No pumpkin----the VIRUS IS GOING TO spread regardless---you can't stop it. At best you can slow its spread down (giving it more time to mutate btw before herd immunity which is likely going to enable the virus to develop strains that spread easier (which we now have) and into strains that will become more deadly.......
The coronavirus is like a hole in the side of a ship. By slowing the rate the water comes in (the rate of infection) and keep it below the capacity of the bilge pumps (the capacity of the medical community) and you can stay afloat.
Herd immunity is like opening all the seacocks.
