Ongoing hepatitis A among men who have sex with men (MSM) linked to outbreaks in Europe in Tel Aviv area, Israel, December 2016 - June 2017

Between December 2016 and June 2017, 19 Hepatitis A virus (HAV)-positive cases, 17 of which were among men who have sex with men (MSM) were identified in the Tel Aviv area. Seven of the 15 sewage samples collected between January and June 2017 were also HAV-positive. All sequences clustered with two of the three strains identified in the current European HAV outbreak. We demonstrate that despite an efficient vaccination programme, HAV can still be transmitted to an unvaccinated high-risk population.

This report analyzes drinking water-associated hepatitis A outbreaks reported to the Waterborne Disease and Outbreak Surveillance System (WBDOSS) during 1971-2017. During that period, 32 outbreaks resulting in 857 cases were reported, all before 2010. Untreated ground water was associated with 23 (72%) outbreaks, resulting in 585 (68.3%) reported cases. Reported outbreaks significantly decreased after introduction of Advisory Committee on Immunization Practices (ACIP) hepatitis A vaccination recommendations* and U.S. Environmental Protection Agency's (USEPA) public ground water system regulations.† Individual water ...

Background: Henoch-Sch önlein purpura (HSP), an IgA vasculitis, most commonly occurs in children. The IgA immune complex deposition is commonly triggered by infection but also has been seen following vaccination. In 2018, Louisville, Kentucky had an outbreak of hepatitis A with over 950 reported cases and 6 deaths. Vacci nation was strongly encouraged and available to the community as a response to the outbreak.

There is a widespread outbreak of hepatitis A in communities across the U.S. "Hepatitis A is a highly contagious virus that can cause infection and inflammation in the liver," says Dr. Stacey Rizza, an infectious diseases specialist at Mayo Clinic. "It's transmitted through food, water, and through an oral-fecal route." Anyone who has not been vaccinated is [...]

nership A literature review was conducted to identify evidence of cases and outbreaks of vaccine-preventable diseases (VPDs) that have been reported from on board ships and the methods applied on board for prevention and control, worldwide, in 1990 to April 2019. Moreover, evidence from seroprevalence studies for the same diseases were also included. The literature review was conducted according to Preferred Reporting Items for Systematic reviews (PRISMA) guidelines. A total of 1795 cases (115 outbreaks, 7 case reports) were identified, the majority were among crew (1466/1795, 81.7%) and were varicella cases (1497, 83....

Publication date: Available online 13 June 2019Source: EpidemicsAuthor(s): Giorgio GuzzettaAbstractA major outbreak of Hepatitis A Virus (HAV) has swept through Europe between mid-2016 and 2017, mainly within the community of men who have sex with men (MSM). Over the same period, about 1,000 outbreak-related cases of acute Hepatitis A (AHA) were recorded in Lazio region, Italy.We calibrated a Bayesian model to reconstruct likely transmission events within all 44 households where multiple infections were recorded, representing a total of 103 cases from the HAV outbreak in Lazio. Based on information on the observed times of...

Publication date: May 2019Source: Advances in Chronic Kidney Disease, Volume 26, Issue 3Author(s): Maria Andrievskaya, Adrienne Lenhart, Junior UdumanIn the past decade, hepatitis A has been considered a rare disease in the United States, largely due to targeted vaccination of at-risk children. Evolving epidemiology has resulted in decreasing immunity and increasing hepatitis A infections among adults who are more likely to experience severe disease. A surge in outbreaks has been noted in the past 2 years, resulting in a high volume of hepatitis A related hospitalizations and complications in otherwise healthy individ...

Authors: Mauro MV, Greco F, Tenuta R, Apuzzo G, Costantino A, Bruni R, Equestre M, Ciccaglione AR, Giraldi C, Mastroianni A Abstract From April to October 2017, 27 cases of Hepatitis A (HA), 22 male and 5 female, were reported in Cosenza (South Italy). The median age of cases was 32 years (range 3-49 years). Out of 21 male adults, 14 were identified as men who have sex with men (MSM). Phylogenetic analysis was conducted in 15 cases and revealed two distinct sequences of genotype IA linking to clusters recognised in MSM in other European countries in 2016; genotype IB was recognized in only 2 cases. The report confi...

Unfortunately, some vaccines provide only partial protection or in some cases vaccine-mediated immunity may wane rapidly, resulting in either increased susceptibility to that disease or a requirement for more booster vaccinations in order to maintain immunity above a protective level. The durability of a...
