Abstract
This AMSSM position statement update is directed toward health care providers of patients involved in sport and exercise. There have been significant advances in clinical and scientific research in the understanding of blood-borne pathogens (BBPs), and this update incorporates these advancements. This document is intended as a general guide to clinical practice based on the current state of evidence, while acknowledging the need for modification as new knowledge becomes available. Confirmed transmission of BBPs during sport is exceedingly rare. There are no well-documented reports of HIV, hepatitis C virus, or hepatitis D virus transmission during sport. There is also no evidence for universal testing for BBPs as a specific requirement for participation in sports. Competitive athletes and nonathletes should follow appropriate general public health agency recommendations for screening for BBPs, considering their individual risk factors and exposures. Standard (universal) precautions must be followed by those providing care to athletes. Exercise and athletic participation can help promote a healthy lifestyle for persons living with BBPs. Those with acute symptomatic BBP infection should limit exercise intensity based on their current health status. Education is the key tool for preventing BBP transmission. Research gaps include evaluation of the prevalence of BBP infections in competitive athletes, the effects of long-term, intense training on infected athletes, and the effects of BBP treatment therapies on performance.

Seroconversion rates among health care workers exposed to hepatitis C virus-contaminated body fluids: The University of Pittsburgh 13-year experience. Am J Infect Control 2017; 45:1001-1005. [PMID: 28449917 DOI: 10.1016/j.ajic.2017.03.011] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2016] [Revised: 03/13/2017] [Accepted: 03/14/2017] [Indexed: 10/19/2022]
Abstract
BACKGROUND Hepatitis C virus (HCV) transmission to health care personnel (HCP) after exposure to a HCV-positive source has been reported to occur at an average rate of 1.8% (range, 0%-10%). We aimed to determine the seroconversion rate after exposure to HCV-contaminated body fluid in a major U.S. academic medical center. METHODS A longitudinal analysis of a prospectively maintained database of reported occupational injuries occurring between 2002 and 2015 at the University of Pittsburgh Medical Center was performed. Data collected include type of injury and fluid, injured body part, contamination of sharps, resident physicians' involvement, and patients' hepatitis B virus (HBV), HCV, and HIV status. RESULTS A total of 1,361 cases were included in the study. Most exposures were caused by percutaneous injuries (65.0%), followed by mucocutaneous injuries (33.7%). Most (63.3%) were injuries to the hand, followed by the face and neck (27.6%). Blood exposure accounted for 72.7%, and blood-containing saliva accounted for 3.4%. A total of 6.9% and 3.7% of source patients were coinfected with HIV and HBV, respectively. The HCV seroconversion rate was 0.1% (n = 2) because of blood exposure secondary to percutaneous injuries. CONCLUSIONS This study provides the largest and most recent cohort from a major U.S. academic medical center. The seroconversion rates among HCP exposed to HCV-contaminated body fluids was found to be lower than most of the data found in the literature.

Abstract
According to 2009 statistics, the human immunodeficiency virus (HIV) infected an estimated 86,500 individuals within the UK, although around one-quarter were unaware of their infection. In the majority of cases, it is now considered a long-term controllable but incurable infection. Indeed, most HIV-positive individuals are able to work. Employment is across most, if not all, workforce sectors and protection against workplace discrimination is provided by the Equality Act 2010. Issues including confidentiality, workplace adjustments, vaccinations and travel restrictions may be relevant to the occupational health of HIV-positive workers. There are special considerations concerning HIV-infected health care workers, including avoidance of performing exposure-prone procedures. Prevention of HIV acquisition in the workplace is relevant to a diverse range of occupational environments, and HIV post-exposure prophylaxis should be considered after potential HIV exposure incidents. If a worker contracts HIV by occupational means, financial help may be available.

Abstract
Hepatitis C (HCV) is the disease that has affected around 200 million people globally. HCV is a life threatening human pathogen, not only because of its high prevalence and worldwide burden but also because of the potentially serious complications of persistent HCV infection. Chronicity of the disease leads to cirrhosis, hepatocellular carcinoma and end-stage liver disease. HCV positive hepatocytes vary between less than 5% and up to 100%, indicating the high rate of replication of viral RNA. HCV has a very high mutational rate that enables it to escape the immune system. Viral diversity has two levels; the genotypes and Quasiaspecies. Major HCV genotypes constitute genotype 1, 2, 3, 4, 5 and 6 while more than 50 subtypes are known. All HCV genotypes have their particular patterns of geographical distribution and a slight drift in viral population has been observed in some parts of the globe.

