My Mom had scarlet fever as a kid.Beta hemolytic strep is nasty stuff. Important thing is to get to a doc if you think you have strep throat, get tested, get on antibiotics and make sure you take the whole prescription.
I did both times but it didn't stop me from getting rheumatic fever. You can also have problems if you get scarlet fever. Afterwards I found out that most of the females on my mother's side of the family had either Strep Throat or Scarlet Fever. A good number had rheumatic fever also.
Gee mom, thanks for the great genes....
