Uncle Doom is right again long time back!!! Thanks R. Wordsworth too for bringing up this prion thing for me to research further.

Though the microbiologists ended-up focusing on four viruses and detected potential signatures in all of them, prion-like domains in the spike protein were only predicted for one species: SARS-CoV-2. "No other even closely-related betacoronaviruses have such prion-like structures in their spike proteins," Tetz tells Forbes.

SARS-CoV-2 contains prion-like domains in its receptor-binding spike proteins. These prion-like domains may contribute to a nearly 20-fold increase in affinity for the protein receptor found in human cells, ACE2. This unique structural element may contribute to the human-to-human communicability of COVID-19.

Prions Are Forever. The lethal proteins are in the Hard-to-Kill Hall of Fame--and may be more common than we realize.

Can Prions be destroyed?
Prions are very hearty proteins. They can be frozen for extended periods of time and still remain infectious. To destroy a prion it must be denatured to the point that it can no longer cause normal proteins to misfold. Sustained heat for several hours at extremely high temperatures (900°F and above, i.e 482.222 degree celcius) will reliably destroy a prion.
