1Excludes 47 cases of disease caused by bacillus Calmette-Guérin M. bovis. M. bovis cases from 2004 to 2017 were defined predominantly by spoligotyping results or by microbiologic expertise. M. bovis cases from 2018 to 2024 were defined using a whole genome sequencing-based lineage.
2Persons born in the United States, certain U.S. territories, or elsewhere to at least one U.S. citizen parent are categorized as U.S.-born. All other persons are categorized as non-U.S.–born.
3Includes all genotyped M. bovis cases, including cases in persons for whom origin of birth is unknown.
4Percentages calculated based on all M. bovis cases.
