Although strep throat itself isn't dangerous, it may lead to serious complications — sometimes even with treatment.
Spread of infection
Strep bacteria may spread, causing infection in your:
- Middle ear
Strep infection may lead to other inflammatory illnesses, including:
- Scarlet fever, an illness characterized by a rash
- Inflammation of the kidney (poststreptococcal glomerulonephritis)
- Rheumatic fever, a serious condition that can affect the heart, joints, nervous system and skin
Researchers are investigating a possible link between strep infection and a rare condition called Pediatric autoimmune neuropsychiatric disorder associated with group A streptococci (PANDAS). PANDAS is a term used to describe certain children whose symptoms of neuropsychiatric conditions, such as obsessive compulsive disorder or tic disorders, are exacerbated by strep infection.
