Umm... at the risk of being whooshed, did the OP not really catch that this was from r/nosleep? That's a subreddit for people to write scary fiction. This is no more an article than something posted in The Onion.
That aside, the story is well-written, but there are a few missteps and it really reads like an American fantasy of what life in Communist China is like.
Just from a quick read, I noticed:
1. The myth that all of the nukes were dismantled in the 1970s. Tons of Americans with friends and family in the military in the intervening years could easily debunk this, myself included. But if your story's central conceit is that everything's a big old conspiracy and coverup, there's a convenient "that's what they want you to think" response.
2. The assertion that the "coronavirus" was really caused by a bioweapon that was being secretly sold in the meat market. It supposedly escaped when the glass vial was dropped and shattered. That only happens in movies. In real life, something like that would be in plastic, and in a well-insulated case that could be run over by a truck without getting damaged. Hell, those kind of agents are kept under such strict control that there's no way one could leave the building.
3. The Chinese people are not as easily cowed, controlled, or duped as Westerners like to think. There's a loooooong tradition of massive government protests that no government, including the Communists, has ever been able to stop, and the masses aren't going to just look the other way when millions of their friends and family members who "fled Wuhan" never showed up anywhere.
4. The misconception of why people wear masks - in China and Japan, from what I've heard from people who live there, you primarily wear a mask when you are sick and want to avoid infecting others. Which works far better than wearing a mask like some people do in the US, to try to avoid being infected.
So yeah, enjoyable read, but it's not "The Stand" by a long shot.
I hope the OP was a whoosh, because otherwise... dude.
