onus probandi incumbit ei qui dicit, non ei qui negat
Indeed....you deny that escapes occur.
I assert they do and have stated that quarantines slow the spread but do not prevent it.
A one sided debate is no debate at all.
My argument that quarantines only slow progress. Spanish Influenza St Louis (1918). Imposed earlier than other cities and REDUCED the death rate to 70% below the national average. It did not PREVENT the spread.
Escape vectors are impossible to contain 100% unless with limited controlled subjects. Once it is in the wild it can no longer be contained - only slowed. Which is what I stated in my original post.
