Hepatitis Outbreak Amongst Children Has Caused Live Transplants and One Death


1 death, 17 liver transplants in multi-country outbreak of hepatitis in children, WHO says

At least 169 cases of acute hepatitis in children aged one month to 16 years old have been identified in an outbreak that now involves 11 countries

Among the cases of acute hepatitis, at least one child has died and 17 children have required liver transplants. It is not yet clear if there has been an increase in hepatitis cases, or an increase in awareness of hepatitis cases that occur at the expected rate but go undetected.

The clinical syndrome among identified cases is acute hepatitis (liver inflammation) with markedly elevated liver enzymes. Many cases reported gastrointestinal symptoms such as abdominal pain, diarrhea and vomiting as well as increased levels of liver enzymes or alanine aminotransaminase and jaundice.

Most reported cases did not have a fever, and the common viruses that cause acute viral hepatitis, such as hepatitis viruses A, B, C, D and E have not been detected in any of these cases.

Hepatitis is inflammation of the liver, a vital organ that processes nutrients, filters the blood and helps fight infections. When the liver is inflamed or damaged, its function can be affected.

Hepatitis is usually caused by a virus, and adenoviruses are a common type of virus spread from person-to-person that can cause a range of mild to more severe illnesses. 

The investigation into the cause needs to focus on factors such as increased susceptibility amongst young children following a lower level of circulation of adenovirus during the COVID-19 pandemic, the potential emergence of a novel adenovirus, as well as SARS-CoV-2 co-infection.

The majority of the cases have been reported in the United Kingdom. There have been 13 cases in Spain, 12 in Israel, nine in the United States and a smaller number of cases confirmed in Denmark, Ireland, the Netherlands, Italy, Norway, France, Romania and Belgium.

On Thursday, the US Centers for Disease Control and Prevention (CDC) issued a health advisory which alerted health care providers and public health authorities of an investigation into acute cases of hepatitis with unknown causes.

The CDC recommended providers consider adenovirus testing in children with hepatitis when the cause is unknown.
