In 2011, nearly 9 million people around the world became sick with tuberculosis, and there were 1.4 million TB-related deaths, Reuters
reports. The disease requires six to nine months of treatment.

Sirturo, however, does not come without serious risks. The FDA warned that Sirturo may potentially cause heart attacks heart problems and "should be prescribed carefully by doctors."
