While he or I can’t speak for everyone of course, personal experience and what’s being reported by many others seem to back this up.
When I caught it in January, it wasn’t enough to put me in hospital but it was enough to keep me in bed for a couple of days and being too fatigued to do anything apart from go to the toilet. Oh, I also had the trots for a bit too. This time round it’s literally no more than a runny nose, a bit of sneezing, and feeling a bit phlegmy first thing in the morning. No fever, no fatigue, not even a headache to speak of. Those are all things I had first time round. From what Rammy has said, he’s been broadly similar compared to when he caught Delta in the summer. Of course, it might not just be solely Omicron that’s responsible for these milder symptoms that I, Rammy, and many others are presenting with. Previous infection and me being triple jabbed (although my booster was only last Wednesday so it wouldn’t have fully kicked in) may well be playing a part too. And no doubt that even if it gets proven beyond all doubt that it’s a lot milder, some will still sadly succumb to it.
