Many deniers have come down with Covid-19 after refusing to take precautions.
And as AmpMadScientist has said, there will be more.
Covid doesn't care about your belief system. As with cases in general, many deniers had only minor symptoms, while others felt truly awful and some few needed hospitalization. Only a small percentage of deniers have died, making it easy for those with an agenda to continue pushing the false narrative that it's really nothing to worry about - despite the loss so far of more than three million souls.
It is always a human tragedy when someone is struck down by this pandemic. Ironic when it happens to deniers, whose deaths sometimes are literally due to vain demonstrations of their disbelief. It isn't just conspiracy theories that they're spreading.

Hans Gaarder in Norway, a very vocal conspiracy pusher who threw several illegal house parties
despite already being sick with covid and died of it just a few days later. At least a dozen who attended the parties contracted the virus; some went on to infect others.
In a post to his Facebook page before the parties, Gaarder said: "What could be the reason for the measures 'to prevent infection' for something that will be like a cold or mild flu? Could it be to camouflage that coronavirus is not transmitted from person to person?"
It's human nature to want to believe a story which reinforces one's existing point of view, and to resist any thought that might challenge it.
We're also hard-wired to feel strong, even virtuous, when we know others think the same way.
Those who deliberately craft disinformation are quite aware of this; I prefer to think the millions who share misinformation without checking it probably don't realize they are participating in mass deception.
There's no vaccine against blind acceptance.
And herd immunity is no protection against the herd instinct.
