That may be a little optimistic, but I could see it happening if the virus does turn out to be seasonal.
From living and travelling in 44 countries I believe the flu is not especially seasonal, it surges in December partly/significantly due to cold weather and weakened immune systems and obviously mixing/returning in the holidays but my March that years strain has run out of people to infect, the herd immunity that is spoken of. I have got used to getting touches of flu and colds randomly through the year living near the equator. Good for my seasonally affected etc.
Seperation will significantly extend the time to this herd immunity with Coronavirus.
Bearing in mind a huge number of vulnerable people are (often successfully) immunised from the flu every year and leading to a far lower death rate and we don't have this for Corona with is more contageous, contagious for longer.. Well I guess watch ecuatorial and Southern hemisphere countries to see how it will keep going in the northern hemisphere past April and into the summer. We have been extremely fortunate on timing, had this hit in November.. Ouch and Argentina, Southern Brazil will be in hell during June/July.
Anyway just pondering aloud, hard to keep all the mental balls in the air on this one... I don't see it going, just slowing, resurging, hopefully changes in diet and lifestyle will help though many are just getting even fatter staying at home. The genetics boys say it seems to mutate slowly, maybe though we have a re-infectable strain by next December.
I expect after this and the next mass quarantine people will just settle into accepting a lot of deaths to save the world economies but these numbers will be lessened somewhat by intense efforts now.
Time to make tea.
