Tuberculosis (TB) has coexisted with humanity since the beginning of human history. In 2022, tuberculosis (TB) was the second leading infectious killer worldwide, following COVID-19, with 1.3 million deaths reported, according to the World Health Organization. Primarily impacting the lungs, TB can cause various symptoms, including coughing, coughing up blood or mucus, chest pain, fever, chills, night sweats, weight loss, and fatigue.
