The RENARUB network, established in 1976, is the primary source of information on the epidemiological situation regarding rubella infections acquired during pregnancy and cases of congenital rubella in France. It consists of clinical laboratories identified by the French Health Products Safety Agency (ANSM) as part of its quality control program for testing for anti-rubella IgM antibodies. The objective of this surveillance is to identify, at the national level, rubella infections occurring during pregnancy as well as congenital rubella-related birth defects, and more broadly to assess the impact of the vaccination policy implemented in France with a view to eliminating congenital rubella. It demonstrated the limited impact of vaccinating only pre-adolescents and women of childbearing age—a program implemented from 1976 to 1984—on the incidence of rubella infections during pregnancy. The introduction of vaccination into the infant immunization schedule led to a very marked decrease in incidence from 1985 to 1988, with an incidence rate during pregnancy below 4.5 per 100,000 births from 1989 to 1992. However, in 1993 and 1994, and again in 1997, the network observed a resurgence in incidence, with rates of approximately 10 per 100,000 live births. This article presents the results for 1998. (R.A.)
