The UK has also identified around 163 children with acute hepatitis of unknown cause. At least 20 countries reported cases last week, according to the WHO.
The ECDC said in its update that the cause of these hepatitis cases is “still under investigation”. A possible association with current adenovirus infection has been found in cases in the UK in particular, but other hypotheses and possible co-factors are being investigated. Most cases continue to be reported as unlinked sporadic cases.”
Hepatitis, which is inflammation of the liver, is usually caused by one of the hepatitis viruses – hepatitis A, B, C, D or E. In these new cases, however, the typical causes of hepatitis hepatitis were excluded. The ECDC report did not specify the percentage of global cases in which the child tested positive for adenovirus, but adenovirus was detected in about half of cases in the US and UK. United.
The first US cases reported during the outbreak occurred in Alabama in October, and all of the children, ages 1 to 6, tested positive for the adenovirus. Adenoviruses are common and usually cause cold-like and gastrointestinal symptoms. Prior to these cases, adenoviruses were not known to cause hepatitis in healthy children, according to the CDC.
Last week, the CDC said it was working with state health departments and “investigators are examining a possible relationship to adenovirus type 41 infection.”
“It is not yet clear whether there has been an increase in the number of cases of hepatitis in children or improvements in case detection. It is not unusual for the cause of some cases of hepatitis in children remains unknown,” the CDC added.
The CDC has also released advice for parents to protect their children.
