Thanks for this. Another excerpt I found particularly interesting:
> Internal travel restrictions in England, Scotland and Wales in the United Kingdom were predicted to have minimal impact on the magnitude of the peak and in delaying the spread of the epidemic – possibly because there are some densely populated urban areas and relatively high levels of population movement. However, in a recent review, it was estimated that a combination of internal and international travel restrictions could help to stagger the impact of a pandemic within a country such as the United Kingdom, by desynchronizing localized outbreaks.
This is exactly the kind of unforeseen interaction effects I had in mind a few comments above when I said I'm not convinced we are able to conclude that "travel restrictions do not work" from the present studies. This particular effect will quite obviously also depend on epidemiological factors such as the length of incubation period, whether the disease is transmissible during the incubation period and so on.
There are far too many variables to account for and far too little experimentation has been done so far to conclude anything firmly.
