Pneumococcus: Or something else? Differential Diagnosis

There are numerous infectious diseases that can be caused by pneumococcus. Chief among these are:

Respiratory system (J00-J99)

• Pneumonia (pneumonia)
• Rhinosinusitis – inflammation of the nose and sinuses.
• Sinusitis (inflammation of the paranasal sinuses).
• Tracheobronchitis – inflammation of the trachea and bronchi.

Eyes and eye appendages (H00-H59).

• Ulcer serpens corneae (corneal ulcer).

Cardiovascular system (I00-I99)

• Endocarditis (inflammation of the inner wall of the heart).
• Pericarditis (inflammation of the pericardium)

Mouth, esophagus (esophagus), stomach, and intestines (K00-K67; K90-K93).

• Appendicitis (“appendicitis”).
• Peritonitis (“inflammation of the peritoneum”)

Ears – mastoid process (H60-H95)

• Mastoiditis (mastoid process inflammation).
• Otitis media (inflammation of the middle ear)

Psyche – nervous system (F00-F99; G00-G99)

• Brain abscess – encapsulated collection of pus in the area of the brain.
• Meningitis (meningitis)

Genitourinary system (kidneys, urinary tract – reproductive organs) (N00-N99).

• Endometritis (inflammation of the uterus).

Differentially, other bacterial and viral infections may also be considered:

• Bacterial pathogens
  • Chlamydia
  • Haemophilus influenzae
  • Moraxella catarrhalis
  • Mycoplasma
• Viral pathogens
  • Adenoviruses
  • Human coronaviruses (OC43, 229E)
  • Influenza viruses
  • Paramyxoviruses (i. W. RS virus)
  • Picornaviruses (esp. rhinoviruses).
