That's a whopper and a half. Any supporting evidence for those claims at all?
I have no evidence, as I’ve read so much information over the last few months and I can’t remember where I saw this but, I believe what he’s said is true, in fact it was an interview with some scientist chap.
Obviously with new evidence they may have changed their minds now, but early on they believed high viral loading was the cause of the more severe symptoms, which I guess could be why we’re seeing less fatalities now, rather than the virus weakening it could simply be less people coughing in your face leading to milder symptoms.
As I say I can’t back it up, but he’s definitely not telling you a story.
