Two of the four children being treated following an E.coli outbreak in Fife are to be released from hospital, doctors have confirmed.
A total of 13 cases were linked to the Dunfermline outbreak
The remaining pair at the Royal Hospital for Sick Children in Glasgow are "stable with signs of improvement".
The four, who all attend the Careshare Nursery in Dunfermline, have been receiving treatment for kidney failure - haemolytic uraemic syndrome.
The total number of cases connected with the outbreak has remained at 13.
Investigations into the source of the outbreak, which was first reported on 9 May, are continuing.
The nursery at Lauder College looks after about 100 children.
Dr Neil Hamlet, of NHS Fife, said a total of 141 adults and children have now received official "clearance from infection" letters.
He said: "This permits them to return to their workplace or nursery.
"These adults and children pose no identifiable risk in relation to E.coli O157 transmission.
"Nursery managers have been made aware of the requirement of this clearance letter prior to re-admission to Careshare Lauder Nursery children."
Dr Hamlet added: "Preventing spread of E.coli O157 infection between people depends on effective hand washing after using the toilet, before and after handling food, and before eating.
"This needs to be supervised for younger children."
The incident control team involving NHS Fife, Health Protection Scotland, Fife Council, the Care Commission and others will continue to meet during the coming week.
