    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.
