In brief: Up to 50%

The rate of development of rheumatic fever in individuals with untreated strep infection is estimated to be 3%.
The incidence of recurrence with a subsequent untreated infection is substantially greater (about 50%).[16] the rate of development is far lower in individuals who have received antibiotic treatment. Persons who have suffered a case of rheumatic fever have a tendency to develop flare-ups.
