[Immunosuppression and endogenic viral reinfection (author's transl)].

The consequence of nonspecific immunosuppressive therapy is a more frequent appearance of virus infections in the patients. They are largely caused by herpes and papova viruses. In addition to primary and recurrent exogenous infections, endogenous reinfections also have great importance. Clinically there is a broad palette from severe to inapparent types of infection. The use of live virus vaccines is contraindicated during immunosuppressive therapy.
