In this article we review the epidemiology of rubella cases notified in NSW since 1991. Rubella (German Measles) is an infectious, generally mild viral disease. It is of public health importance because rubella infection acquired during early pregnancy often results in foetal anomalies (congenital rubella syndrome). Vaccination against rubella provides a high degree of protection, and rates of rubella and congenital rubella syndrome have been reduced by community vaccination programs.
