Study Notes

Tuberculosis (TB)

Tuberculosis (TB) is an infectious lung disease caused by Mycobacterium tuberculosis.
Transmission occurs via airborne droplets. The bacteria are aerosolized, inhaled into the lungs, and adhere to the alveoli.
The body's immune response involves macrophages engulfing the bacteria.
Granulomas (lesions) develop in the lungs as part of the immune response.
Macrophages are immune cells that engulf and destroy pathogens, alerting the immune system to infection.

Symptoms of TB

Persistent cough lasting over three weeks.
Production of purulent or bloody sputum (phlegm).
Unexplained weight loss.
Night sweats.
Lethargy (lack of energy).
These symptoms are screened for on hospital admission to identify potential TB cases and initiate airborne precautions if needed
