Core Tip

Core tip: This is the first epidemiologic report on hepatitis E virus (HEV) in Israel. This report demonstrates the significant presence of autochthonous acute HEV in Israel, serving as an example of occurrence in an industrialized country. Suspected risk factors in Israel include consumption of water and food in areas with poor sanitation, exposure to animals and eating a non-Kosher meat. The high risk group for fulminant hepatitis was pregnant women in their final trimester. Additionally, imported HEV, originating mainly from the Indian subcontinent, is also seen in Israel. Awareness of this disease is important both among physicians in Israel as well as those in other industrialized countries.
