When you look at the other four coronaviruses the cause of 25 per cent of our common colds they do have this really stark seasonality... But we don't know how long it took for them to settle into that pattern.
SARS-CoV-2, on the other hand, is still in its infancy... This is a virus that was never known to infect humans before 2019, so it's still a lot of evolutionary pressure.
