Tuberculosis (TB) infections are caused by a bacterium called Mycobacterium tuberculosis, and they primarily affect the lungs and respiratory system. Common symptoms include a cough that lasts over three weeks, fevers, chills, night sweats, and rapid weight loss. According to the Centers for Disease Control (CDC), there were approximately 8,300 reported cases of TB in 2022, a slight increase from 2021. Not everyone infected with TB actually becomes sick, but individuals with a latent TB infection (LTBI) can easily spread the infection to others. TB skin tests are required for individuals who work with high-risk populations and are strongly recommended for individuals who have recently returned home from international travel.
