The number of children with hepatitis has now risen to 108 across the UK, with eight children - including at least one in Scotland, having received a liver transplant as a result of having contracted the condition.
Meanwhile, The World Health Organisation has confirmed that 14 cases of the virus had been reported across Scotland's central belt.
The Royal Hospital for Children in Glasgow saw the number of kids who presented with abnormal liver function in March exceed the annual total expected for the whole of Scotland.

On Tuesday, Scotland’s public health minister Maree Todd said the mysterious strain of hepatitis had no link to the Covid-19 vaccine, as none of those identified with hepatitis had had the jag.
With concerns that coronavirus could be a cause of the spike in hepatitis cases, an investigation of global importance has been launched.
Dr Meera Chand, director of clinical and emerging infections at UK Health Security Agency (UKSA), said: "We are working with the NHS and public health colleagues in Scotland, Wales and Northern Ireland to swiftly investigate a wide range of possible factors which may be causing children to be admitted to hospital with liver inflammation known as hepatitis.
"Information gathered through our investigations increasingly suggests that this is linked to adenovirus infection. However, we are thoroughly investigating other potential causes."
Adenovirus is a family of common viruses that usually cause a range of mild illnesses and most people recover without complications.
She continued: “Normal hygiene measures such as thorough hand washing (including supervising children) and good thorough respiratory hygiene, help to reduce the spread of many common infections, including adenovirus.
“We are also calling on parents and guardians, to be alert to the signs of hepatitis (including jaundice) and to contact a healthcare professional if they are concerned.”
