More than 100 cases of hepatitis in children have been confirmed by UK officials and eight children have received a liver transplant since the start of 2022, the UK Health Security Agency (UKHSA) confirmed.
UKHSA's chief medical advisor, Professor Susan Hopkins, said to the BBC: "Transplants in this age group are extremely rare so therefore we are concerned, and we want to understand why this is happening and what else we can do."
The young age of the patients means that the outbreak in cases is not related in any way to the coronavirus vaccine as none of the initial 74 children reported had yet been vaccinated.
