Hepatitis A is caused by the hepatitis A virus (HAV). Transmission occurs by the faecal-oral route, either by direct contact with an HAV-infected person or by ingestion of HAV-contaminated food or water. Hepatitis A outbreaks are uncommon in Australia. In 2008, Victoria experienced an outbreak of hepatitis A due to an infected food handler.

In this study, an immunomagnetic capture method and a real-time reverse transcription-PCR assay were used to quantify hepatitis A virus (HAV) in green onion and strawberry rinses. This combined protocol detected as low as 0.5 PFU HAV in produce rinses and concentrated HAV levels up to 20-fold.

In October 2011, two primary cases of hepatitis A virus (HAV) infection with identical HAV genotype IB strains to those seen in other outbreaks associated with semi-dried tomatoes were reported in England. Both cases had consumed semi-dried tomatoes. Epidemiological investigations revealed two additional cases of genotype IB strains with different sequences who also reported having consumed sem...

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...

Hepatitis A virus (HAV) infection is common in Southeast Asia, and most of the inhabitants acquire a lifelong immunity as a result of natural infection during childhood. However, the age-specific seroprevalence is changing with development of socioeconomic and hygiene status in this area and the infection is predicted to shift to adulthood with more severe clinical manifestations in the future....

The purpose of the present analysis is to calculate and compare the costs and results of the implication of the inactivated vaccine against hepatitis A virus (HAV) in the Bulgarian healthcare setting in the period of 2002-2012. A combined pharmacoeconomic and epidemiological study was performed on the basis of the prevalence of hepatitis A infection in this 10-year period. The investments in th...

Today, chronic viral hepatitis is considered as a public health problem in the world. Totally, 5% of the world population, especially in Asia and Africa suffer from this problem. The prevalence of acute hepatitis in America is 0.1-0.2 percent, 50% of those with hepatitis C (HCV) and 5-10% of them with hepatitis B (HCV) develop chronic hepatitis. Determining HBV and HCV genotypes is important to...

Hepatitis viruses (HAV, HBV, HCV, HDV and HEV) are attributed to a wide spectrum of acute and chronic liver diseases, including carcinomas. Worldwide, >250 million become chronically infected by HBV and ~150 million by HCV every year. Though, new hepatotropic viruses, such as HGV, GBV, TTV and SENV are identified in chronic liver diseases, thousands still suffer of unknown etiology. Despite a p...

Methods Matched case control study including patients with JIA and controls. All subjects received two doses of inactivated anti-HAV at 0 and 6 months. Seroconversion rates and anti-HAV IgG antibodies were assessed 4 weeks after the first dose and at 4 and 52 weeks after the last dose. The protective level of IgG antibodies against HAV was set as antiHAV>20mIu/ml. Children were monitored for lo...

Seroprevalence data on viral hepatitis in the general population vary widely. The aim of this study was to determine the prevalence of hepatitis A (HAV), hepatitis B (HBV) and hepatitis C (HCV) viruses in the general Croatian adult population undergoing routine check-ups. The seroprevalence of anti-HAV, anti-HBc and anti-HCV was 40.5%, 7.0% and 0.9%, respectively. HBsAg was found in 0.7% and an...
