In this particular case here in this topic: there's a voting (but seemingly not commenting) population that just really wants COVID-19 to be a flop. I'd be tempted to say that's a political position, but in fact politicians have largely unified on this (finally). Maybe it's a counterculture or conspiracy thing.
I mean in the last week, multiple legit stories have been flagged off the home page about Coronavirus. Go back and look at the comments on the story that hit the frontpage about Trump trying to buy exclusive rights to a vaccine... A story that was ultimately confirmed as true. But yet it was flagged off the frontpage by Trump supporters that denounced it as "fake news" of course, as if he doesn't regularly do things that would be unbelievable without video/audio evidence.
Meanwhile, any comment, like yours, that mention the BLEAK REALITY THAT THIS IS GOING TO LAST MORE THAN 3 WEEKS is getting downvoted. Systematically. As if downvoting you changes basic fucking maths.
Frankly, I think it's massive cases of denial. I think people are just starting to get an image of how bad this is going to be and how fucked our social structure is about to be. Especially if this drags on for many months (like those of us paying attention understand is likely).
HN has just generally been particularly insufferable the last week and a half, but at least the really obnoxious deniers have mostly ... stopped.

(sorry...hard to stop)
People also chronically overinterpret whatever they see on HN that they don't like—again, myriads of comments make the opposite generalization to yours. Randomness plus cognitive bias equals narrative.
As for voting patterns, I'm not sure I agree. For example, it's not true that downvotes used to be reserved for something factually incorrect. The voting mechanisms are subject to the same psychology as they always were.
Your comments often argue in edgy ways that are not exactly in keeping with the spirit of this site. From my perspective that's more likely why they're getting downvotes. I took a quick look and your comments that I saw which were upvoted don't seem to have this quality. Usually, when people complain about downvotes, there's something in their comments that they're not aware of, but which is apparent to readers. Of course there are also downvotes simply because of disagreement, but all comments get those, and they usually get fixed by corrective upvotes if there's nothing else in the comment that has a downvoteable quality.
