*BTV-3/NET2023 variant was isolated from sheep in the Netherlands in September 2023 and genome segments were compared with those of BTV isolates deposited in GenBank. BTV-3, bluetongue virus serotype 3; NS, nonstructural protein; Seg, genome segment; VP, virus protein. †Highest % identity (>97%) compared with BTV-3/NET2023.
