Is it possible we’ve permanently eliminated some strains of colds and flu with the year long quarantine?

Yes, maybe. There are a couple of strains that there have been zero reported cases of and scientists think they may have gone extinct.  Which is good news for flu shot makers because they just hope they are right about which strains they develop vaccines for months in advance of flu season.  Fewer types of flu strains means they will have higher likelihood of picking the correct strains to vaccinate against.
