- Tuberculosis
- Causes
- Mycobacterium tuberculosis/ Mysobacterium bovis
- Infected droplets of mucus e.g. coughing, spitting, sneezing
- High populations, people who work near cows, children, elderly and malnourished /immunodeficiency at risk
- Destroys lung tissue and weakens immune system
- Pulmonary or Extrapulmopnary
- Symptoms
- Cough with bloody sputum - evidence of damage to lungs
- Fatigue or shortness of breath (KILLS) due to lung tissue damage. Reduces efficiency of oxygenating blood
- High temp / feeling ill: non specific response fever slows down bacteria but reduces body functions
- Weight loss / no appetite (KILLS) mechanisms that control hunger not prioritised, trying to fight infection
- Night sweats due to fever
- Treatment
- It kills you because vital organs break down due to insufficient supply of oxygen due to damaged lungs
- Also secondary infections due to weakened immune system
- X-rays/body samples diagnose it
- BCG vaccine for those at risk but limited for fear of resistance
- Multiple antibiotics for up to 18 month.
- Better health, lifestyle, working conditions to prevent development/ spread
- It kills you because vital organs break down due to insufficient supply of oxygen due to damaged lungs
- How it reacts with the immune system
- When exposed you either kill bacteria, fail to kill it but contain it in a tubercle (latent) or it spreads (active)
- Latent TB is primary infection. Tubercle with macrophages may not kill all which grow and become active when you are malnourished
