Outbreak of hepatitis A associated with men who have sex with men (MSM), England, July 2016 to January 2017.

Outbreak of hepatitis A associated with men who have sex with men (MSM), England, July 2016 to January 2017. Euro Surveill. 2017 Feb 02;22(5): Authors: Beebeejaun K, Degala S, Balogun K, Simms I, Woodhall SC, Heinsbroek E, Crook PD, Kar-Purkayastha I, Treacy J, Wedgwood K, Jordan K, Mandal S, Ngui SL, Edelstein M Abstract Between July 2016 and January 2017, 37 confirmed cases of hepatitis A with two unique IA genotype strains primarily among men who have sex with men, were reported across eight areas in England and Northern Ireland. Epidemiological and laboratory investigations indicate that these strains may have been imported several times from Spain, with secondary sexual transmission in the United Kingdom. Local and national public health services are collaborating to control this ongoing outbreak. PMID: 28183392 [PubMed - in process]

AbstractHepatitis A, an acute inflammatory liver disease caused by hepatitis A virus (HAV) infection from close contact with infected people, is highly endemic in the Indian subcontinent. Due to poor sanitary conditions, most of the population is exposed to the virus in childhood. At this age, the disease is asymptomatic and provides life-long protection against the disease. Due to rapid socioeconomic development in some areas, however, pockets of the population are reaching adolescence/adulthood without prior exposure to the virus and are thus susceptible to infection. At these ages, infection carries a higher risk of sym...

Opportunistic infections are those that are either more frequent or more severe as a result of the patient’s immunosuppressed condition. Opportunistic infections are, of course, the distinguishing feature of HIV infection, and they can be the cause of serious morbidity and even mortality. Some opportunistic infections can be prevented by vaccination, for example, pneumococcal infection, meningococcal infection, influenza, hepatitis A and B, and varicella. Other major opportunistic infections require prophylactic antibiotics or antiviral medications. In obstetric patients, pneumocystis infections and toxoplasmosis are...

CONCLUSION: Rapid risk assessment indicated that the overall risk to blood safety associated with a small foodborne outbreak of HAV was negligible. Because fresh components collected from donors known to have consumed the affected product were at high risk, these donors were identified via signage in donor centers and deferred. The contribution of factors other than outbreak size to risk management decisions is discussed. PMID: 31642534 [PubMed - as supplied by publisher]

In conclusion, European countries now have more comprehensive national vaccination programs for HCP, however there are still gaps. Given the recent large outbreaks of vaccine-preventable diseases in Europe and the occupational risk for HCP, vaccination policies need to be expanded and strengthened in several European countries. Overall, vaccination policies for HCP in Europe should be periodically re-evaluated in order to provide optimal protection against vaccine-preventable diseases and infection control within healthcare facilities for HCP and patients.

Abstract BACKGROUND: The routes of hepatitis E virus (HEV) transmission have still not been fully clarified. Here, we evaluated the possibility of sexual transmission of HEV, which remains a highly disputed issue. MATERIALS AND METHODS: Hepatitis E virus sexual transmission risk was assessed by comparing the prevalence of HEV infection in a sample of 196 Italian men who have sex with men (MSM) involved in a multi-country hepatitis A virus (HAV) outbreak, and in 3,912 Italian male blood donors selected from the same regions and provinces as the MSM. Selection of study of participants was motivated by the fact ...

Conclusion: Outbreaks of HAV, attributed to person-to-person transmission of strains of HAV that disproportionately affected MSM and were likely to have been imported from international MSM outbreaks, have now occurred in Canada. Genetic sequencing of HAV, risk factor analysis of cases, monitoring trends of vaccine coverage in high-risk groups and initiation of vaccination campaigns that address barriers to HAV preexposure vaccine coverage in the MSM population may prevent future outbreaks.

AbstractFoodborne viral diseases are a major public health threat and pose a huge burden on the economies of both developed and developing countries. Enteric viruses are the causative agents of most foodborne illnesses and outbreaks. Egypt is classified by WHO among the regions with intermediate to high endemicity for various enteric viruses. This is manifested by the high prevalence rates of different enteric virus infections among Egyptian population such as Hepatitis A and E viruses, human rotaviruses, human noroviruses, human astroviruses, and human adenovirus. Recently, a number of foodborne gastroenteritis and acute ...

Authors: Kang SH, Kim MY, Baik SK Abstract Until 1995, the incidence of symptomatic acute hepatitis A was minimal and there were no cases of national outbreak in Korea. However, there was a nationwide outbreak of hepatitis A that peaked in 2009. In 2019, a total of 10,083 cases of acute hepatitis A were reported for seven months of the year according to the Korea Center for Disease Control and Prevention. This may be attributed to the proportion of susceptible subjects in the Korean population, as about 10 years have passed since herd immunity was induced by the epidemic occurring during the late 2000s. Recent stud...

te; J Abstract Stabilizing paper matrix methods for retaining nucleic acid from inactivated clinical specimens offer a solution for molecular diagnostics when specimens may be stored or shipped at ambient temperature. We developed cellulose disks (UNEXP) saturated with a total nucleic acid extraction buffer (UNEX) modified from a previously developed lysis buffer for multiple enteric pathogens. Infectivity of hepatitis A virus, adenovirus and poliovirus was destroyed after 2-3 hours incubation at room temperature on the UNEXP disks. Norovirus RNA could be detected in UNEXP-eluted nucleic acids by reverse tr...
