The “German measles” epidemic in Indiana☆

Abstract The rubella epidemic of 1964 in Indiana failed to significantly increase the reported incidence of congenital deformities or the perinatal mortality rate, because the authors estimate that only 0.38 per cent of the women who were delivered in 1964 had rubella, and only 15 per cent of these were delivered of deformed infants. Some of the congenital deformities produced may have gone undiagnosed and, therefore, unreported.
