US tuberculosis cases were at their the highest level in a decade in 2023
The number of U.S. tuberculosis cases in 2023 were the highest in a decade, according to a new government report. Most U.S. TB cases are diagnosed in people born in other countries. Experts say the 2023 number is in part a combination of a surge in TB cases internationally — the World Health Organization said TB was behind only COVID-19 in infectious fatal diseases worldwide in 2022.
