Thereafter the planning was straightforward and based around the ‘bubble system’ a term developed in UK Boarding schools in the last year. The ‘bubble’ is a core group of pupils (usually the same class) who live in a self-contained group that sleeps, eats, and studies together, and doesn’t mix with any other group. Everyone in the group has a daily medical check-up with one of the infirmary staff. Inevitably they must have interaction with others from outside the ‘bubble’, but this is done using normal covid protocols including mask wearing and social distancing. In the worst-case scenario, where a child becomes covid positive, the ‘bubble’ can be isolated and appropriate steps taken to treat the unwell and quarantine the others without the rest of the school necessarily stopping.
