Tuberculosis (TB) is an infectious disease that typically affects the lungs and is spread from person to person through the air by droplets expelled when coughing or sneezing. This disease poses a global public health threat. In 2016, about 10 million people fell ill with TB and about 1.7 million died worldwide from the disease. Despite efforts to eliminate this disease, TB is now the leading infectious disease killer globally and the leading killer of people living with HIV.
