Seroprevalence of hepatitis A virus antibodies (anti-HAV) in adult inhabitants of Wielkopolska region, Poland--the role of simple demographic factors.

Abstract

The risk for contracting disease after exposure to HAV in young (<40 years old) inhabitants of the Wielkopolska region is high. Apart from older individuals, also women and people with a lower level of education are more frequently seropositive. A low level of immunity to HAV should be an indication for vaccination against HAV , especially in selected groups.
