But stringent control measures a la Singapore are appearing to be effective, at least in delaying things considerably. And whilst there is significant global inequity in prevalence, travel restrictions may still play some limited role.

That's not the same as self-imposed cancellation of travel. For one thing, even in most countries with established COVID-19, it's still very patchy: limiting spread between communities allows governments to focus resources, at least for the time being.
