In September 2018, African swine fever in wild boars was detected in Belgium. We used African swine fever-infected spleen samples to perform a phylogenetic analysis of the virus. The causative strain belongs to genotype II, and its closest relatives are viruses previously isolated in Ukraine, Belarus, Estonia, and European Russia.
