1Laboratoire de sérologie virale rickettsiales et chlamydiales-Institut Pasteur d'Algérie.
Almost all the rubeolic reinfections are not apparent and are without any risk for the fetus. The news born's case (2nd in children) which is described here, presents a bilateral cataract. We have found positive IgA, IgG and IgM and an antibodies avidity of 70%. Concerning the mother, there are no IgM. The IgM and IgA are positive. The avidity of the antibodies is upper than 90%. During her first pregancy, the mother was subjected to the search of the antibodies, the results are positive (title = 60 ul/ml) and during her second pregnancy, the mother had rubeollic contact with her eldest son. Our conclusion is that it is a congenital rubella resulting from a reinfection.
