Prions

All prion diseases are inevitably fatal; there are no known cures. You can inactivate them, not kill them. They are technically not alive. Think of them more like a substance, a protein to be exact.

Yes a person who ate prion infected food using hands can cross-contaminate other things if he touches the food infected with prions with his hands.

Prions primarily affect the nervous system by causing misfolding of proteins, leading to neurodegenerative diseases like Creutzfeldt-Jakob disease and mad cow disease. However, recent research shows that prions can also affect other cells and tissues in the body, impacting the immune system and possibly playing a role in conditions like Alzheimer's disease and Parkinson's disease.

A prion is a misfolded form of a protein molecule, specifically the prion protein (PrP). It can induce other normally folded PrP proteins to adopt the misfolded conformation, leading to the spread of prion diseases.

A prion is a small infectious particle that contains a protein. These contain no DNA or RNA. These cause Creutzfeldt-Jakob disease, Scrapie in sheep and Kuru. These are deadly and progressive nerve wasting diseases.

Mutated prions have an altered conformation of their normal prion protein shape, leading to misfolding. In the misfolded state, prions form aggregates and can have various shapes, depending on the specific mutation. While some may resemble rod-like structures, prions can also form sheets, fibrils, and other irregular shapes.
