MMWR - Investigation of Viral Hepatitis Infections Possibly Associated with Health-Care Delivery — New York City, 2008–2011
Public health investigations of cases of Hepatitis B virus (HBV) and hepatitis C virus (HCV) infection suspected to be associated with health-care delivery play an essential role in identifying unsafe practices and controlling health-care–associated viral hepatitis transmission. However, these investigations are resource intensive, and frequently overwhelm health department resources. Over many years, the New York City Department of Health and Mental Hygiene (DOHMH) developed a systematic approach to guide investigation and public health response to case reports of acute HBV or HCV infection in patients whose infection was potentially associated with health-care delivery. In this approach, the least resource-intensive investigation components are conducted for each case, and decisions to expand the investigation to more resource-intensive components are guided by the likelihood that a single case report represents a cluster of health-care–associated infections (HAIs). This report describes the DOHMH approach in the context of two single case reports.
MMWR - Multiple Outbreaks of Hepatitis B Virus Infection Related to Assisted Monitoring of Blood Glucose Among Residents of Assisted Living Facilities — Virginia, 2009–2011
Between Feb.2009 and Nov.2011, the Virginia Department of Health (VDH) was notified of acute hepatitis B virus (HBV) infections occurring in residents of four separate assisted living facilities (ALFs). In each outbreak, the initial acute HBV infections were identified through routine viral hepatitis surveillance. VDH conducted epidemiologic and laboratory investigations of these reports. Infection control practices, particularly surrounding assisted monitoring of blood glucose (AMBG), were assessed by direct observation and staff member interviews. Further investigation and subsequent screening of ALF residents for hepatitis B uncovered additional acute HBV infections at each of the ALFs. All acute HBV infections were among residents receiving AMBG for management of diabetes. AMBG is safe when properly performed, but lapses in infection prevention practices during AMBG were identified at three of the four facilities. These outbreaks highlight the role of hepatitis B surveillance in detecting disease outbreaks and the need for a comprehensive strategy to prevent HBV transmission in ALFs, including vaccination, improved infection control oversight at ALFs, appropriate training of staff members performing AMBG, and prompt investigation of acute HBV infections.
MMWR - Notes from the Field: Hepatitis C Virus Infections Among Young Adults — Rural Wisconsin, 2010
During Nov. 2010, Wisconsin Division of Public Health (DPH) staff members noted the number of hepatitis C virus (HCV) infections reported annually among persons aged <30 years in six contiguous rural counties of Wisconsin had increased from an average of eight cases per year during 2004–2008 to an average of 24 cases per year during 2009–2010. To understand factors associated with this increase, DPH, local health departments, and CDC investigated the epidemiologic and laboratory characteristics of 25 cases reported during 2010 among adults aged <30 years who resided in these six counties.
News Release: Statement from HHS Assistant Secretary for Health Dr. Howard Koh about Hepatitis Testing Day and the Hepatitis Risk Assessment
May is Hepatitis Awareness Month
During the month of May, CDC’s Division of Viral Hepatitis (DVH) will be observing Hepatitis Awareness Month and the first ever national Hepatitis Testing Day on May 19th.
