The end

The pandemic ended when the virus had circulated the globe, infecting enough of the world population, which is called herd immunity.

St. Louis

St. Louis handled the 1918 pandemic exceptionally well. Social distancing measures were put in place and followed. This kept a low death rate throughout.

How the measures were enforced

The measures were enforced differently across the states. In San Francisco, a health officer shot three people when they refused to wear a face mask. Arizona police handed out fines to those who refused to wear a face mask. Otherwise strict measures were just set in place.
