Another 25 British children have fallen ill with hepatitis of unknown origin while the mysterious outbreak continues.
Health officials announced the new cases today, bringing the UK’s cumulative total to 222 since the first was detected in January.
Of the confirmed patients, 158 were in England, 31 in Scotland, 17 in Wales and 16 in Northern Ireland.
They are found predominantly in children under the age of five, but a small number of children over the age of 10 have also been shot.
Scientists are still baffled by what is causing life-threatening liver disease, with a weakened immunity to the common cold due to blockages that are still believed to be one of the main culprits.
The complication has been detected in hundreds of children in Europe, the United States, South America, the Middle East and Asia. At least 12 young people have died and dozens have needed liver transplants. No children have died in the UK.
The UK Health Security Agency (UKHSA) said it was still investigating to find out what was behind the mysterious outbreak, with the usual hepatitis A, B, C, D and E viruses excluded from the results. laboratory tests.

The main theory is that the wave of hepatitis cases is being triggered by a group of viruses that usually cause the common cold, known as adenovirus.
Scientists are investigating whether a mutated strain of adenovirus has evolved to become more severe or whether the lack of social mix during the pandemic weakened children’s immunity.
Nor have they been able to rule out an old Covid infection.
UKHSA officials said there was no evidence linking the outbreak to the Covid vaccine, as most cases had been in children under the age of five, who had not been punctured.
New cases appear to be slowing, with 25 registered in the nine days to May 25 down 26 percent from the 34 registered in the six days to 16 May.
Dr Tassos Grammatikopoulos, a consultant at King’s College Hospital in London who has treated some of the sick children, said last week that the UK “appears to have overcome the peak” of the outbreak.
Dr Renu Bindra, senior medical advisor at UKHSA, said: “Our research continues to suggest an association with adenovirus and we are exploring this link, along with other possible contributing factors, such as previous infections such as Covid.
“We are working with other countries that are also looking at new cases to share information and learn more about these infections.”
He added: “The chances of children developing hepatitis are still extremely low.
“Maintaining normal hygiene measures, including making sure children wash their hands properly regularly, helps reduce the spread of many common infections, including adenovirus.
“We continue to remind everyone to be alert for signs of hepatitis, especially jaundice, look for a yellow tone in the whites of the eyes, and contact your doctor if you are concerned.”
Symptoms of the complication usually begin with diarrhea or illness. Then it can cause the skin and eyes to turn yellow.
The United States has reported 216 cases in 37 states, with Mississippi and Utah being the latest to be added to the growing list.
No deaths or liver transplants have been reported in the past seven days, the Centers for Disease Control and Prevention (CDC) revealed in its weekly update, with the remaining totals at 14 and six, respectively.
The agency has not disclosed where the fatalities occurred due to “confidentiality issues,” but at least one was reported to Wisconsin health officials in the state.
Globally, the UK has now recorded the highest number of fatalities and suspicious cases in any nation, although this may be due to stronger surveillance than other nations.
Top experts fear health officials may not understand what lies behind this quirky pattern, which has sickened at least 520 children worldwide for months since March.
Although mild inflammation of the liver is not uncommon in children, serious illness as seen in these cases is.
Dr. Jason Kindrachuk, an assistant professor of medical microbiology and infectious diseases at the University of Manitoba, Canada, said experts continue to investigate the outbreak worldwide.
He told The Guardian: “The playing field is changing from hour to hour. Inch by inch, we’re starting to find out what the problem is.
“But I don’t think we have all these pieces of the puzzle yet to say ‘okay, that’s what we think is happening.’
The United States and Indonesia have five deaths due to the outbreak, while Palestine and Israel have each recorded one.
Q&A: What is the mysterious global hepatitis outbreak and what’s behind it?
What is hepatitis?
Hepatitis is an inflammation of the liver that is usually caused by a viral infection or liver damage from drinking alcohol.
Some cases resolve on their own, with no ongoing problems, but some can be fatal, forcing patients to need liver transplants to survive.
What are the symptoms?
People with hepatitis usually have fatigue, loss of appetite, nausea, vomiting, abdominal pain, dark urine, light-colored stools, and joint pain.
They may also suffer from jaundice, when the skin and whites of the eyes turn yellow.
Why do experts care?
Hepatitis is usually rare in children, but experts have already detected more cases in the current outbreak than would normally be expected in a year.
The cases are of “unknown origin” and are also serious, according to the World Health Organization.
What are the main theories?
Coinfection
Experts say the cases may be related to adenovirus, usually associated with colds, but more research is ongoing.
This, in combination with Covid infections, could be causing an increase in cases.
About three-quarters of British cases have tested positive for the virus.
Weakened immunity
British experts in charge of investigating the series of diseases believe that the endless cycle of blockages could have played a contributing role.
Restrictions may have weakened children’s immunity due to the reduced social mix, leaving them at increased risk for adenovirus.
This means that even “normal” adenovirus could be causing serious results, because children do not respond to it as they did in the past.
Adenovirus mutation
Other scientists said it could have been the adenovirus that has acquired “unusual mutations”.
This would mean that it could be more transmissible or more able to prevent children’s natural immunity.
New variant of Covid
UKHSA officials included “a new variant of SARS-CoV-2” in their working hypotheses.
Covid has caused liver inflammation in very rare cases during the pandemic, although it has occurred at all ages rather than being isolated in children.
Environmental triggers
The CDC has noted that environmental triggers are still being investigated as possible causes of the disease.
These may include contamination or exposure to certain drugs or toxins.
