Since the last update on the African swine fever (ASF) situation issued on February 17, 2026, the Official Veterinary Services (SVO) of the Government of Catalonia have reported the detection of three new outbreaks in wild boars. This brings the total to 33 cases in wild boars found dead, remains found in the wild, or culled because they showed symptoms consistent with ASF in municipalities where cases had already been reported previously. There have been 34 total outbreaks reported to date, 3 of which are primary and 31 secondary, for a total of 195 positive cases in wild boars in 7 municipalities: Cerdanyola del Vallès, Sant Cugat del Vallès, Sant Quirze del Vallès, Terrassa, Rubí, Molins de Rei, and Sant Feliu de Llobregat.

In addition, another 1,433 animals have been tested and found negative, of which 942 were captured or culled without showing clinical symptoms, and 491 were investigated through passive surveillance (whole carcasses or remains found in the wild or animals with symptoms that were culled) in the infected area and its surroundings.
Positive and negative wild boars found per week
A total of 1,042 samples were analyzed by ELISA, of which 6 were positive. All samples that were positive by ELISA were also positive by PCR. No animals were found to be positive by ELISA but negative by PCR. Seventeen animals were also detected as positive by IPT (indirect immunoperoxidase technique), an alternative test for detecting antibodies.

Authorities have determined that the virus spreads at a rate of approximately 1.7 km/month (20.7 km/year).
Regarding the definition of zones, on February 20, the Standing Committee on Plants, Animals, Food, and Feed (PAFF Committee) approved the new regionalization into Zones I and II, which has not yet been published in the OJEU.
Containment measures include the reinforcement of fences with a total of 222 control points where cattle grids and other types of barriers have been installed to prevent wild boars from entering or leaving the area, while allowing vehicles and people to pass through.
