Introduction of a new hepatitis agent in retrospect: genetic studies of Swedish hepatitis D virus strains.

The supposedly first outbreak of hepatitis D virus (HDV) infection in Sweden occurred among intravenous drug addicts in the Malmö area in the mid-1970s. Stored sera from this outbreak were used for viral RNA extraction and analysis. By sequence comparisons, the HDV genomes from those Swedish patients fell into two separate clusters, within which the RNA… CONTINUE READING
