I don't think it will be talked about in that way. Especially if this is a bioweapon created in China which accidentally escaped. No one wants the dirty laundry spilled of all the countries who are doing bioweapon research. China is too powerful economically and surely has too much dirt on everyone else to go down alone. So I believe the official position will be that it's either not engineered at all ("inconclusive"), or just an unfortunate accident related to legitimate non-weapon research. Worst case scenario is US, EU, etc. do a little finger wagging that China needs to "stop eating bats" and then it will be let go. Of course, that's just the official/public position.
China is a signatory to the Biological Weapons Convention [1]. The US State Department regularly issues a compliance report about it (and other international agreements). Here [2] is how it summarized China's compliance in August 2019:
"Information indicates that the People’s Republic of China (China) engaged during the reporting period in biological activities with potential dual-use applications, which raises concerns regarding its compliance with the BWC. In addition, the United States does not have sufficient information to determine whether China eliminated its assessed biological warfare (BW) program, as required under Article II of the Convention."
(That's followed by some more details, which you can read about in [2].)
Given this ongoing scrutiny, it would be very surprising if a smoking gun that the PRC has in fact been developing bioweapons were just swept under the rug.
I'm making the assumption that there's a MAD situation here with regards to revealing bioweapon programs. I am assuming every major economy has clandestine bioweapon programs and that every major economy has the dirt on everyone else's bioweapons programs, regardless of treaties. So if the US, or someone else, comes out hard against China for an alleged bioweapon program, then China will release information about US programs. That is why, in my opinion, the media headlines and public positions of the major players will be a polite fiction. The truth may wind up buried in some report somewhere, but it won't make the same kinds of headlines that "kooky bat eating" makes.
One of the issues in treaty monitoring for bioweapons is that so much research is inherently dual-use. The CDC synthesized Spanish flu and infected primates to study why it was so lethal.. they've even tweaked regular strains of flu to make them more lethal, in order to study what genetic factors influence virulence and mortality. There are legitimate, compelling reasons to make even genetically engineered pathogens. Even straight-up engineered bioweapons can be used to study defenses.
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.
But the point of a bio weapon is not to kill everyone,just your enemy. So i guess you would want it to be very deadly and not spread to far. And i imagine you would want to primarily take out young healthy people (soldiers) not the eldery and sickly. (I assume)
This virus spreads quickly (check) but has a mortality rate of 2%, mostly the old and already immunocompromised. If that's a bioweapon it's a pretty ineffective one.
If you want to extinct homo sapiens you should probably make a virus that infects everybody and has as little symptoms as possible and then kills them a year later.
We don't know yet if this virus has any long-term consequences. HIV would seem harmless if we estimated its effects after 1 month.
But I don't think bioweapons need to be deadly. If you can make a virus that kills 2% of people but shuts down global trade with your main economic competitor for example - that's quite useful (if you don't care for morality of course).
I'm not persuaded it's human-created, but it's a possibility.
2% so far, it's very early in the lifecycle of this epidemic and most people go days without showing any symptoms.
The mortality rate will rapidly increase as it spreads to areas where it can overwhelm the local infrastructure. Not every country is capable of creating hospitals in 6 days like China, and China has a lot of experience responding to these crises since the Sars days.
We are only a month in, it's too early to really count mortality.
