The World Health Organisation is monitoring cases of hepatitis of unknown origin in dozens of children in Britain, some of whom required a liver transplant.
Ten cases of severe acute hepatitis in Scotland were reported to the UN agency on April 5; an additional 64 cases had been found in the UK by April 8, it said on Friday.
Six children needed liver transplants and several patients had to be transferred to paediatric liver units, WHO said.
“Less than five confirmed or possible” cases were reported in Ireland, and three confirmed cases in Spain. No deaths have been recorded.
The infection mainly affected children aged under 10 and symptoms included jaundice, diarrhoea, vomiting and abdominal pain.
The known hepatitis viruses, from A to E, have not been detected in the children, so British health authorities have examined a link to common viruses, or other possible causes, such as Covid-19, infections or environmental factors.
The WHO said the coronavirus that causes Covid-19 and other common viruses had been detected “in several cases”. Their role in the infection’s development was “not yet clear”, it said.
It said it expected more cases to be reported in the coming days.
Experts ruled out any link with Covid vaccines, none of which had been administered to any of the confirmed cases in Britain.
Meera Chand, director of clinical and emerging infections at the UK Health Security Agency, a public health protection body, said “normal hygiene measures” such as handwashing “help to reduce the spread of many of the infections that we are investigating”.
She also called on parents and guardians to be alert to the signs of hepatitis and “to contact a healthcare professional if they are concerned”.
