Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Serious question, because I’m not an immunologist: didn’t we eradicate polio? How do we keep finding it in weird places every once in a while? Is it actually just that good at surviving in adverse, ex vivo conditions?

There's plenty of infectious agents that can just lay dormant almost indefinitely.

There's major concern about viruses coming from the melting permafrost in regions like Siberia.

If you want to hear something even more terrifying, prions can last about indefinitely. Chronic wasting disease in deer is particularly bad because a deer might die and its remains will decompose into the earth. But vegetation will later grow, and some of those prions will have contaminated the new vegetation. A new deer will get infected by eating that vegetation, even years later.

Technically, it's never been proven that deer can contract CWD from the ingestion of plants. Although, apparently mice and hamsters can.

But, prions suck. Even bleach won't kill these bastards.

Hell, although there's no real, strong evidence to suggest it actually has made the jump, and research has shown it would be really difficult, its probably not impossible. If you ENTERTAIN the stories about the people suspected of possibly contracting CWD, it's even more scary. (Yes, I know the study does more to disprove human infection, than not, but it does a good job of outline suspected cases)
