What are the geopolitical ramifications if this is indeed a bioweapon?

Maybe this is naive, but I would assume if it was a bio-weapon it would be a lot more deadly.

Viruses which kill too quickly don't spread widely enough to kill a lot of people.

Good viruses kill after a few days of showing few (if any) symptoms so that they can maximise their spread.

This is the difference between epidemic and pandemic viral contagions.

Funny, I would have assumed the opposite. Nobody wins a war by releasing a doomsday virus that indiscriminately kills 5% of the world. But they can win battles by temporarily incapacitating an army, with no fear of loss of their own life if the winds blow in the opposite direction.

I wonder if this could happen because someone with a retrovirus got both infections at once?

It's not even necessarily someone with HIV - HIV is just one virus that is especially well-studied. If horizontal gene transfer in viruses is more common than we expect it to be, this genetic material could've been picked up from just about anywhere and we wouldn't necessarily know about that source.

Well, the conclusion of this paper is that the odds of this virus coming to be naturally are very small. Which is a very scientific way of saying "we think this was man-made". But, that is what the paper is saying. Extraordinary claims, extraordinary evidence is what I think. I feel the evidence here is quite small, but I'm not a bio-data-scientist.

Is it an extraordinary claim? The sequence matching should be easy to verify as the genome has been published. If the sequences are short or common enough maybe it would be a more likely coincidence. That said: What are the priors on a "natural" virus erupting in the only city in China with a level 4 biohazard facility? Source: http://english.www.gov.cn/state_council/ministries/2018/01/0...

Indeed, the paper seems to suggest that the natural occurrence of this virus is the extraordinary claim.

This has been pointed out in previous threads, but this Twitter is full of alarmist unscientific BS and it appears to be spammed with some regularity on HN recently.

The Twitter user seems legit. The Internet in general is full of BS yet we don't guilt-by-association the entire Internet.

We should question the veracity of the information presented. The nature of this fluid topic is a good example. I read the first part, a few days ago, and most of the information presented tallied with what was presented elsewhere. However, since then Dr. Eric Ding's profile has risen in prominence and the Twitter feed is commingling speculation with credentials, so it is entirely justified to question the validity of your source.

It would seem that there were doubts around the content in the Wikipedia entry.

As predicted in Contagion (2011). https://en.wikipedia.org/wiki/Contagion_(2011_film)#Scientif...

Seriously, this particular mutation of unknown bat virus + HIV is predicted in film. I recommend to watch it: it's very scientific, and has almost no action.

So if it's not extraordinary it's still going to require evidence, which without peer review we still pretty much have none.

This is evidence, but it requires corroboration from other evidence. Peer review doesn't provide additional evidence - it's just a sober second opinion that lends credence (or not) to the proposed evidence and interpretation.

Just wanted to clarify the language here.

That's very, very disturbing. If this is an engineered virus, why as a race do we keep doing these things to ourselves? Do we _really_ think that weapons of mass destruction won't be turned on us? Is our hubris so high that we think no one else can replicate what we built?

>Is our hubris so high that we think no one else can replicate what we built?

How do we know someone else hasn't already built what we've built? They don't exactly post these things on Facebook...

....which is why we have to build it too.
