Interesting report from 2007 on the results of various ways to deal with a pandemic in 1918. Worst-case handling: slow to respond, lifted the restrictions too early - cities that did exhibited a double peak, once before the lockdown and a second time after it was lifted, followed by a second lockdown - and so on. One telling quote:
The ninth tenet, experiment, could not be demonstrated directly because of the paucity of influenza pandemics in the past century
Looks like they can update that part soon because of the large-scale experiment the US is now running, although unfortunately only at the poor-response end of the scale.
Our study suggests that nonpharmaceutical interventions can play a critical role in mitigating the consequences of future severe influenza pandemics and should be considered for inclusion in contemporary planning efforts [...] The history of US epidemics also cautions that the public’s acceptance of these health measures is enhanced when guided by ethical and humane principles.
