Prevalence of IgG Anti-HEV in Buenos Aires, a Nonendemic Area for Hepatitis E.

Hepatitis E virus (HEV) is the main etiological agent for the enterically transmitted form of non-A, non-B hepatitis (ET-NANB), and is associated with epidemic and sporadic forms of the disease,1 mainly in some developing countries.2 In Argentina, no ET-NANB hepatitis epidemics have been described, and no epidemiological HEV data are known up to this time. The aim of the present study is to evaluate the prevalence of anti-HEV in different groups of the population of Buenos Aires, an area considered to be nonendemic.
