus, i.e. Vallès Occidental (202) and Baix Llobregat (14). At the level of municipalities, 8 have found the virus in its wild boar population, 5 of them in Vallès Occidental district and 3 in Baix Llobregat district. The municipality with most outbreaks is Cerdanyola del Vallès with 129 infected carcasses, see Table 1.
The detailed MAPA information, with information on the location on each infected animal, can be found back in the map below.
Simplified version of MAPA data
The data submitted to the World Organisation for Animal Health (WOAH) show a simplified version of the MAPA data. Those data revolve around “foci,” or primary outbreak locations – clustering secondary outbreaks within the first. That is why in WOAH data, in total 37 outbreak locations have been communicated for in total 216 carcasses.
On the basis of WOAH chronological data, it is possible to see a slightly rising trend as to how many wild boar have been found every month. In November 2025, 13 infected wild boar were found north of Barcelona, which went up via 34 (December) and 78 (January) to 91 (February), see Figure 1.
High-risk area expanded
As a consequence of the latest findings, the municipality Sant Just Desvern, as well as its neighbouring municipality Esplugues de Llobregat, have been added to the high-risk areas now. In those areas, there is a ban on accessing natural areas and engaging in individual or group activities. Access to homes and sports facilities within the perimeter and economic activities in enclosed spaces are permitted.
