Transmission
M. Tuberculosis particles becomes airborne when an actively infected person speaks, coughs, laughs, sneezes, or expels fluid from their lungs. Once airborne the tiny particle droplets containing the microorganism M. Tuberculosis are inhaled by new host who will then become infected. TB does not discriminate as people of all ages are at risk of infection. There are two stages to infection, latent and active. Latent TB affects one third of the worlds population. In latent stage a person is not ill or showing any symptoms, but have been infected by the bacteria. Those who are in latent stage of TB, have a 10% chance of it becoming active. Those with weakened immune systems are at an increased risk of becoming active. Once TB becomes active, symptoms will begin to appear.
