[Possible long-term prognosis in epidemiologically significant virus infections]

The long-range prognosis of viral diseases must be assessed differently according to their geographical occurrence. The genetic disposition, environmental factors and additional infectious diseases play a decisive part here. Vaccinations are the most important measures in the prevention of these infections. The spectrum of possible chemotherapeutic intervention for viral infectious diseases is very small, which usually makes specific treatment impossible. The most important infective viruses epidemiologically, which lead to persistent complications, are discussed in detail as follows: influenza virus, measles virus, human T-cell leukaemia virus, human immuno-deficiency virus, hepatitis B and C virus. In a discussion conclusions are drawn from the virologist's point of view for a possible long-range prognosis, which depends on the one hand on the infective agent and on the other on individual reactivity. The last chapter talks about insurance medical aspects of the most important infective viruses, which have already been discussed virologically. Some scientific developments are shown which could be future solutions of problems in diagnosis and prognosis. Such new developments could help insurance medical officers to important decision parameters for long-range prognosis, which are still largely missing at present.
