Tuberculosis

• Tuberculosis cases in the U.S. rose to over 10,600 in 2024, marking the third consecutive annual increase and the highest total since 2013, at about 3 per 100,000 people. • Health experts attribute the rebound to pandemic-related underdiagnosis, untreated latent infections, and increased international travel from high-prevalence areas. • Local public health TB programs remain understaffed, straining response capacity amid the uptick.

• UC Davis researchers created a new blood test to quickly detect the active, infectious form of tuberculosis, aiming to accelerate diagnosis and curb spread. • TB killed 1.23 million globally in 2024, with over 10,000 U.S. cases including 2,000 in California; the test targets high-burden areas like India. • Professor Imran H. Khan submitted trial data to India's ICMR for approval and co-founded AppGenex Diagnostics to commercialize it.
