What Makes the Fight Against African Swine Fever a Test of Patience - Germany's swine fever crisis deepens as virus spreads to Sauerland region

African swine fever (ASF) has struck again in Germany, this time hitting the Sauerland region hard. The virus, which is almost always deadly for pigs, has forced authorities to seal off a 15,500-hectare zone with over 120 kilometres of fencing. Despite efforts, the disease continues to spread across multiple states, causing disruptions for farmers, hunters, and even tourists.

ASF first appeared in Germany in September 2020, when cases were confirmed in Brandenburg. Since then, the virus has spread to six federal states: Brandenburg, Mecklenburg-Vorpommern, Sachsen, Hessen, Rheinland-Pfalz, and Baden-Württemberg. Among these, Hessen, Rheinland-Pfalz, and Baden-Württemberg remain the worst affected, with ongoing infections in both wild and domestic pigs. Nordrhein-Westfalen has also seen a recent surge, with around 320 infected wild boars detected.

Containing the outbreak is proving difficult. The Sauerland region's rugged terrain, thick forests, and large wild boar population make it hard to track and control the disease. Hunters and search teams with dogs now patrol inside and outside the fenced zone, checking for signs of further spread. Authorities are culling infected animals, reducing wild boar numbers, and removing carcasses quickly to stop the virus from spreading.

Farms inside the outbreak zone face restricted market access, while those outside must follow strict biosecurity rules. Winter conditions, such as snow and frozen ground, could slow down control efforts even more. Some major events have been cancelled, and a popular tourist site has closed, though overall visitor numbers have not dropped sharply.

Experts warn that eradicating ASF is a long-term battle. Full elimination typically takes at least two years, with steady efforts needed to keep the disease in check.

The current outbreak remains confined to a fenced core zone, but the virus persists across several German states. Farmers, hunters, and local authorities continue working to limit its impact. Until the disease is fully under control, restrictions and monitoring will stay in place.
