The virus will never go away unless somebody comes up with a very effective medicine. Masks won't prevent the virus from spreading neither.

It is impossible to quarantine the major cities forever and It is not wise to stop the economy neither because people die from hunger.

Long story short, there isn't a solution to this problem, yet.

Since we try to do them both, quarantine and work at the same time, we will suffer from both. Die from the virus and the hunger at the same time.
