You think this thing will become cyclical? Something to think about if you're older than 65, especially during the winter if this becomes a seasonal illness. We had to deal with smallpox for a long time before finally wiping it out. Makes you wonder if this is similar.
No. Not really cyclical. There are many variables that would disrupt calendar periodicity.
I just think the virus will escape mitigation. I also think the weather is a major factor, and all summers or winters are not the same. Variants are another obvious mechanism.
Mankind should have been wiped out by smallpox. It killed big %, but one of its subtle features was it sterilized male survivors. Pustules blocked sperm ducts. Easily corrected now, but not a few thousand years ago. We were lucky.
