It can happen, researchers say
Prions, the infectious proteins that cause lethal neurological diseases such as bovine spongiform encephalopathy in cows and variant Creutzfeldt-Jakob disease in humans, can be transmitted in aerosol form, according to new research conducted by a team of scientists from the University of Zurich in Switzerland and the University of Tübingen in Germany (Haybaeck J, Heikenwalder M, Klevenz B, et al. Aerosols transmit prions to immunocompetent and immunodeficient mice. PLoS Pathog. 2011;7(1): e1001257.)
