Outbreak of hepatitis B and hepatitis C virus infections associated with a cardiology clinic, West Virginia, 2012-2014.

Objective: To stop transmission of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections in association with myocardial perfusion imaging (MPI) at a cardiology clinic.

Design: Outbreak investigation and quasispecies analysis of HCV hypervariable region 1 genome.

Setting: Outpatient cardiology clinic.

Hepatitis A Outbreaks in Developed Countries: Detection, Control, and Prevention.

The incidence of hepatitis A virus (HAV) infection has been low in developed countries for decades; however, many adults in these countries are susceptible to HAV infection. In recent years, the global trade of food products originating from HAV-endemic countries resulted in HAV outbreaks associated with imported foods in developed countries. This article aims to review the characteristics of selected HAV outbreaks associated with imported food in developed countries during 2012-2018, and discusses improvements in global public health capabilities and new tools for effective detection, control, and prevention of HAV outbreaks.

Hepatitis B and C virus infections transmitted through organ transplantation investigated by CDC, United States, 2014-2017.

We evaluated clinical outcomes among organ recipients with donor-derived hepatitis B virus (HBV) or hepatitis C virus (HCV) infections investigated by CDC from 2014 to 2017 in the United States. We characterized new HBV infections in organ recipients if donors tested negative for total anti-HBc, HBsAg and HBV DNA, and new recipient HCV infections if donors tested negative for anti-HCV and HCV RNA. Donor risk behaviors were abstracted from next-of-kin interviews and medical records.

Characteristics of Deceased Solid Organ Donors and Screening Results for Hepatitis B, C, and Human Immunodeficiency Viruses - United States, 2010-2017.

The ongoing U.S. opioid crisis has resulted in an increase in drug overdose deaths and acute hepatitis C virus (HCV) infections, with young persons (who might be eligible organ donors) most affected.

The Predictive Value of International Classification of Disease Codes for Chronic Hepatitis C Virus Infection Surveillance: The Utility and Limitations of Electronic Health Records.

Surveillance of chronic hepatitis C virus (HCV) cases faces limitations that result in delays and under-reporting. With increasing use of electronic health records (EHRs), the authors evaluated the predictive value of using (ICD-9) codes to identify chronic HCV cases from EHR data. Longitudinal EHR data from 4 health care systems during 2006-2012 were evaluated.

Using Population Based Hospitalization Data to Monitor Increases in Conditions Causing Morbidity Among Persons Who Inject Drugs.

Epidemics of opioid use and injection drug use (IDU) are associated with an increase in HIV and viral hepatitis infections and overdose deaths in the United States. Persons who inject drugs (PWID) are also at risk for serious infections caused by skin organisms introduced via IDU. We examined National Inpatient Sample hospital discharge data to determine trends in three serious infectious disease-associated conditions that primarily affect PWID in addition to HIV and viral hepatitis: infective endocarditis (IE), central nervous system (CNS) abscesses, and osteomyelitis.

The Financial Burden of Public Health Responses to Hepatitis A Cases Among Food Handlers, 2012-2014.

When food handlers become ill with hepatitis A virus (HAV) infection, state and local health departments must assess the risk of HAV transmission through prepared food and recommend or provide postexposure prophylaxis (PEP) for those at risk for HAV infection. Providing PEP (eg, hepatitis A [HepA] vaccine or immunoglobulin), however, is costly. To describe the burden of these responses on state and local health departments, we determined the number of public health responses to HAV infections among food handlers by reviewing public internet sources of media articles.

Comparison of Three Popular Methods for Recruiting Young Persons Who Inject Drugs for Interventional Studies.

Persons who inject drugs (PWID) are at risk for adverse health outcomes as a result of their drug use, and the resulting social stigma makes this a difficult population to reach for interventions aimed at reducing morbidity and mortality. During our study of adult PWID aged ≤40 years living in San Diego during 2009 and 2010, we compared three different sampling methods: respondent-driven sampling (RDS), venue-based sampling at one syringe exchange program (SEP), and street-based outreach. We compared demographic, socioeconomic, health, and behavioral factors and tested participants for HIV, hepatitis B virus (HBV), and hepatitis C virus (HCV) and compared across the three methods.

Hepatitis C virus transmission in a skilled nursing facility, North Dakota, 2013.

Background: From March-May 2013, 3 cases of acute hepatitis C virus (HCV) infection were diagnosed among elderly patients residing at the same skilled nursing facility (facility A) and who received health care at hospital X during their likely exposure period.

Methods: We performed HCV testing of at-risk populations; quasispecies analysis was performed to determine relatedness of HCV in persons with current infection. Infection control practice assessments were conducted at facility A and hospital X.

Hepatitis A Infections Among Food Handlers in the United States, 1993-2011.

We reviewed news reports of hepatitis A virus (HAV)-infected food handlers in the United States from 1993 to 2011 using the LexisNexis® search engine. Using U.S.

Hepatitis A and B among young persons who inject drugs--vaccination, past, and present infection.

Background: Our study aims were to assess hepatitis A virus (HAV) and hepatitis B virus (HBV) susceptibility and infection among young persons who inject drugs (PWID) who may have been vaccinated as children and to evaluate self-report of HAV and HBV vaccination.

Methods: We recruited PWID aged 18-40 years-old in San Diego during 2009 and 2010 and collected demographic, socioeconomic, health, and behavioral factors. Participants were asked if they had been vaccinated against HAV and HBV, and serum samples were collected for HAV and HBV serologic testing.

Awareness of HCV infection among persons who inject drugs in San Diego, California.

We asked persons who inject drugs questions about HCV, including past testing and diagnosis followed by HCV testing. Of 540 participants, 145 (27%) were anti-HCV positive, but of those who were positive, only 46 (32%) knew about their infection. Asking about previous HCV testing results yielded better results than did asking about prior HCV diagnosis.

Hepatitis A hospitalizations in the United States, 2002-2011.

Unlabelled: Hepatitis A illness severity increases with age. One indicator of hepatitis A illness severity is whether persons are hospitalized. We describe changes in primary hepatitis A hospitalization rates in the United States from 2002-2011, including changes in demographics, secondary discharge diagnoses, and factors affecting hospitalization duration.

Outbreak of hepatitis A in the USA associated with frozen pomegranate arils imported from Turkey: an epidemiological case study.

Background: In May, 2013, an outbreak of symptomatic hepatitis A virus infections occurred in the USA. Federal, state, and local public health officials investigated the cause of the outbreak and instituted actions to control its spread. We investigated the source of the outbreak and assessed the public health measures used.

Hepatitis E virus among persons who inject drugs, San Diego, California, USA, 2009-2010.

Data about prevalence of hepatitis E virus infection in persons who inject drugs are limited. Among 18-40-year-old persons who inject drugs in California, USA, prevalence of antibodies against hepatitis E virus was 2.7%.

Measles Outbreak Associated With International Travel, Indiana, 2011.

Background: Endemic measles was declared eliminated in the United States in 2000, but imported measles cases continue to cause outbreaks. On June 20, 2011, 5 epidemiologically linked measles cases were reported to the Indiana State Department of Health. We investigated to identify additional cases and to prevent further spread.

Assessing compliance with a county board order for third trimester syphilis screening in Maricopa County, Arizona.

Objectives: Due to high rates of congenital syphilis, a Maricopa County board order was issued in 2003 to increase prenatal syphilis screening. The provisions of this order included prenatal syphilis screening during the first prenatal visit, to be repeated during the third trimester, and again at delivery. The purpose of the study was to evaluate syphilis screening practices and barriers to screening among obstetric providers.
