Hackthorn Church Of England Primary School

A small traditional school with a modern outlook

Infectious & Contagious Diseases

This policy has been agreed by the governing body of the school.

“Children who are unwell with an infectious or contagious disease should not be at school” (Dept. of Health March 1999)

To limit the possibility of an outbreak of infectious disease among other children and staff it is vital parents inform the school if their child contracts a transmittable infection or contagion.

If you are having difficulty deciding whether or not to keep your child off school, some useful advice/guidance is available via the NHS Choices website

A letter must be sent with the child on their return to school explaining their absence.

Headlice: No exclusion or isolation of a child is required. Headlice are a problem not just for schools but the whole community. In accordance with Lincolnshire Health Authority guidance “parents are at the ‘front line’ of head louse detection”. Parents should inspect their children regularly. Leaflets are available from school giving current advice on treatment. Fine tooth combs are also available from school at a cost of £2.50.
