HIV is the name of AIDS pathogen.
Tuberculosis (TB) is caused by an airborne pathogen but is also carried in the saliva. Infected persons can spread the pathogen by breathing, coughing, kissing, or by sharing drinking cups / straws with saliva on them. Infected persons wear a mask until treatment has reduced the number of viruses found (the viral load). A recent case on an overseas flight meant all passengers needed screened for TB and treated on a "just in case" basis because TB is highly contagious!
It is carried in air droplets so enters through the airway and then into the lungs where it thrives on warm, damp environment.
