Rise in number of CJD victims
![]() There has been a statistically significant rise in the number of people diagnosed with the human form of mad cow disease, government scientists report.
There are now 69 known victims of variant Creutzfeld Jakob disease (vCJD), the Spongiform Encephalopathy Advisory Committee said. It is the official body monitoring the progress of the disease. Its spokesman for SEAC said there are a further seven "probable" cases but added that vCJD can be identified with absolute certainty only after death. "The number of cases reported now indicates a statistically significant rising trend of around 20-30% per annum to date," the spokesman said. First consistent rise Peter Smith, acting chairman of SEAC, said the new figures meant that an additional 10 people contracted the incurable disease in the last 12 months, but the figure will have risen by between 12 and 14 by this time next year. Mr Smith added that the announcement, made on Monday evening, represented the first time a consistent rate of increase in the number of people contracting vCJD had been confirmed. The SEAC spokesman also announced that the cluster of cases of vCJD that were recently discovered in the Leicestershire village of Queniborough could "throw new light on the mode of transmission of vCJD".
Dr Robert Will, director of the government's CJD surveillance unit in Edinburgh, said meat processing methods in the 1980s may have led to contaminated beef ending up on children's plates. The theory could explain the relatively high incidence of the disease among young people - an issue which has long been debated by doctors. Although the incubation period of the disease is normally 10 years, the youngest two victims first showed symptoms at the age of 14 and many others were also teenagers. Conventional CJD rarely occurs in people under the age of 50 and most victims are in their 60s.
