Abstract
In outbreaks of type A hepatitis in Los Angeles, California, USA, and Rosario, Argentina, virus particles were isolated from feces. The geographically diverse strains were identical in appearance and serological reactivity. They differed only in buoyant density, but inconsistent results in estimating this were obtained previously. The virus strains in the 2 epidemics were identical.
