The numbers should speak for themselves. In 2006, there were 9.2 million new tuberculosis (TB) cases and 1.7 million TB deaths. Of these cases, 5.3% were a tough strain of TB that is resistant to treatment (known as MDR-TB, or multiple drug resistant tuberculosis). The total cost of TB control programs in high burden countries is estimated to be about $2.3 billion in 2008.
