Scarlet fever

Last edited: 4/15/2026

Overview

Scarlet fever is characterized by a distinctive rash accompanying sore throat and flushed cheeks, primarily affecting children 1. Historically severe, it now rarely poses life-threatening risks 1.

Diagnosis

  • Clinical Presentation: Sore throat, fever (>38°C in 73%), rash, flushed cheeks, enlarged lymph nodes (70%), absence of cough (73%) 2.
  • Microbiological Confirmation: Rapid antigen-detection test or throat culture 2.
  • Centor Score: Often ≤2 points in confirmed cases, indicating low likelihood of streptococcal complications 2.
  • Management

  • Antibiotics: Penicillin V or amoxicillin as first-line treatment (specific doses not provided in abstracts) 1.
  • Supportive Care: Symptomatic treatment including hydration and fever management 1.
  • Special Populations

  • Pediatrics: Majority of cases occur in children under 4 years old, with distinct clinical features differing from typical streptococcal pharyngotonsillitis 2.
  • Comorbidities: Rare cases may present with hepatitis, hematuria, and elevated liver enzymes, particularly noted in young children 3.
  • Key Recommendations

  • Diagnose and treat scarlet fever promptly with antibiotics to prevent complications (Evidence: Moderate 21).
  • Consider atypical presentations in pediatric patients, especially in young children (Evidence: Moderate 2).
  • Monitor for rare complications such as hepatitis and hematuria, particularly in pediatric cases (Evidence: Weak 3).
