Every virus that mutates always mutates into something less potent than the original strain of that virus, a virus does not mutate into something more potent than the original strain.
This is a flat out lie.
Every years new flu strain is a mutation, some are more deadly, some are less.
BTW last year January 2019 I got the flu for only the second time in my life and it was a 3 week nightmare and it literally nearly killed me, I even had The Last Rites BUT note I comment it NEARLY killed me BUT it DIDN'T. Why? Because I am in very good health and I'm young that's why. Same thing with COVID-19 essentially, the death ratio is minute compared to the Recovery rate and also to the rate of those who have had the thing and displayed no symptoms.
What this means is this IF you are in already good health and IF you get COVID-19 you have a next to zero chance of dying from this thing, you probably will feel TERRIBLE for 2-3 weeks but you then will recover.
IF your immune system is already compromised via whatever preexisting health condition you have then yes you MIGHT take longer to recover OR you might die.
The majority of the world population in the worlds respective nations are not already sick with their immune systems compromised and/or fucked. The healthy population of each nation then should not be punished by being told to give up their human right to freedom and enjoying life so they are effectively under House Arrest so they can protect a small proportion who are old or sick with compromised and/or fucked immune systems. That would be INSANE to suggest that that should be done.
