How is vCJD transmitted?

Most reported vCJD cases appear to have been infected through the consumption of bovine meat products contaminated with the agent of BSE. In three cases, reported by the UK, the mode of transmission is thought to be through receipt of blood from an asymptomatic, infected donor.

Are kuru and Creutzfeldt-Jakob disease the same?

Kuru causes brain and nervous system changes similar to Creutzfeldt-Jakob disease. Similar diseases appear in cows as bovine spongiform encephalopathy (BSE), also called mad cow disease. The main risk factor for kuru is eating human brain tissue, which can contain the infectious particles.

What is Creutzfeldt Jakob Syndrome?

Creutzfeldt-Jakob disease (CJD) is a rapidly progressive, invariably fatal neurodegenerative disorder believed to be caused by an abnormal isoform of a cellular glycoprotein known as the prion protein.

Do vegans get Alzheimers?
