CDC updates testing guidance for hepatitis of unknown origin in children

The Centers for Disease Control and Prevention Friday updated its April testing guidance for clinicians treating children with hepatitis of unknown cause. The agency is investigating 109 potential hepatitis cases of unknown cause in U.S. children since last October, including five deaths. More than 90% of the patients were hospitalized, 14% received liver transplants and more than half had a confirmed adenovirus infection, but officials still don’t know the actual cause of their hepatitis and cautioned that it may take time to assess the evidence and learn more. Potential cases also have been reported in the United Kingdom and other countries.
