tuberculosis, which is a very common, highly infectious disease of (primarily) the lungs. It is usually spread via saliva when those with the active form of TB sneeze or cough. Healthy people who contract the disease normally carry an asymptomatic, latent form (LTBI) and have a 10% chance of developing an active form of the disease sometime later in life if their immune system becomes weakened.
Smokers and patients with AIDS are at higher risk of developing the active form.
