title: [vCJD epidemiology in France].
abstract: Variant Creutzfeldt-Jakob disease (vCJD) is the only form of prion diseases linked to bovine spongiform encephalopathy (BSE). The disease was first described in the United-Kingdom (UK) and France is the second affected country with 21 cases. Clinical, genetic and neuropathological features are the same in both countries. Comparison of the total number of cases in France and in the UK, according to dates of onset, shows that, in France, the maximum incidence seems to be five years delayed and that, in the UK, the number of vCJD cases regularly decreases since 1999. Delayed exposure to contaminated beef products in France compared to the UK could explain this temporal gap. Three cases of vCJD after transfusion of labile blood products were observed in the UK. No such of cases were observed in France but three patients developing signs of vCJD in 2004 were blood donors. A total of 42 recipients were identified with 17 recipients still alive.
