Contaminated blood case: what is it about?. The affair began in 1987 with the publication of a series of articles in the magazines L'Express then L'Événement du Jeudi.
Journalist Anne-Marie Casteret, a trained doctor, reveals that stocks of blood contaminated by the AIDS virus were sold and used for blood transfusions, particularly for hemophiliacs. The authorities' inaction caused a scandal and led to two high-profile trials. On February 9, 1999, three former ministers were tried for their responsibility.
