Core Tip

Core tip: Discovery of hepatitis E came to lime light when 1978-Kashmir epidemic of hepatitis was investigated. Hepatitis E is being recognized as a clinical entity of reemerging importance. Hepatitis E virus has marked heterogeneity and infects many animals like bats, camel, chicken, deer, boar, mongoose, pigs, rats, rabbit and cutthroat trout. Originally reported as a major health problem in poor-resource countries, hepatitis E is now recognized as an important clinical problem in the developed world. Zoonotic foodborne transmission of hepatitis E virus infections has relevance in solid organ transplant population. Major advances have been made in managing chronic hepatitis E. Hepatitis E causes a number of extrahepatic diseases, including a wide spectrum of neurological syndromes. Hepatitis E vaccine -239, marketed in China, has shown high efficacy with sustained protection for over four years.
