ABSTRACT: Tuberculosis (TB) is an airborne infectious disease caused by Mycobacterium tuberculosis, which is spread by infected patients. Upon infection, some individuals develop active TB, whereas others remain in a state of latent TB infection (LTBI), in which the bacterium resides without symptoms or transmission, potentially progressing to active TB. The prompt diagnosis and treatment of LTBI are crucial for effective TB management. When TB cases occur, rapid epidemiological investigations are conducted to identify contacts in households and congregate facilities, followed by testing for TB and LTBI. In 2023, 107,804 contacts were investigated across 17,663 households and 3,620 facilities, and 200 additional TB cases (185.5 per 100,000 contacts) were detected. Among household conta
