It seems to be, even COVID-Reluctant FoxNews had a report on it:
As someone who's wife had long COVID from May 2022 until about 2 months ago, that's unfortunately the story. Long COVID people have a variety of symptoms from brain fog, dizziness, taste/smell loss etc. and there's little info from doctors about it.
I have no idea if Fred's vocal cords are from COVID or anything else, but with the risk of turning this into a Long COVID discussion, it does fuck with things in a weird way for a short to long time.
Between COVID, RSV, etc. there's so much shit going on right now, so many of it impacts your nose, ear and throat, it could be anything. It must really suck for Fred as your job is talking 4 hours a day and he sounds like shit and it even sounds like it hurts to talk.
