Adenovirus F41, the main suspect in acute childhood hepatitis


  • An adenovirus, F41, seems to cause acute childhood hepatitis, but research continues

  • The outbreak already affects more than 200 children worldwide, 22 in Spain

  • Symptoms that should alert us: yellow skin and whites of the eyes and cola-colored urine

With confirmation of a third case in Galicia of severe childhood hepatitis – a minor who was diagnosed with the disease in February and who is already asymptomatic and with normalized blood tests — they are already 22 affected Spain, and around 200 worldwide. The ailment appears to be caused by a adenovirus, the f41, but investigation is ongoing. The only certainty is that It is not a consequence of the covid vaccine.

The main symptoms of a serious picture of hepatitis

When the pandemic gives us a break, a new health alert spreads throughout the planet: cases of acute childhood hepatitis whose origin is currently a mystery and whose symptoms are very recognizable.

“Children get colored yellowboth the coloration of the fur like the white of eyes”, explains Quique Bassat, pediatrician and epidemiologist. Pediatrician Carlos Príncipe indicates that we should be concerned about “a picture in which a child quickly turns yellow and has cola-colored urine So we do care.”

What causes acute childhood hepatitis?

detected at least 200 cases in 16 countries. A minor has died y 20 have needed a liver transplant, one of them in Spain where there is already 22 contagions. Given these data, clues are sought to clarify the mystery and so far only one has been found. “In some of these cases, a virus has been found that is the adenovirusBassat points out.

Along the same lines, Príncipe says: “It seems evident that there must be a cause-effect. In the most severe cases, the cepa f41”.

Although the adenovirus f41 is the main suspect, something else is being sought to explain why a virus that normally only causes gastroenteritis or mild colds causes hepatitis grave.

“For example, one of the cases was a child who had received chemotherapy for leukemia, with which his levels of defenses they were low,” says Príncipe.

The lower immune response, could it be due to overprotection during the pandemic? The hypothesis is not completely convincing because, according to Bassat, “it does not explain why we have not had outbreaks of many other microorganisms that are much more easily transmitted and that could be causing a lot of disease.”

Others hypothesis They’re a mutation of the adenovirus o environmental factors, such as exposure to toxic. What is totally ruled out is that hepatitis is a consequence of vaccination against covid.

They rule out that it is an effect of the coronavirus vaccine

“What we know for sure is that it has nothing to do with the vaccinewhich is not a secondary effect of the vaccine because the vast majority of children who have had these episodes were not vaccinated, “adds Bassat.

It is also clear how contagion occurs. According to Bassat, it occurs among “children who have been in contact with their stool, the smallest children who have not washed their hands well transmit it through contact. To prevent, explains Príncipe, “we must take extreme measures of hygienebut with everything”.

Despite the health alert, doctors want to reassure. Javier Massaguer, medical director of HM Nens Hospital, states: “Los Sanitary we are with total tranquility because we see that we do not have any number of cases that makes us be in alarm.”

At the moment there are few certainties, but the examination of the livers of transplant patients can help to clear up the mystery.
