CDC and partners ensure rapid and coordinated surveillance, detection, and response to hepatitis outbreaks.

DVH laboratory branch participates in outbreak investigations related to hepatitis viruses by performing routine and state of the art serologic and molecular methodologies on clinical samples collected from affected patients. An epidemiologist from the division coordinates all outbreak investigation related activities including submitting a study request and sharing of laboratory results with the state health departments. CDC staff are always available for consultation including discussion of testing algorithms for specific notification settings.

Hepatitis A Outbreaks

This list represents hepatitis A outbreak investigations since 2013 where CDC supported or led the investigation. For a comprehensive listing of reported hepatitis A outbreaks, see the Foodborne Outbreak Online Database (FOOD) tool and under the etiology search option, select hepatitis.

2016 - Multistate outbreak of hepatitis A linked to frozen strawberries

August 2016 - Outbreak of hepatitis A in Hawaii linked to raw scallops

May 31, 2013 - Multistate hepatitis A virus infections linked to pomegranate seeds from Turkey

Healthcare-associated Outbreaks

Upon consultation CDC can provide assistance to health departments during investigation, and share best practices based on many states’ previous experiences with issues such as: infection control breaches previously associated with transmissions in specific settings and observation recommendations, guidance for notification messages including specific populations to screen, and guidance on laboratory testing and molecular genetic investigation.

This manuscript suggests an approach to follow-up of infection control breaches that focuses on the risk of bloodborne pathogen transmission.

Healthcare-Associated Hepatitis B and C Outbreaks Reported to CDC through 2015

Hepatitis in young injection drug users

The highest reported incidence of acute hepatitis C in the United States is now among persons aged 20–29 years. In recent years, there has been an emerging HCV epidemic among young PWIDs, particularly in rural and suburban settings. Further reading.
