While latent TB is symptomless, the symptoms of active TB include the following:

· Coughing, sometimes with mucus or blood

· Chills

· Fatigue

· Fever

· Loss of weight

· Loss of appetite

· Night sweats

Tuberculosis usually affects the lungs, but can also affect other parts of the body. When TB occurs outside of the lungs, the symptoms vary accordingly. Without treatment, TB can spread to other parts of the body through the bloodstream:

· TB infecting the bones can lead to spinal pain and joint destruction

· TB infecting the brain can cause meningitis

· TB infecting the liver and kidneys can impair their waste filtration functions and lead to blood in the urine

· TB infecting the heart can impair the heart's ability to pump blood, resulting in a condition called cardiac tamponade that can be fatal
