Directly from USDA website: At least 26 serotypes of BTV (genus Orbivirus in the family Reoviridae) have been identified worldwide. The status of bluetongue serotypes in the United States as of 2022 follows: • Established: (Serotypes 3, 6, 10, 11, 12, 13, 17) a specific serotype has been reported annually for two consecutive years in a geographic region where vector incursions due to weather events would not be expected; OR there is documented phylogenetic evidence of virus reassortment with previously established strains in domestic and wild animals. • Reported: (Serotypes 1, 2, 5, 9, 14, 15, 18, 19, 22, 24) a detection based on the current APHIS BTV serotype case definitions that has not been detected in the past five years; OR detection in geographic regions where vector incursions due to weather events are expected and have not been detected consecutively for two years. • Not reported: (Serotypes 4, 7, 8, 16, 20, 21, 23, 25, 26) (USDA)
