Tuberculosis (TB) is a major global health issue. According to the World Health Organization (WHO), every year there are worldwide 8.8 million new active TB cases and nearly 2 million TB deaths - 5000 every day - mostly in the poorest communities of the developing world. TB has also become the leading cause of death among people with HIV. While most cases of TB occur in developing countries, it is also reemerging as a threat in major urban populations in Europe, due to global travel.
