In a message to parents, Crofton Acamdey headteacher Peter Walker said: "Please be reassured that no one in the school is presenting with any Coronovirus symptoms.

"We are following advice from Public Health England and NHS 111.

"Students who attended the trip are to remain off school for 14 days (calendar days).

"This situation has arisen today given the extension of the exclusion zone in Italy to the whole of Northern Italy. That was not the situation prior to today.

"We have been advised that it is only when symptoms are displayed that others are at risk, and as pointed out above none of those who returned from Italy and who were sent home today have displayed symptoms.

"Any school trip that has been to Northern Italy over half term are in the same situation as ourselves, this is not exclusive to us at Crofton.

"As and when we have any further information/updates we will issue updated communications."
