- Flushed face with circumoral pallor
- White strawberry tongue early in disease gives way to beefy red strawberry tongue later
- May have petechiae starting 1 to 3 days after the rash, forming in the skin creases along Pastia lines
Management
- Treated with a 10-day course of penicillin (or clindamycin, if penicillin-allergy)
