The following conditions may indicate strep throat infection:
- Appendicitis (inflammation of the appendix).
- Endocarditis (meningitis of the heart)
- Erysipelas* (erysipelas) – purulent infection of the skin and subcutaneous tissue (subcutis), which in the predominant case is caused by ß-hemolytic group A streptococci (GAS (group A streptococci); Streptococcus pyogenes).
- Urinary tract infections
- Impetigo contagiosa* (contagious borky lichen) – common, highly contagious, superficial infection of the skin that occurs primarily in childhood; typically in infancy and early childhood; clinical presentation: honey-colored crusts on the face and hairy head area; streptococci or staphylococci (smear).
- Necrotizing fasciitis* (“flesh eating disease”) – foudroyant proceeding, bacterial soft tissue infection of the skin and subcutis.
- Neonatal sepsis – blood poisoning of the newborn child.
- Neonatal meningitis (meningitis).
- Otitis media* (inflammation of the middle ear)
- Peritonitis (peritonitis)
- Pharyngitis* – inflammation of the pharyngeal mucosa.
- Phlegmon – diffuse inflammation of the connective tissue, which continues to spread under the skin.
- Pneumonia (pneumonia)
- Puerpural sepsis – sepsis (blood poisoning), which used to occur frequently after childbirth due to poor sanitary conditions.
- Scarlatina* (scarlet fever)
- Sepsis (blood poisoning)
- Streptococcal toxic shock syndrome (STSS) – rapidly progressive fasciitis (foudroyant life-threatening infection of the skin, subcutis (subcutaneous tissue), and fascia with progressive gangrene; often involves patients with diabetes mellitus or other conditions that lead to circulatory disturbances or decreased immune defenses), which can lead to shock
- Tonsillitis* (tonsillitis).
- Ulcus serpens corneae (“creeping ulcer“) – ulcer (ulcer) of the cornea (cornea of the eye), which is caused by penetration of the pathogen into the superficial cornea and a rapid “creeping” spread is possible.
- Wound infections
- Scarlet fever – wound infection with the scarlet fever pathogen.
- Dental caries
* GAS (Group A Streptococcus).
