The odds are fairly slim. Wuhan is a large Chinese city that has a greater population than most countries.

There is going to be an (X) in Wuhan for any value of (X) anyone cares to name. The fog of uncertainty is still thick; nobody has much of an idea what is going on. Anyone claiming that they have a theory on where the virus came from is fantasising. The knee-jerk people probably don't want them drowning out a weak signal with useless noise.

There is only one Biosafety level 4 laboratory in China, and it opened... last year in... Wuhan. I am not saying there is a link, but I would not dismiss it too fast.

What is the probability that in Wuhan exists the only X in the vast country and Y happens only once in a decade or so

There'd be a bunch of BSL-3 facilities all over the place. It isn't like the Black Death or the Spanish Flu needed a BSL-4 facility to incubate in.

It is possible; but a lot of things are possible. It is a mighty leap from a starting point of basically no primary evidence and all the people who have on-the-ground access to evidence are very busy managing a rapidly growing crisis.
