Great swine flu epidemic, first world war killed 21 million people in four years while the swine flu did the same in first four months.
It arose almost unknowingly, normal, non lethal but in 1918 it grew severely. We still don't know how and why.

In that time prisoners were tested for the flu injection experiment and promiced for pardon if survived.
But none of the prisoners carried flu, instead ward doctors grew ill and died. Explanation could be the flu might had passed through prison earlier and volunteers might have developed natural immunity.
