Some recent articles and health experts (an article in the Daily Mail may have reported on this) have states that it is pointless to restrict travel.

Is that an accurate statement?

For example, suppose in the first or second week of January 2020 air travel, cruise lines, and cross border travel generally, was prohibited? In principle, that might have curtailed and contained the spread of COVID-19?

Perhaps curtailing cross-border travel in March 2020 is ineffective for the 109 countries so far experiencing infection because community transmission has now become a more dominant means of spreading the infection that importing the virus into the country.

Having missed the opportunity to panic early, back in December 2019 or January 2020, and contain the virus, it is no longer as effective to restrict travel in March 2020, if indeed it is effective at all. Or is it helpful?

Perhaps at this stage, social distancing is more important to slow down the virus spreading.

What are your views on restricing travel to slow COVID-19 spreading?
