Tuberculosis (TB) is an infectious
disease that primarily affects the lungs, and the number of cases of TB is on
the rise. Many people think of TB as a rare disease that only affects people in
undeveloped countries, but that is not the case any more. Since the 1980s, the
number of cases of TB has risen dramatically due to the spread of HIV, which is
the virus that causes AIDS.
