How Is Mad Cow Disease Transmitted To Humans? It’s spread by eating beef products from a cow that has been infected. Both animals and humans can get the disease. People get a version of BSE called variant Creutzfeldt-Jakob disease (vCJD).
Can mad cow disease be passed from human to human? There is no evidence that people can get mad cow disease or vCJD from eating muscle meat—which is used for ground beef, roasts, and steaks—or from consuming milk or milk products. People with vCJD cannot spread it to others through casual contact.
Is mad cow disease Sexually transmitted? It’s also possible for vCJD to spread between people through blood transfusions. Yet there have been no cases of reproductive transmission, and there’s no scientific evidence that sperm carry the disease. There is a chance that the nasty prions could spread through macrophages—large white blood cells found in semen.
How long can you live with mad cow disease? The disease can also cause brain damage and lead to psychotic behavior, dementia, and coma. Worst of all, there’s no cure for vCJD and people usually die within 13 months of showing symptoms. Furthermore, it can take up to 15 years for symptoms to manifest themselves.

Is mad cow disease still around?
Scientists say more cases of Creutzfeldt-Jakob disease (vCJD) are still to emerge more than three decades after the “mad cow disease” scandal. Richard Knight, a senior neurologist based in Edinburgh, said there were still people “silently infected”.

Can you get CJD from eating beef?
A small number of people have also developed the disease from eating contaminated beef. Cases of CJD related to medical procedures are referred to as iatrogenic CJD . Variant CJD is linked primarily to eating beef infected with mad cow disease (bovine spongiform encephalopathy, or BSE).
Who is at risk of CJD?
Most cases of sporadic CJD occur in adults aged between 45 and 75. On average, symptoms develop between the ages of 60 and 65. Despite being the most common type of CJD, sporadic CJD is still very rare, affecting only 1 or 2 people in every million each year in the UK.
How contagious is CJD?
CJD patients usually die within one year following the onset of symptoms. An autopsy is very important in the diagnosis of CJD because it is the best way to confirm presence of the disease. CJD is not transmissible from person-to-person by normal contact or through environmental contamination.
