Just a reminder that greater infectiousness is worse than greater lethality.
Say you have two variants, variant S-spreader and variant L-lethal.
S kills 1 in 100 people and has a doubling time of 3.5 days
L kills 2 in 100 people and has a doubling time of a week.
First week L kills twice as many people of S.
Week 2 they kill the same number of people.
Week 3 S kills twice as many people as L
Week 4 S kills 4x as many people as L.
This is plain wrong. You have 2 variables there and can't claim that one has greater effect based on 2 examples. It can be refuted by a suitably chosen 3rd example, e.g. N-nonlethal kills 1 in 10000000000000 people and has a doubling time of 1 day.
Say you have two variants, variant S-spreader and variant L-lethal. S kills 1 in 100 people and has a doubling time of 3.5 days L kills 2 in 100 people and has a doubling time of a week.
First week L kills twice as many people of S. Week 2 they kill the same number of people. Week 3 S kills twice as many people as L Week 4 S kills 4x as many people as L.
