The inactivation kinetics of cell-associated and dispersed hepatitis A virus (HAV) by free chlorine and monochloramine were compared. Cell-associated HAV was always inactivated more slowly than dispersed HAV. Values of C x T or other disinfection criteria for inactivation of HAV and other enteric viruses should be based on viruses associated with cells or other solids because they are better mo...

BACKGROUND Hepatitis A virus (HAV) and Hepatitis E virus (HEV) are both transmitted by the fecal-oral route and are known as the leading causes of acute viral hepatitis in the world, especially in developing countries. There is a lack of updated data on HAV and HEV seroprevalence in Iran. OBJECTIVES The aim of this study was to determine the seroprevalence of HAV and HEV among a group of bloo...

OBJECTIVE The number of adult hepatitis A cases has progressively been increasing during the last several years in Korea. The aim of the present study was to describe the recent clinical features of hepatitis A and the seroprevalence of hepatitis A virus (HAV), and to discuss HAV vaccine strategy in Korea. METHODS Retrospective analysis of clinical characteristics of hepatitis A from 109 pati...

We investigated the seroprevalence of hepatitis A virus (HAV) and hepatitis E virus (HEV) infection in subjects living in the community of Manguinhos, Rio de Janeiro, Brazil, and assisted at the Health Unit of Escola Nacional de Saúde Pública, Fundação Oswaldo Cruz. After formal consent, individuals were submitted to an interview using a standardized questionnaire. Anti-HAV and anti-HEV antibod...

Age-related seroprevalence studies that have been conducted in Brazil have indicated a transition from a high to a medium endemicity of hepatitis A virus (HAV) infection in the population. However, most of these studies have focused on urban populations that experience lower incidence rates of HAV infection. In the current study, the prevalence of anti-HAV antibodies was investigated in childre...

Hepatitis A virus (HAV) is the most common cause of acute viral hepatitis in the world. Rarely, acute infection may persist for a long time. Autoimmune hepatitis (AIH) may provide anti-HAV IgM positivity detection for a prolonged time. On the other hand, HAV as an infectious agent may also trigger AIH. Here we presented a case which seemed like a simple acute viral hepatitis A infection at the ...

AIM To study the differences in immune response and cytokine profile between acute liver failure and self-limited acute hepatitis. METHODS Forty-six patients with self-limited acute hepatitis (AH), sixteen patients with acute liver failure (ALF), and twenty-two healthy subjects were involved in this study. The inflammatory and anti-inflammatory products in plasma samples were quantified using...

conclusions there are few studies on the prevalence of viral hepatitis in the general population of iran. most of the reports are from specific groups of patients. further epidemiologic studies on the general population of iran are recommended to discover the real burden of viral hepatitis. context viral hepatitis is still considered as a major health concern. defining the extent of the burden ...

Organ transplant recipients with chronic hepatitis B or hepatitis C virus infection may be at increased risk of fulminant hepatitis A. Liver transplant (LTX) recipients, renal transplant (RTX) recipients, and healthy controls received 2 doses of hepatitis A vaccine 6 months apart. Anti-hepatitis A virus (anti-HAV) seroconversion after the primary dose occurred in 41% of the LTX patients, 24% of...

Aim: Hepatitis B vaccination since 1998 and hepatitis A 2012 is available in the childhood routine program Turkey. There no vaccine for C yet. The seroprevalence of A, B, differs between regions. For this reason, each region should assemble its own rates. Therefore, study aimed to determine children Kastamonu province, evaluate whether there a change prevalence according years patient age, revi...
