Diagnostic Considerations

Streptococcal pharyngitis is most commonly caused by group A streptococci (45%) and anaerobes (18%), which often occur as a co-infection.

Much of the concern about diagnosing streptococcal pharyngitis is related to the complications of infection, particularly acute rheumatic fever and poststreptococcal glomerulonephritis as a late complication. Therefore, maintaining a high level of suspicion for streptococci group A in the presence of pharyngitis is advisable.

Other medical issues/problems to consider include the following:

  • Exercise-induced asthma

  • Bacterial tracheitis

  • Cough

  • Cystic fibrosis

  • Influenza

  • Hyperreactive airway disease

  • Retained foreign body

  • Tonsillitis

  • Occupational exposures