Abstract
Molecular epidemiological studies of hepatitis C virus (HCV) in the Caribbean may help to specify the origin and spread of HCV infection. Indeed, the Caribbean population is intermixed from European and African origins and geographically close to the American continent. We characterized HCV genotypes in the Caribbean island of Martinique. HCV genotypes were analyzed by sequencing or reverse hybridization in the 5' noncoding region (5'NC) in 250 HCV-monoinfected and 85 HCV-human immunodeficiency virus (HIV)-coinfected patients. In addition, sequencing in the nonstructural 5B (NS5B) gene was required to determine the subtype or to perform phylogenetic analysis in selected samples. Genotypes 1 to 6 were found, respectively, in 84.4, 6.8, 5.2, 2.8, 0.4, and 0.4% of 250 HCV-monoinfected patients and in 71.7, 7.1, 15.3, 5.9, 0, and 0% of 85 HCV-HIV-coinfected patients. HCV-1b was found in 66.4% of the HCV-monoinfected patients and was associated with blood transfusion, whereas HCV-1a was detected in 41.2% of the HCV-HIV-coinfected patients and was associated with intravenous drug use (IVDU). The HCV-3 strains belonged to subtype 3a and were linked to IVDU. Phylogenetic analyses were focused on HCV-2 and HCV-4, which are common in Africa. Two opposite patterns were evidenced. NS5B sequences from 19 HCV-2 isolates were affiliated with many different subtypes described either in Europe or in West Africa, suggesting an ancient radiation. In contrast, seven of the nine HCV-4 NS5B sequences ranged within HCV-4a and HCV-4d clusters spreading in continental France by the IVDU route. Epidemiological data demonstrate the recent introduction of HCV-4a and -4d subtypes into the Caribbean.

Abstract
Hepatitis C virus (HCV) infection is a significant contemporary health problem in the United States and elsewhere. Because it is primarily transmitted via blood, hepatitis C infection presents risks for both nosocomial transmission to patients and occupational spread to health care workers. Recent insights into the pathogenesis, immunopathogenesis, natural history, and treatment of infection caused by this unique flavivirus provide a rationale for the use of new strategies for managing occupational hepatitis C infections when they occur. This article reviews this developing information. Recently published data demonstrate success rates in the treatment of "acute hepatitis C syndrome" that approach 100\%, and although these studies are not directly applicable to all occupational infections, they may provide important clues to optimal management strategies. In addition, the article delineates approaches to the prevention of occupational exposures and also addresses the difficult issue of managing HCV-infected health care providers. The article summarizes currently available data about the nosocomial epidemiology of HCV infection and the magnitude of risk and discusses several alternatives for managing exposure and infection. No evidence supports the use of immediate postexposure prophylaxis with immunoglobulin, immunomodulators, or antiviral agents. Based on the very limited data available, the watchful waiting and preemptive therapy strategies described in detail in this article represent reasonable interim approaches to the complex problem of managing occupational HCV infections, at least until more definitive data are obtained.

Abstract
Exposure to human immunodeficiency virus (HIV) can occur in a number of situations unique to, or more common among, children and adolescents. Guidelines for postexposure prophylaxis (PEP) for occupational and nonoccupational (eg, sexual, needle-sharing) exposures to HIV have been published by the US Public Health Service, but they do not directly address nonoccupational HIV exposures unique to children (such as accidental exposure to human milk from a woman infected with HIV or a puncture wound from a discarded needle on a playground), and they do not provide antiretroviral drug information relevant to PEP in children. This clinical report reviews issues of potential exposure of children and adolescents to HIV and gives recommendations for PEP in those situations. The risk of HIV transmission from nonoccupational, nonperinatal exposure is generally low. Transmission risk is modified by factors related to the source and extent of exposure. Determination of the HIV infection status of the exposure source may not be possible, and data on transmission risk by exposure type may not exist. Except in the setting of perinatal transmission, no studies have demonstrated the safety and efficacy of postexposure use of antiretroviral drugs for the prevention of HIV transmission in nonoccupational settings. Antiretroviral therapy used for PEP is associated with significant toxicity. The decision to initiate prophylaxis needs to be made in consultation with the patient, the family, and a clinician with experience in treatment of persons with HIV infection. If instituted, therapy should be started as soon as possible after an exposure-no later than 72 hours-and continued for 28 days. Many clinicians would use 3 drugs for PEP regimens, although 2 drugs may be considered in certain circumstances. Instruction for avoiding secondary transmission should be given. Careful follow-up is needed for psychologic support, encouragement of medication adherence, toxicity monitoring, and serial HIV antibody testing.
