the UK Health protection Agency have produced a practical guide for staff on managing cases of infectious diseases in children and young people settings, including education.
Within the tools and resources, there is an exclusion table with guidance to indicate the time period an individual should not attend a setting to reduce the risk of transmission during the infectious stage.
This guidance is not intended to be used as a tool for the diagnosis of infections. The information is designed for use by staff members in children and young people settings (for example teachers, managers, teaching assistants, and cleaners) to prevent and respond to infection, incidents and outbreaks.
You can find the guidance here.
