Study Notes

Overview of Pneumonia

Pneumonia is a serious lung infection characterized by inflammation of the alveoli, small air sacs in the lungs.
Infected alveoli can fill with fluid or pus, leading to breathing difficulties.
The severity of pneumonia varies from mild discomfort to severe, life-threatening conditions, particularly affecting vulnerable groups like the elderly, young children, and immunocompromised individuals.

Causes of Pneumonia

Bacterial Causes:
- Common bacteria include:
  - Streptococcus pneumoniae
  - Haemophilus influenzae
  - Staphylococcus aureus
Viral Causes:
- Viruses such as:
  - Influenza
  - Respiratory syncytial virus (RSV)
  - Coronaviruses can lead to pneumonia.
Fungal Causes:
- Fungal infections that cause pneumonia include:
  - Histoplasmosis
  - Coccidioidomycosis
  - Cryptococcus
- Fungal pneumonia is more common in individuals with weakened immune systems.
Parasitic Causes:
- Less frequently, parasites can initiate pneumonia, including:
  - Toxoplasma gondii
  - Strongyloides stercoralis
  - Ascaris lumbricoides
  - Schistosoma species

Symptoms of Pneumonia

Persistent Cough: Often results in phlegm or pus production.
Fever and Chills: Characterized by elevated body temperature and shaking chills, indicating infection.
Difficulty Breathing: May present as shortness of breath or rapid, shallow breathing.
Chest Pain: Discomfort is common, especially during coughing or deep breaths.
Fatigue: Individuals may experience unusual tiredness or weakness.
Nausea or Vomiting: Symptoms can sometimes be accompanied by diarrhea.
