Tuberculosis (or TB) is an infectious diesase that usually attacks the lungs, causing a chronic cough with blood, fever, night sweats, and weight loss. If not treated, tuberculosis kills more than 50 percent of its victims.

The challenge for fighting tuberculosis in poor countries like Haiti is that treatment can be complicated -- it requires multiple antibiotics with long treatment courses. There are also a growing number of multi-drug-resistant strains of the disease creating more treatment problems.
