London - Scientists are to re-examine controls against variant CJD, the deadly human form of BSE, in the wake of evidence that the disease might be highly infectious even when unwitting carriers do not display outward signs of suffering from the condition.
New research has raised fears that animals thought to be healthy and incapable of acquiring BSE could in theory pass the disease on. The results have also renewed concerns that humans not displaying CJD symptoms but incubating the condition may infect others undergoing medical or dental procedures.
