[Research on the rubella epidemic of 1973 in Turin. Virological data].

During the outbreak of rubella in Turin in 1973, 110 newborns, whose mother's pregnancy clash with the epidemic, were studied for the elimination of rubella virus. 708 samples were in total examined, through inoculation in primary cultures of African green monkey kidney (and study of the possible interference with ECHO-virus type 11), and partially in RK 13 and SIRC continuous cell lines. No strain of rubella virus was isolated, and the Authors conclude that the virus involved was particularly benign from a teratogenetic point of view.
