You know what the real solution is, don't you? We should all don Hazmat suits for the rest of our lives.These should be fitted with a range of tubes and catheters, so we never have to unzip, even to carry out basic bodily functions. This will make forming relationships with other human beings virtually impossible and sex, and thus procreation, will be unachievable, but at least the currently existing humans will be safe from not only Covid-19, but all other contagious illnesses.
Of course, the downside to this plan is that the human race will die out within a few generations, but at least the existence of all of us will be stretched out to the absolute maximum duration. Centennials, here we come! Liquidised birthday cake through sterilised straws! 
In fact, I think we can top even this! We should all make a universal pact to kill ourselves in the new year - humanely; we'll use the best technologies available. After all, dead people can't catch viruses, or be exposed to any risk whatsoever. It's the ultimate in safety. :) :)
