I assume that the Russians did not caused anything nasty in Chernobyl that we aren't aware still, or that the war didn't bring some nasty substances to Europe via clouds and rain but... trust but verify.
But the US cases are an outlier.

In addition we have widespread atmospheric monitoring as well. You can circumvent that by releasing only substances that are not watched, but I don't think that's that easy, and you'd have to do it intentionally. Eg anything connected with fire will show up.
Some viruses that cause acute hepatitis are transmitted by water. And could be in a different genus than Hepatitis virus like Epsein-Bar; Is not impossible also that we would face a different new virus moving with the dust from one of the African endemic areas.
In any case liver troubles mean normally poison troubles, using a broad definition of poison, or immunitary problems
If it was covid I assume that the problem would be detected before and would appear widespread by in all continents at the same time. Hitting much harder the countries with more number of Covid cases.
But what we have instead is a (mostly) Atlantic European issue. (Spain, Denmark, Ireland, Scotland. Looks like a pattern here [1]). Europe had only two rare global events in this time interval that I am aware, the dust affecting the Western countries of Europe (if I'm not wrong), and the war.
