The Centers for Disease Control and Prevention says the number of U.S. tuberculosis cases in 2023 was at the highest level since 2013 and rose among all ages.
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.
The number of tuberculosis cases in 2023 rose by 15% in California compared to the previous year. That's the highest year-over-year increase in 35 years.
