How can prion diseases be prevented?

Not much. There's not much we can do at present as some forms of prion diseases have to do with genetic mutations. Prion diseases can be transmitted by exposure to prion-contaminated tissues during a medical procedure. Another type of prion disease in humans, vcjd, is acquired by eating beef products obtained from cattle with prion disease. So stay away from beef from places with endemic prion disease.
There are many forms. of Prion disease from Fatal Familial Insomnia to Kuru. Generally speaking I would avoid eating brains form any source (see my editorial in the British Medical Journal Lancet ) also avoid blood products from potentially contaminated sources where there have been cases of Variant CJD (Mad cow disease). Some cases occur through spontaneous mutations, corneal transplants and contaminated allographs.
Little. Prions are infectious only in great concentration. Concentration occurs when there is a cycle of of infection-->ingestion-->infection-->...As with kuru when peopl eat the brains of infected ancestors, become infected and are then ingested. The same can happen with mad cow disease when infected cattle are themselves fed to cattle. So, avoid beef fed on cattle parts.

Curious about prion disease, after reading an article. How rare is it? What are prevention methods? How many cases per year.

See below. This is a group of diseases. All uncommon. The only preventive measure it not eat meat from animals that may be affected. For more information you may consult these two sites. https://www.niaid.nih.gov/diseases-conditions/prion-diseases http://www.cdc.gov/prions/index.html. Read more...

Why do prion diseases have such long incubation periods? Can they be stopped at all?

Supportive care only. The duration of incubation of prions is probably related to the folding state of the inoculum and the sequence of the host prion protein. At present, there is no effective treatment for prion diseases, and all are universally fatal. Read more...

Are prion diseases more common among people who hunt and eat what they kill? (Due to the meat not being tested for disease)

Dept of Health. Contact your local Department of Health and ask if prion disease is a problem in your region. It is unlikely it would be infecting your venison. Read more...

Have we gotten ahead of the game on prion diseases? Or are prion diseases likely to be major social/public health problems down the road?

Hard to say. The mad cow epidemic and subsequent outbreak of vcjd was brought to the surface by feeding animal proteins to herbavores. Science has quite a lot more to learn about prions. They are likely to be involved in other processes and not all related to disease states. Read more...

Prion disease. Fatal Familial Insomnia, CJD, Varient CJD, Scrapie, KURU all have in common the relentless progression caused by infection with something that is less sophisticated than a virus. Most are acquired from ingestion of contaminated brains (or meat in the case of Varient CJD) CJD can be contracted through corneal transplant or transfusion of contaminated blood or blood products. .

How common are prion diseases?

Not very. Hi, the most common prion disease is CJD, with a uniform incidence of approximately 1 case per million population both in the United States and internationally. Familial forms of prion diseases, such as GSS and fatal familial insomnia (FFI), are much more rare. About 10% of cases of CJD are familial, with an autosomal dominant pattern of inheritance linked to mutations in the PRNP gene. Read more...

What is the definition or description of: Prion diseases?

Can you get a prion diseases from gm food?

No. Gm food have not been shown to have any ill effects on health, . Read more...
No. There is no evidence--nor reason to think--that gm food should or could generate or increase infectious prions. Without comment on whether gm foods are a boon or a bane, the only way i could imagine this happening would be if some evil scientists deliberately created a gm food to generate bad prions in order to eliminate their own financial base ;).
