TSE transmission through blood transfusion


Calculations show that in the UK it would be expected that blood transfusion from a person infected with vCJD to someone that would have lived otherwise for a further 20 years would have caused 10% of the cases of vCJD.

When the mathematics are done with sporadic CJD it is seems that this would cause around 1% of the CJD cases and hence in the UK only 1 case as a result would be seen every 2 years and also it meant that epidemiological studies would not be able to indicate transfusion risk at all unless extremely large numbers were involved in them.

The transfusion studies in hamsters have taken over from these mathematical models and the data concerning risks that have been put together since then have given rise to government action around the globe as a result of vCJD appearing in the UK.
