Mate it is wierd that they mention covid. He is lying in a hospital bed with blindness and paralysis. Covid contributes nothing to the story and depending on the different versions , he may not even have it currently.
It's adds nothing to the story, doesn't change it in any way or contribute to how he got to being bitten.
So why bother mentioning it? Other than to get more clicks during a pandemic.
Why does it ultimately matter though? It's just a news story.
