Abstract:
We have compared the prevalence of antibody to HAV in sera collected from healthy individuals of Milan in 1958, 1977 and 1992 respectively. The results show a dramatic reduction of HAV circulation likely due to the considerable improvement of socioeconomic and hygienic living conditions which have occurred in Italy during the last decades.
