Time from onset of symptoms to death is generally weeks to months. [2] Spread to humans is believed to result in variant Creutzfeldt–Jakob disease (vCJD). [3] As of 2018, a total of 231 cases of vCJD had been reported globally. [5] BSE is thought to be due to an infection by a misfolded protein, known as a prion.
TSEs in non-human mammals include scrapie in sheep, bovine spongiform encephalopathy (BSE) in cattle – popularly known as "mad cow disease" – and chronic wasting disease (CWD) in deer and elk. The variant form of Creutzfeldt–Jakob disease in humans is caused by exposure to bovine spongiform encephalopathy prions. [4] [5] [6]
In most people with CJD, these symptoms are accompanied by involuntary movements. The duration of the disease varies greatly, but sporadic (non-inherited) CJD can be fatal within months or even weeks. [16] Most affected people die six months after initial symptoms appear, often of pneumonia due to impaired coughing reflexes. About 15% of people ...
While human cases have declined sharply since 2000, the disease can theoretically incubate for decades. Experts warned that a second wave could break out. Millions of Americans still can't give ...
The human form of BSE is broadly similar to Creutzfeldt-Jakob disease, but differs in a number of clinical and anatomical respects. For example, it affects younger patients (average age 29, versus 65 for the classic disease) and has a relatively longer course (median 14 months, versus 4.5 months). [ 7 ]
Variant Creutzfeldt–Jakob disease (vCJD), formerly known as New variant Creutzfeldt–Jakob disease (nvCJD) and referred to colloquially as "mad cow disease" or "human mad cow disease" to distinguish it from its BSE counterpart, is a fatal type of brain disease within the transmissible spongiform encephalopathy family.

The United Kingdom was afflicted with an outbreak of bovine spongiform encephalopathy (BSE, also known as "mad cow disease"), and its human equivalent variant Creutzfeldt–Jakob disease (vCJD), in the 1980s and 1990s. Over four million head of cattle were slaughtered in an effort to contain the outbreak, and 178 people died after contracting ...
