I am pretty sure that in recent weeks I had come across a term that describes a kind of poetic justice that occurs when someone becomes a victim of the very thing that s/he has been denying to exist.
Boris Johnson has already become that, but I cannot remember the term.. or if we need to create a term.
New research obsession of mine to find the right descriptor (or meme or whatever will accurately describe such phenomena and several people are coming to realize that those invisible lil thingies, aka viruses, can be a "real" force to be reckoned with).
Even when someone is a denier, we can still feel some passion for the human side of severe illness and perhaps succumbing to death when they become the victim, even though their prior arrogance can be challenging of such sympathies, too, as shown in this article, including a video from Johnson, too.

The below article about Landon Spradlin deals with coronavirus deniers becoming victims, too.
