conclusions vaccination of non-immune individuals against hav infection in high risk groups especially hemophilia and thalassemia patients is recommended. results did not show any differences about seroprevalence of hev among iranian general population. results anti-hav igg antibodies were observed more frequently in thalassemia patients (60/64; 93.8%) than in hemophilia patients (104/155; 67.1...

Hepatitis A virus (HAV) infection is rarely fatal except in patients with chronic liver disease. In the case reported here, an elderly women died of HAV infection 12 years after incomplete HAV vaccination. The possible role of a concordant Rift Valley fever virus infection acquired in Kenya is discussed.

We report a hepatitis A (HAV) and dengue virus (DENV) co-infection in Russian man who had been traveling to Dominican Republic. At admission to the hospital hemorrhagic and jaundice symptoms were observed in patient. PCR tests of blood serum and urine revealed RNA dengue virus type 3, HAV RNA, anti-HAV-IgM.

UNLABELLED Describing the viral diversity of wildlife can provide interesting and useful insights into the natural history of established human pathogens. In this study, we describe a previously unknown picornavirus in harbor seals (tentatively named phopivirus) that is related to human hepatitis A virus (HAV). We show that phopivirus shares several genetic and phenotypic characteristics with H...

background hepatitis a is often asymptomatic in children, however it can become a serious disease in adults. for countries that do not have a universal vaccination strategy targeted vaccination for high risk groups is recommended. health workers could be at a higher risk of infection with hepatitis a virus (hav) compared to the general population. the aim of this study is to investigate the ser...

Hepatitis A virus (HAV) infection typically resolves within 4-7 wk but symptomatic relapse occurs in up to 20% of cases. Immune mechanisms that terminate acute HAV infection, and prevent a relapse of virus replication and liver disease, are unknown. Here, patterns of T cell immunity, virus replication, and hepatocellular injury were studied in two HAV-infected chimpanzees. HAV-specific CD8(+) T...

Waste collectors have a theoretical risk of Hepatitis A virus infection. The aim of the study was to assess the prevalence and risk factors of hepatitis A virus infection (HAV) among municipal solid waste workers (MSWWs) in a municipality of central Greece. A seroprevalence study of HAV was conducted among 208 employees (100 waste collectors and 108 municipal gardeners) of a municipality in ce...

Due to improvements in socio-economic and sanitation conditions, Thailand has undergone a change from hyperendemicity to intermediate endemicity for hepatitis A virus infection, leaving a large part of the adult population without immunity. At the same time, the country is still highly endemic for hepatitis B and especially in the northeast, hepatitis C virus infection both of which when acquir...

Hepatitis A is a common viral liver disease and brings serious health and economic problems as its epidemiologic pattern changes over time. National serosurveys from developed countries have indicated a decline in HAV (hepatitis A virus) seroprevalence over time due to the improvement of economic and sanitation levels. The hepatitis A virus (HAV) immunity rate was surveyed throughout an eleven-...

OBJECTIVE To estimate the prevalence of hepatitis A virus (HAV) antibodies among Montreal street youth. METHOD Anti-HAV antibody testing was performed on blood samples from a hepatitis B and C study conducted among street youth in 1995-96. RESULTS Among the 427 youth aged 14 to 25 years, prevalence of HAV antibodies was 4.7% (95% confidence interval [CI]: 2.9%-7.2%). A multivariate logistic...
