Proposed diagnostic criteria for the individual case definition of PCV‐3‐associated reproductive (A, B, C) and systemic disease (D, E, F). PCV‐3‐reproductive disease: (A) stillborn piglet from a litter with a late reproductive problem characterized by increased percentage of stillborn and weak‐born piglets, (B) mild‐to‐moderate mononuclear inflammatory infiltrates in the arterial wall of the fetal spleen and (C) moderate to high amount of PCV‐3 nucleic acid in the damaged arterial area. PCV‐3‐systemic disease: (D) clinical picture of a pig showing wasting, (E) moderate‐to‐severe non‐suppurative arteritis in the heart and (F) high amount of PCV‐3 genome in the damaged artery
