New account, publication is made by someone @vaccines.net which claims the following "We are concerned that the current outbreak of COVID-19 is actually a bioweapon attack and may be linked to the US anthrax attack of 2001, which originated from the US army base Fort Detrick."

The publication has not been peer reviewed, and quotes several times articles published by the original author with similar claims.

Are we spread miss information in HN now too?

Prion diseases terrify me. Especially having been in the UK eating beef at the time of the BSE outbreaks in the 1990s. I wonder if there have been studies on the scale of potential latent vCJD/Prion disease in the population?

Whenever a topic about something that could potentially destroy humanity comes up (say, climate issues), there is always some comment that makes a reasonable argument of why things are not as bad as they seem. This never happens when prions are the topic.

Actually there is a positive anecdote often cited. The Fore people of New Guinea engaged in ritual cannibalism which lead to the propagation of prions across generations. When they stopped, the generations of disease also stopped.

I do wonder if it’s possible that vaccines that are designed to make the body produce certain parts of the spike protein could lead to prion diseases accidentally. Are we sure of the proteins coded for and also that this coding can’t produce misfolded proteins? It’s pretty unlikely but also we don’t have long term testing of these proteins in the body. * please note I’ve had the first dose of Astra Zeneca and intend…

I'm unsure of how vaccines are related here. First case was in 2015, and cases are relatively contained to an area

Did prions survive cooking? I'd have thought cooking the beef would have killed them.

Prions are incredible hard to destroy. To quote from Wikipedia: `Prion aggregates are stable, and this structural stability means that prions are resistant to denaturation by chemical and physical agents: they cannot be destroyed by ordinary disinfection or cooking.`

That's not good.

As mentioned in previous submissions, because it is happening in a certain area, industrial pollution can be considered as a possible cause as well.

That was the going assumption as far as I understood (I'm from the area). They're hasn't been direct health advise on areas to avoid either, so it's slightly disconcerting.

Are prions contagious through contact or only eating?

Actually, there is some good news. Many types of prions diseases do not spread from animals to humans (so far). There have been some studies around this with CWD, but also Scapie has been around for hundreds or even thousands of years and never made the jump. Even in areas with CWD, we see that herd numbers do typically rebound. It's believed that there is some genetic factor that prevents the onset of the symptoms, like the body's proteins are less likely to fold in that way, so you only accumulate what you eat, or that the body can clean up the misfolded proteins. So it's not like it would wipe out everyone. I think I remember reading that some people are also researching prion treatments with some limited sucess. I would imagine they would come up with something even more quickly if there was a epidemic type of situation, similar to how medical researchers around the world focused on covid.

The Fora people even developed a prion that confers resistance to kuru:

> researchers [...] discovered a naturally occurring variant of a prion protein in a population from Papua New Guinea that confers strong resistance to kuru

> This community [...] has developed their own biologically unique response [...] this genetic evolution has happened in a matter of decades

If you took affected neural tissue and burned it to ash on a wood fire, there remains (although low) infective potential but probably only if you were trying in a lab. It takes 1000 C incineration to defeat infectivity and even then they’re still detectable. Composting so the proteins are broken down biologically is also an alternative. No amount of cooking prions that leave anything you want to eat makes infected ma…

Agree that cooking is not an option.

You can actually get that 1000C down to 600C if you also soak the tissue in acid prior to burning.
