There has been much criticism worldwide over national governments' failures to act quickly enough to contain the spread of Covid-19; one needs only look at the frightening death tolls in countries like Italy, Spain and the U.S. to appreciate the merit of such criticism. But in my view, much of that failure is a result of our refusal to recognize the interconnectedness of today's world.
When the bug first broke out in Wuhan, China, our initial response was to check all passengers travelling from the afflicted area. Not a bad first start perhaps, but it was predicated on the assumption that such people could be effectively isolated, an assumption that quickly proved illusory.
