Abstract
During February-May 2026, Newcastle disease virus subgenotype VII.1.1, related to viruses circulating in Eastern Europe, caused Germany's first major outbreaks in decades, despite mandatory poultry vaccination programs. Clinical signs ranged from inapparent to severe, with low recorded mortality. These findings highlight the need for enhanced surveillance beyond clinical disease detection.
