Background: An estimated 20 000 new hepatitis B virus (HBV) infections occur each year in the United States. We describe the results of enhanced surveillance for acute hepatitis B at 7 federally funded sites over a 6-year period.

Methods: Health departments in Colorado, Connecticut, Minnesota, Oregon, Tennessee, 34 counties in New York state, and New York City were supported to conduct enhanced, population-based surveillance for acute HBV from 2006 through 2011.

Background: Drug diversion by health care personnel poses a risk for serious patient harm. Public health identified 2 patients diagnosed with acute hepatitis C virus (HCV) infection who shared a common link with a hospital. Further investigation implicated a drug-diverting, HCV-infected surgical technician who was subsequently employed at an ambulatory surgical center.

Introduction: The risk of acute hepatitis B among adults with diabetes mellitus is unknown. We investigated the association between diagnosed diabetes and acute hepatitis B.

Methods: Confirmed acute hepatitis B cases were reported in 2009-2010 to eight Emerging Infections Program (EIP) sites; diagnosed diabetes status was determined.

Objectives: Both HIV and hepatitis C virus (HCV) can be transmitted through percutaneous exposure to blood in similar high-risk populations. HCV and HIV/AIDS surveillance databases were matched in Colorado, Connecticut, and Oregon to measure the frequency of co-infection and to characterize coinfected people.

Methods: We defined a case of HCV infection as a person with a reactive antibody for hepatitis C, medical diagnosis, positive viral-load test result, or positive genotype reported to any of three state health departments from the start of each state's hepatitis C registry through June 30, 2008.

Surveillance for hepatitis C virus infection in 6 US sites identified 20,285 newly reported cases in 12 months (report rate 69 cases/100,000 population, range 25-108/100,000). Staff reviewed 4 laboratory reports per new case. Local surveillance data can document the effects of disease, support linkage to care, and help prevent secondary transmission.
