Late complications of group A streptococcal infection include rheumatic fever and poststreptococcal glomerulonephritis. Risk of acute rheumatic fever following an untreated streptococcal infection has been estimated at 3% in epidemic situations and approximately 0.3% in endemic scenarios. If a nephritogenic strain of group A beta-hemolytic streptococci causes infection, the individual has a 10-15% chance of developing glomerulonephritis.
