After 27 years of declining U.S. tuberculosis (TB) case counts, the number of TB cases declined considerably in 2020, coinciding with the COVID-19 pandemic.For this analysis, TB case counts were obtained from the National TB Surveillance System.U.S. Census Bureau population estimates were used to calculate rates overall, by jurisdiction, birth origin, race and ethnicity, and age group.Since 2020, TB case counts and rates have increased each year.During 2023, a total of 9,615 TB cases were provisionally reported by the 50 U.S. states and the District of Columbia (DC), representing an increase of 1,295 cases (16%) as compared with 2022.The rate in 2023 (2.9 per 100,000 persons) also increased compared with that in 2022 (2.5).Forty states and DC reported increases in 2023 in both case counts and rates.National case counts increased among all age groups and among both U.S.-born and non-U.S.-born persons.Although TB incidence in the United States is among the lowest in the world and most U.S. residents are at minimal risk, TB continues to cause substantial global morbidity and mortality.This postpandemic increase in U.S. cases highlights the importance of continuing to engage communities with higher TB rates and their medical providers in TB elimination efforts and strengthening the capacity in public health programs to carry out critical disease control and prevention strategies.
