I think one thing we have now generally seen is that travel bans are ineffective measures at the start of an epidemic, because by the time you implement them it's already too late. Very useful for long-term control, but not short-term management
On the contrary, they have to be implemented quickly, or it's too late. Both Australia and NZ introduced travel bans very early.
