0.1 new cases per 100,000 population of Hepatitis E was notified in Australia 2002 (Yohannes K, Roche P, Blumer C et al. 2004, Australia’s Health 2004, AIHW) ... see also overview of Hepatitis E.

This disease is uncommon in the United States. (Source: excerpt from Viral Hepatitis A to E and Beyond: NIDDK)
Major waterborne epidemics have occurred in India (1955 and 1975-1976), USSR (1955-1956), Nepal (1973), Burma (1976-1977), Algeria (1980-1981), Ivory Coast (1983-1984), and most recently in Borneo (1987). To date, no outbreak has occurred in the U.S., but imported cases were identified in Los Angeles in 1987. There is no evidence for immunity against this agent in the American population. Thus, unless other factors (such as poor sanitation or prevalence of other enteric pathogens) are important, the potential for spread to the U.S. is great. Good sanitation and personal hygiene are the best preventive measures.
MMWR 36(36):1987: Two outbreaks of enterically transmitted non-A, non-B (ET-NANB) hepatitis occurred during the late summer and fall of 1986 in rural villages in the State of Morelos, Mexico. This is the first reported instance of epidemic transmission of this disease in the Americas.
MMWR 36(16):1987: Outbreaks of enterically transmitted non-A, non-B hepatitis occurred in 1985 and 1986 at refugee camps for Ethiopians in Somalia and the Sudan. (Source: FDA Bad Bug Book)
The following statistics relate to the incidence of Hepatitis E:
The term 'prevalence' of Hepatitis E usually refers to the estimated population of people who are managing Hepatitis E at any given time. The term 'incidence' of Hepatitis E refers to the annual diagnosis rate, or the number of new cases of Hepatitis E diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
