ASF adds 21 new positives in wild boar and reaches 216 cases

Health authorities have confirmed 21 new positive cases of African Swine Fever (ASF) in wild boar, bringing the total number of detected cases to 216 since the outbreak began in November. With this update, the total number of declared outbreaks rises to 37.

Epidemiological situation of African Swine Fever in wild boar

The latest report from the Ministry of Agriculture, Fisheries and Food indicates that the new positives have been detected in municipalities where cases had already been recorded previously, although for the first time an infected wild boar has been confirmed in Sant Just Desvern (Baix Llobregat).

Since the first outbreak was detected on November 28, positive wild boar have been identified in eight municipalities: Cerdanyola del Vallès, Sant Cugat del Vallès, Sant Quirze del Vallès, Terrassa, Rubí, Molins de Rei, Sant Feliu de Llobregat, and Sant Just Desvern.

At the same time, surveillance programs have analyzed 1,708 animals with negative results. Of these, 1,176 correspond to wild boar captured or culled without clinical symptoms, while 532 come from passive surveillance actions, such as the analysis of carcasses or remains found in the natural environment and animals culled for showing signs compatible with the disease in the infected area and its surroundings.

Control strategy against African Swine Fever

Authorities continue to carry out intensive searches for wild boar carcasses, as well as actions aimed at reducing the density of the wild population in the affected area. At the same time, work continues on isolation measures and reinforcement of fencing, prioritizing the control of the usual movement corridors of wild boar, which are being adapted according to the evolution of the epidemiological situation.

Situation on farms

So far, no cases of African Swine Fever have been detected on pig farms. Official Veterinary Services continue to carry out inspections on farms in the area to verify compliance with biosecurity measures and strengthen passive surveillance, with the aim of preventing the virus from entering domestic pig production.
