A health trust has started an inquiry after the personal details of 47 Cambridgeshire primary school children were lost.
Cambridgeshire and Peterborough NHS Foundation Trust said paperwork including names, addresses, NHS numbers and dates of birth had gone missing.
The information belonged to reception class pupils at Paston Ridings Primary School, in Peterborough.
It was sent using an “internal post” system, the trust said.
The missing paperwork also contained details of the children’s doctors and school.
Some of the affected 47 pupils could be aged as young as four.
‘Serious incident investigation’
The documents were sent by trust administrators to the School Nursing Service, at Werrington Health Centre, in Peterborough.
A trust spokeswoman said they did not contain any “clinical information”.
“The sheets were being sent as blanks for the school nurse to complete,” she said.
“These blank proformas were sent on 13 January. We were alerted by the school nurse that they had not arrived on 23 January.
“We immediately commenced a serious incident investigation, which is still ongoing.”
The trust said it had attempted to contact the parents of each child.
A school spokeswoman said it was a matter for the trust and did not want to comment further.
