Reporting and Surveillance

CDC is investigating a possible association between pediatric hepatitis and adenovirus infection. Visit CDC’s NCIRD site for information about the investigation: Children with Acute Hepatitis of Unknown Cause.

Adenovirus infections are not nationally notifiable in the United States. Adenovirus infections and outbreaks may not be reported, even if they are diagnosed.


CDC tracks seasonal trends in adenovirus-associated illness through two surveillance systems. Adenovirus typing results are tracked by the National Adenovirus Type Reporting System (NATRS) and untyped adenovirus results are tracked by the National Respiratory and Enteric Virus Surveillance System (NREVSS).
