Overview
If left untreated, group A streptococcal pharyngitis may be self-limiting. In some cases, complications such as peritonsillar abscess, retropharyngeal abscess, mastoiditis, and cervical lymphadenitis may develop in untreated patients.[1][2][3] Less commonly, post-streptococcal glomerulonephritis, rheumatic fever, and toxic shock syndrome may develop as delayed complications. Rarely, vasculitis may occur. The prognosis of strep throat is good with treatment; complications rarely develop with adequate treatment.
Natural history
If left untreated, group A streptococcal pharyngitis may be self-limiting. In some cases, complications such as peritonsillar abscess, retropharyngeal abscess, mastoiditis, and cervical lymphadenitis may develop in untreated patients.[1][2][3] Less commonly, post-streptococcal glomerulonephritis, rheumatic fever, and toxic shock syndrome may develop as delayed complications. Rarely, vasculitis may occur.
Complications
Complications that can develop as a result of strep throat may be divided into suppurative and non-suppurative types:[1][3]
Suppurative
- Peritonsillar abscess
- Retropharyngeal abscess
- Otitis media
- Sinusitis
- Cervical lymphadenitis
- Mastoiditis
- Vasculitis

Prognosis
The prognosis of strep throat is good with treatment. Complications rarely develop with adequate treatment.[1]
