-
Types:
- Community-acquired pneumonia (CAP)
- Hospital-acquired pneumonia (Nosocomial pneumonia)
- ICU-acquired pneumonia
- Non ventilated intensive care acquired pneumonia (NV-ICUAP)
- Ventilator associated pneumonia (VAP)
- Typical pneumonia
- Atypical pneumonia
- Lobar pneumonia
- Bronchopneumonia
- Interstitial pneumonia
- Causes (bacteria): Streptococcus pneumoniae, Mycoplasma pneumoniae, Legionella pneumophila, Chlamydia pneumoniae, Haemophilus influenzae, Staphylococcus aureus, etc.
- Causes (viruses): Influenza, parainfluenza, Measles, Herpes simplex, Varicella.
- Causes (risk factors): Alcoholism, COPD and/or smoking, Nursing home residency, Poor dental hygiene, exposure to bats or soil enriched with bird droppings, Exposure to birds, Exposure to rabbits.

- Epidemiology: 4th leading cause of death globally, 2-3 million cases/year, 60,000+ deaths/year (2014 US data).

- Diagnosis investigations: Blood tests (CBC, serum creatinine, electrolytes, CRP, ESR ), sputum samples (Gram stain, culture, NAAT), chest X-ray
- Treatment: Empirical therapy; consider outpatient or inpatient treatment based on severity, comorbid conditions, age, and symptoms.. Specific antibiotic treatments are given based on the likely pathogen (e.g., Strep. pneumoniae, Mycoplasma).
- Complications: Septicemia, Lung abcess, Para-pneumonic effusions, Hypotension, Empyema, Respiratory failure/renal failure.
- Differential Diagnosis: Pulmonary infarction, Pulmonary/pleural tuberculosis, Pulmonary oedema, Pulmonary eosinophilia, Malignancy (bronchoalveolar cell carcinoma), Cryptogenic organising pneumonia, etc
- Risk factors: Age (<16 or >65), co-morbidities (HIV, diabetes, chronic kidney disease, malnutrition ), viral infections, other respiratory conditions (cystic fibrosis, bronchiectasis), lifestyle (smoking, excess alcohol, IV drug use), latrogenic factors (immunosuppressants)
