School exclusion advice for rashes
Overview
Rashes from common childhood infections frequently raise questions about school or childcare exclusion. Exclusion guidance is a public‑health measure to limit transmission in congregate settings and should be given using nationally accepted wording.

- The purpose of exclusion is to reduce onward transmission by keeping infectious individuals away during the period they are most likely to infect others; exclusion periods are attendance recommendations and do not replace clinical assessment of fitness for school.
- A child may meet exclusion criteria yet be too unwell to attend, or may be clinically well but still within the exclusion window and therefore must not attend.
- Always follow local Health Protection Team (HPT) or public‑health advice if it differs from general guidance.
Clinical flags (brief, exam-relevant)
- Chickenpox: Prodromal fever followed by a pruritic vesicular rash in successive crops; infectious from approximately 1-2 days before the rash until lesions crust. Complications include secondary bacterial infection and pneumonia in high‑risk groups. Pregnant contacts need rapid assessment.
- Measles: Fever, cough, coryza, conjunctivitis and...
