TB disease, on the other hand, means the immune system can no longer keep the bacteria under control. Symptoms can include a bad cough that lasts three weeks or longer; chest pain; coughing up blood or sputum; weakness or fatigue; weight loss; lack of appetite; as well as chills, fever and night sweats, according to the CDC.

People with weakened immune systems -- especially those infected with HIV -- run a higher risk of TB infection than people with normal immune systems.

Currently, there are 10 drugs approved by the U.S. Food and Drug Administration to treat tuberculosis, including the first-line medicines isoniazid, rifampin, ethambutol and pyrazinamide.
