Unless a vaccine is found, just as we have a Flu season every year, there may be a COVID-19 season each year. We are we supposed to do? Shut down the country every year during COVID season?
Not a feasible option. Protect the most vulnerable as best you can and, at some point, you have to let this thing run through the rest of the population.
THE most effective things...WEAR A MASK, and WASH YOUR HANDS.
By "flu season", we will have an adequate supply of commercial masks and plenty of hand sanitizer. The Italian subsidiary of the firm my wife works for got through their crisis with NO DEATHS just by stringent application of those two things.
The whole "masks don't work" meme is bullshit and probably originated in a Chinese disinformation tactic.
Given how Coronaviruses are, we are stuck with them for good. However, it’s likely that we will see plenty of more mild strains at the same time.
