[New findings in the epidemiology of viral hepatitis]

At present there is not yet a causal therapy of hepatitis. The modern state of knowledge on the mode of transfer, on the persistence of the causative organisms and the immunological reactions evoked by the causative organisms gives the possibility for new ways in prevention. The HBs Ag-carriers are a reservoir of causative organisms in the sense of chronic carriers. In a particular degree they endanger the personnel of public health. A supplementation of the general hygienic preventive measures by the immunoprophylaxis is desirable.
