As part of Hepatitis Awareness Month and the first National Hepatitis Testing Day in the U.S. on May 19, the CDC released two reports on protecting patients and workers from healthcare–associated viral hepatitis in Morbidity and Mortality Weekly Report (MMWR), May 18.
“Investigation of Viral Hepatitis Infections Possibly Associated with Health-Care Delivery” — New York City, 2008–2011″  illustrates how the New York City Department of Health and Mental Hygiene developed a system to investigate reports of acute Hepatitis B (HBV) and Hepatitis C (HCV) infections in patients whose infection were caused by healthcare procedures from 2008 to 2011.
The approximately 40 HCV and 600 HBV case reports that the health department receives annually could overwhelm resources, and the report provides examples for “deciding the extent of case investigations which it believes protects the public’s health while conserving the public’s resources.”
The second MMWR report examines outbreaks of HBV infection associated with assisted blood glucose monitoring among residents of assisted living facilities in Virginia.  Infection control practice failures in four assisted living facilities resulted in the transmission of HBV to 31 of 323 susceptible residents. “Attack rates among susceptible residents with diabetes ranged by facility from 14.3% to 71.4%,” according to the report.
