A County Durham nursery which was at the centre of an E.coli outbreak is back open again.
Kirklands Day Nursery in Barnard Castle closed it's doors earlier this month after a number of children tested positive for the bacteria, which causes vomiting and diarrhoea.
Eight youngsters and one adult have been affected.
The latest child to contract the bacteria is not a pupil at the school but they are the sibling of one of the affected pupils.
One child is still seriously ill in hospital but the other eight positive cases are recovering at home.
The nursery's had a deep clean and pupils and staff who've had two negative tests can go back in.
Investigators at Public Health England (PHE) and Durham County Council are still trying to locate the source of the infection at the nursery on Bede Road.
Dr Peter Acheson, a consultant at PHE's North-East centre, said: "It has not yet been possible to identify a definite source.
"The nursery has now undergone a thorough deep clean and environmental samples taken inside the nursery have not shown any traces of E.coli.
"For these reasons we have advised that the nursery can now re-open but only to staff and children who have had two negative test results.
"This is to prevent the infection being re-introduced into the nursery."
He added: "Testing of all children and staff is progressing well but will take time to complete due to the need for each person to be tested twice.
"We are continuing to investigate the outbreak but often in situations of this kind it is not always possible to identify a definitive source of the original infection.
"The most important action is to make sure control measures are in place to prevent further spread."
