580). Both HAV and HEV have been cited as the major causes of the epidemic hepatitis as well as acute sporadic and fulminant hepatitis in these nations. It has been estimated that close to 1000 000 people each year where approximately 2.7% of the deaths a related to the viral Hepatitis and mostly the liver disease and also including liver cancer. Notably, an estimated 57% of liver cirhossis and 78% of liver cancer directly result from HBV and BCV infections (Michael &amp. Jacques, 2004, p. 1). Over the last 40 years increase in the knowledge concerning human viral hepatitis has been so explosive in nature. This began with the discovery of the Australian antigen in mid 1960 (Michael &amp. Jacques, 2004, p. 1). Subsequently, sensitive, rapid, specific and precise immunological assay techniques for the detection of Hepatitis B surface antigens and antibodies to HAV were developed in the 1970s. Such progress led to the identification of a third Hepatitis Virus via exclusion which was tentatively named as a post transfusion non A, non B hepatitis virus. In the late 1970s, hepatitis delta virus was discovered, and later on the advent of molecular biology and the introduction of polymerase chain and viral genome was cloned molecularly and designated HCV (Polis &amp. Barba, 2004, p. 1). The new cloning techniques led to the discovery of HEV and the GB viruses A B and C and even the TT virus. Notably, immunological and molecular probe assays were developed for detection and of these viruses. Egypt has been reported to have the highest Hepatitis prevalence in the world, this figure stands between 10-15% according to the latest statistics (Dalaglish, 2008, p. 6). This is a matter of concern since millions of people living with the viral hepatitis and other millions are at a greater risk. Indeed, most of the people living with the viral disease are unaware of their chronic infection and thus, they are at a high risk of developing severe liver disease which may be unknowingly transmitted to other people. This paper seeks to compare the existing prevention policies and practices between Egypt and Australia, with a view to elucidate on the types of Hepatitis, causes and prevention mechanisms. It is believed that the contents of this paper will encourage development of new and innovative approaches to the future research involving Hepatitis as well provide clear directions for a much better understanding of Hepatitis viruses. Viral hepatitis refers to the liver inflammation which is caused by any of the five hepatitis viruses, namely Hepatitis A, B, C, D and E (Mushahwar, 2004, p. 1). Though all of this viruses cause liver diseases, they vary significantly in terms of natural history, epidemiology, diagnosis, prevention and treatment.&nbsp.Hepatitis A (HAV) is mostly spread through water or food contaminated with the virus. Hepatitis B virus (HBV) and Hepatitis C virus (HCV) are both transmitted via contact with contaminated blood and HBV can also be sexually transmitted (Polis &amp. Barba, 2004, p. 1). As noted, both HBV and HCV can cause severe liver cancer, liver damage as well as an urgent need for liver transplants. In Australia close to 200, 000 people are living with Hepatitis C.
