    1. Worldwide, 2-3 million people each year die of TB. Annually, eight million people develop active TB disease. Between 1993 and 1996, there was a 13% increase in TB cases worldwide. Nearly 2 million TB cases per year occur in sub-Saharan Africa, about 3 million per year in south-east Asia, and about a quarter of a million TB cases per year occur in Eastern Europe.
