Tuberculosis (TB)
Tuberculosis in the United States
In the United States in 2021, 7,860 new cases (about 2.4 cases per 100,000 people) were reported. However, incidence varies from state to state. For example, in 2020, there were 6.5 cases per 100,000 people in Hawaii and 0.4 cases per 100,000 people in Montana. During 2020, 71% of new cases in the United States occurred in people born outside the United States in areas where tuberculosis is relatively common (such as Africa, Asia, or Latin America). Risk of being infected is increased for people who live in group facilities, such as shelters, long-term care facilities, jails, or prisons, and for those who have been homeless in the past year. In the United States, minorities are disproportionately affected. For example, the number of cases per 100,000 people ranges from 8 times higher in Black people to 33 times higher in Asian people than in White people.
