Abstract :
An outbreak of African swine fever (ASF) occurred at a farm in central Namibia in March 2018. Fourteen pigs died out of a herd
of 59 animals over a period of 16 days between the rst and sixteenth of March 2018. e clinical signs observed included sternal
recumbency, fever, weakness, pain and reluctance to move, hyperemia of the skin and anorexia, followed by death. Necropsy
ndings included large amounts of unclotted blood in the pleural and peritoneal cavities, diuse carcass congestion, splenomegaly,
consolidation of both lungs, hemorrhagic and frothy airways and trachea, hepatomegaly and congestion, congestion of the gastric
mucosa, enlarged and congested kidneys, ecchymotic epicardial, and endocardial hemorrhages, and very enlarged and congested
urinary bladder. All the remaining pigs were euthanized, burned, and buried under state veterinary supervision. e authors
concluded that the outbreak resulted from indirect transmission of the ASF virus due to lapses in biosecurity measures.
