In June 2013 the government was warned that deaths, then at 176, could rise five-fold through blood transfusions. Whilst these restrictions may go some way to preventing a self-sustaining epidemic of secondary infections, the number of infected blood donations is unknown and could be considerable. Since 1999 there has been a ban in the UK for using UK blood to manufacture fractional products such as albumin. The UK government banned anyone who had received a blood transfusion since January 1980 from donating blood. Significant restrictions exist to protect the blood supply. A blood test for vCJD infection is possible but is not yet available for screening blood donations. The finding alarmed healthcare officials because a large epidemic of the disease could result in the near future. In 2004, a report showed that vCJD can be transmitted by blood transfusions. Blood products Īs of 2018, evidence suggests that while there may be prions in the blood of individuals with vCJD this is not the case in individuals with sporadic CJD. Jonathan Quick, instructor of medicine at the Department of Global Health and Social Medicine at Harvard Medical School, stated that bovine spongiform encephalopathy or BSE is the first man-made epidemic, or "Frankenstein" disease, because a human decision to feed meat and bone meal to previously herbivorous cattle (as a source of protein) caused what was previously an animal pathogen to enter into the human food chain, and from there to begin causing humans to contract vCJD. A 2012 study by the Health Protection Agency showed that around 1 in 2,000 people in the UK show signs of abnormal prion accumulation. In the UK, the primary cause of vCJD has been eating beef tainted with bovine spongiform encephalopathy. Average life expectancy following the onset of symptoms is 13 months. The length of time between exposure and the development of symptoms is unclear, but is believed to be years. In the later stages of the illness, patients may exhibit poor coordination, dementia and involuntary movements. Initial symptoms include psychiatric problems, behavioral changes, and painful sensations.
It was first identified in 1996 by the National CJD Surveillance Unit in Edinburgh, Scotland. The typical age of onset is less than 30 years old. The disease has become less common since 2000. As of 2020, precisely 178 cases of vCJD have been recorded in the United Kingdom, due to a 1990s outbreak, and 50 cases in the rest of the world. Treatment for vCJD involves supportive care. It is different from classic Creutzfeldt–Jakob disease, though both are due to prions. Diagnosis is by brain biopsy but can be suspected based on certain other criteria. Spread may potentially also occur via blood products or contaminated surgical equipment. Infection is also believed to require a specific genetic susceptibility. Spread is believed to be primarily due to eating bovine spongiform encephalopathy (BSE)-infected beef. It is caused by prions, which are misfolded proteins. The length of time between exposure and the development of symptoms is unclear, but is believed to be years to decades. Variant Creutzfeldt–Jakob disease ( vCJD), commonly referred to as " mad cow disease", is a fatal type of brain disease within the transmissible spongiform encephalopathy family.
